Advantages of the Lovejoy S-Flex Coupling The simple design of the S-Flex coupling ensures ease of assembly and reliable performance. No special tools are needed for installation or removal. SFlex couplings can be used in a wide variety of applications. » Easy to Install » Maintenance Free » No Lubrication required » Dampens Vibration and Controls Shock » Torsionally Soft » Double Engagement Lovejoy Reformulates S-Flex Endurance™Couplings to Last 3X Longer Lovejoy is pleased to announce it has redesigned its S-Flex Shear Type coupling product tomake it the highest quality and longest lasting offering available in the marketplace. Lovejoy engineers reconfigured the material and have delivered a new and improved, longer lasting EPDM rubber sleeve. Lovejoy is introducing the redesigned product as “S-Flex Endurance™Couplings” to signify the increased longevity and other performance improvements. Shear type or sleeve type couplings originated in the 1950s and is a popular choice for pump and other uniform load applications where it gained early acceptance and has grown across many industries including wastewater, paper/pulp, marine, power, and steel. The shear type coupling is a very simple design and is comprised of two flanges and one sleeve. The torque is transmitted through the twisting of the elastomeric sleeve. The shear type coupling virtually eliminates the load on bearings and shafts and is excellent with vibration dampening. As with other elastomeric couplings, it is a lowmaintenance and non-lubricated coupling option. The reconfigured S-Flex Endurance™ coupling design has undergone extensive dynamic cycling testing by Lovejoy. The results of this testing prove the new and improved S-Flex Endurance™ EPDM material provides higher performance and enhanced durability than its previous iteration and is now the best performing brand available in themarketplace, lasting at least three times longer than before. S-Flex Endurance™ sleeve’s static and dynamic torsional stiffness tested at least 30% greater than the former Lovejoy material and out-performed the current competition. The Lovejoy product operated with more resilience and consequently less heat build-up than the previous material as well as the competitive products. Furthermore, post-test inspections showed the new sleeves are very durable under these extreme test conditions, as they maintained their tooth shape and displayedminimal wear. Improved EPDM’s S-Flex Endurance™Sleevematerial “key” features: Durability – Lovejoy estimates the new and improved material will be able to last at least three times longer than before. A longer service life is provided even at higher torque ratings. There is also a noticeable abrasion resistance improvement. Resilience – The rebound characteristics are significantly improved. The new Lovejoy sleeve material absorbs less frictional heat than the current competition. This heat build-up advantage leads to less wear andminimizes the possibility of coupling failure. Strength – The higher torsional stiffness corresponds with the elastomer’s overall increased toughness (tensile strength and tear strength). This allows many applications to use a smaller, less expensive coupling and still achieve the same torque rating. Heat Resistance – The sleeve’s temperature rises during operation due to the hysteretic behavior of rubber. The new sleeves exhibited fast heat dissipation and maintained a lower temperature than the competition at the same dynamic cyclic test conditions. The decrease in heat generation leads to a longer service life. Recovery – Resistance to permanent deformation as well as its elastic recovery has improved. The new and improved S-Flex Endurance™ coupling will continue to work well on electric motor driven applications with uniform loads such as centrifugal pumps, blowers and fans, screw compressors, some conveyors, line shafts, and vacuumpumps. Product UPCs have remained unchanged so components can be ordered with the same codes customers are accustomed to using. www.jbj.co.uk/s-flex-couplings.html #DriveLineHarmony

TM The reformulated S-Flex Endurance is the longest lasting and best performing EPDM product available on the market. The S-Flex Endurance™ coupling design is comprised of three parts: two cast zinc or iron flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. Torque is transmitted through the flanges mounted on both the driver and driven shafts via the sleeve. Misalignment and torsional shock loads are absorbed by shear deflection in the sleeve. The shear characteristic of the S-Flex Endurance coupling is very well suited to absorb impact loads. Combinations of flanges and sleeves can be assembled to suit your specific application, along with thirteen sizes with torque capabilities from 60 in-lbs to 72,480 in-lbs. Flanges are offered in five models which aremade from zinc or cast iron. Sleeves are available in EPDM rubber, Neoprene, or Hytrel* to address a wide variety of application requirements. Protection frommisalignment, shock, and vibration: Mechanical Power Transmission S-Flex Couplings Overview Parallel: The S-Flex coupling accepts up to 1.575 mm of parallel misalignment without wear. The flexible coupling sleeve minimizes the radial loads imposed on equipment bearings, a problem commonly associated with parallel misalignment. Axial: The S-Flex couplings can be used in applications which require a limited amount of shaft end-float without transferring thrust loads to equipment bea r i ngs . Ax i a l movemen t o f approximately 3.175 mm accepted. Angular: The flexing action of the elastomeric sleeve and the locking feature of the mat ing teeth al lows the S-Flex Coupling to effectively handle angular misalignment up to 1°. Torsional: S-Flex couplings effectively dampen torsional shock and vibration to protect connected equipment. The epdm and neoprene sleeves have torsional wind-up flexibility of 15° at their rated torque. Hytrel provides 7° wind-up.

Mechanical Power Transmission S-Flex Couplings Elastomer Designs 5 www.jbj.co.uk/s-flex-couplings.html Continue to benefit from the characteristics of the S-Flex coupling but for 3 times longer! The new EPDM coupling sleeve element lasts at least 3 times as long as the previous design, saving you valuable downtime opportunity costs and maintenance costs. The newmaterial also provides at least 30% increased torque rating and allows for product downsize in 50%of applications creating an average cost saving of 23 - 33% for sleeve element replacement. Extensive testing performed by the R&D department compared the new and improved EPDM S-Flex Endurance sleeve element material to the previous design and competitor’s similar style couplings. Ultimately the new EPDM S-Flex Endurance material met or exceeded performance in every testing category. Note the performance improvements are for the EPDMmaterial only. The Neoprene and Hytrel types remain unchanged. Elastomer Designs » Lovejoy offers flexible sleeve for S-Flex coupling in three designs: one-piece solid, one-piece split, and two-piece with retaining ring. » The one-piece split design provides solutions for applications with unique requirements where small shaft separations inhibit the installation of a one-piece solid sleeve. » Pre-moulded teeth along the diameter of the sleeve engage with teeth of the coupling flanges. » No clamps or screws are needed to connect the flanges with the flexible sleeve which securely lock together under torque for smooth transmission of power. » Torque is transmitted through shear loading of the sleeve. » All three sleeve materials are highly elastic which permits the S-Flex coupling to protect connected equipment from harmful shock loading, vibration and shaft misalignment. JE, JN, JES, JNS Sleeve Types These sleeves feature a one-piece design moulded in EPDM & Neoprene rubber. In the case of JES & JNS Types, the one-piece design is split to provide for ease of installation and removal. E, NSleeve Types These sleeves feature a two-piece design with retaining ring. The E Type is moulded in EPDM rubber and the N Type is moulded in Neoprene. The two-piece design is ideal for applications where there is difficulty in separating the shafts of the driver and driven.

Mechanical Power Transmission S-Flex Couplings Selection Process 6 S-Flex Endurance Coupling Selection Process The selection process for determining the proper S-Flex coupling requires using the charts shown on the following pages. There are three components to be selected, two flanges and one sleeve. Information necessary before a coupling can be selected: » kW/HP and RPM of Driver or running torque. » Shaft size of Driver and Driven equipment and corresponding keyways. » Application or equipment description. » Environmental conditions (i.e. extreme temperature, corrosive conditions, space limitations). List of Charts provided for Selection: » Chart 1 -Application Service Factors page 7 » Chart 2 - Sleeve Performance Data page 8 » Chart 3 - S-Flex Nominal Rated Torque Data page 8 Formulas: Nominal Torque Nm= (kWx 9550) RPM in-lb= (HP x 63025) RPM Design Torque = Nominal Torque xApplication Service Factor Steps in Selecting n S-Flex Endurance Coupling 1) Determine the Nominal Torque using the formula shown above. 2) Using theApplication Service Factor Chart 1 page 7 select the service factor which best corresponds to your application. 3) Calculate the Design Torque of your application by multiplying the Nominal Torque calculated in Step 1 by theApplication Service Factor determined in Step 2. Design Torque = Nominal Torque xApplication Service Factor. 4) Using the Sleeve Performance Data Chart 2 page 8 select the sleevematerial which best corresponds to your application. 5) Using the S-Flex Nominal Rated Torque Chart 3 page 8 locate the appropriate sleevematerial column for the sleeve selected in Step 4. 6) Scan down this column to the first entry where the Torque Value in the column is greater than or equal to the Design Torque calculated in Step 3. Refer to the maximum RPM value of the coupling size to ensure that the application requirements are met. If the maximum RPM value is less than the application requirement, S-Flex couplings are not recommended for the application. Note: If Nominal Torque is less than 1/4 of the coupling’s nominal rated torque, misalignment capacities are reduced by 1/2. Once torque value is located, refer to the corresponding coupling size in the first column of the S-Flex Nominal Rated Torque Data Chart 3 page 8. 7) Compare the application driver/driven shaft sizes to the maximum bore size available on the coupling selected. If coupling max bore is not large enough for the shaft diameter, select the next largest coupling that will accommodate the driver/driven shaft diameters. 8) Using the ItemSelection tables, find the appropriate Keyway and Bore size required and locate the Lovejoy UPC number.

Couplings » S-Flex Endurance couplings with B flanges (for use with bushings) are normally supplied with the two-piece E sleeve. » The B style flanges can be used with any of the sleeves pictured on SF-5, with the exception of the Hytrel® sleeve. » B flanges can be used in combination with S Type flanges. » Bushings have a split design that allow for a compression fit for securemounting of the flange to the shaft without set screws. » The bushing’s clamp-like fit creates a one-piece assembly to eliminate woblle, vibration and fretting corrosion. » Slightly oversized or undersized shafts can be accommodated with the same secure grip. » The design prevents potentially hazardous key drift on applications subject to pulsation or vibration. » B flanges are bored to accept a bushing accommodating many bore sizes thus reducing inventory and increasing coupling versatility. » For bushing bore information contact jbj Techniques Ltd. technical office: tel: +44 (0)1737 767493 or email: info@jbj.co.uk Cap Min Max Bore Max Bore Screw Weight L P FL T HD D Bore Standard Standard Torque Keyway Keyway 2 Size in in in in in in in in in Qty Size ft-lbs lbs JA 1.00 0.69 0.31 0.56 2.00 1.375 0.50 1.00 1.19 3 #10-1 5 0.8 1 3 SH 1.25 0.88 0.38 0.81 2.68 1.871 0.50 1.38 1.63 3 /4 - 1 /8 9 0.9 1 3 SD 1.81 1.38 0.44 1.25 3.18 2.187 0.50 1.63 1.94 3 /4 - 11 /16 9 1.6 5 SK 1.87 1.38 0.50 1.25 3.88 2.812 0.50 2.13 2.50 3 /16 - 2 15 2.8 3 SF 2.00 1.50 0.50 1.25 4.63 3.125 0.50 2.31 2.81 3 /8 - 2 30 3.9 1 3 E 2.63 1.88 0.75 1.63 6.00 3.834 0.88 2.88 3.50 3 /2 - 2 /4 60 8.5 9 5 F 3.63 2.81 0.81 2.50 6.63 4.438 1.00 3.25 3.94 3 /16 - 3 /8 75 13.9 5 1 J 4.50 3.50 1.00 3.19 7.25 5.148 1.44 3.75 4.50 3 /8 - 4 /2 135 21.6 Cap Min Max Bore Max Bore Screw Weight L P FL T HD D Bore Standard Standard Torque Keyway Keyway 2 Size mm mm mm mm mm mm mm mm mm Qty Size Nm kg JA 25.40 17.53 7.87 14.22 50.80 34.93 12.70 25.40 30.23 3 #10-1 6.78 0.363 1 3 SH 31.75 22.35 9.65 20.57 68.07 47.52 12.70 35.05 41.40 3 /4 - 1 /8 12.20 0.408 1 3 SD 45.97 35.05 11.18 31.75 80.77 55.55 12.70 41.40 49.28 3 /4 - 11 /16 12.20 0.726 5 SK 47.50 35.05 12.70 31.75 98.55 71.42 12.70 54.10 63.50 3 /16 - 2 20.34 1.270 3 SF 50.80 38.10 12.70 31.75 117.60 79.38 12.70 58.67 71.37 3 /8 - 2 40.67 1.769 1 3 E 66.80 47.75 19.05 41.40 152.40 97.38 22.35 73.15 88.90 3 /2 - 2 /4 81.35 3.856 9 5 F 92.20 71.37 20.57 63.50 168.40 112.73 25.40 82.55 100.08 3 /16 - 3 /8 101.69 6.305 5 1 J 114.30 88.90 25.40 81.03 184.15 130.76 36.58 95.25 114.30 3 /8 - 4 /2 183.04 9.798 www.jbj.co.uk/s-flex-couplings.html #DriveLineHarmony
