Characteristics Temperature Range Misalignment Shore Hardness 1 Dampening Capacity Chemical Resistance Color Angular Degree Parallel Inch SOX (NBR) Rubber – Nitrile Butadiene (Buna N) Rubber is a flexible elastomer material that is oil resistant, resembles natural rubber in resilience and elasticity and operates effectively in temperature range of -40° to 212° F (-40° to 100° C). Good resistance to oil. Standard elastomer. (Also applies to SXB Cushions.) -40° to 212° F -40° to 100° C 1° 0.015 80A HIGH GOOD BLACK URETHANE – Urethane has greater torque capability than NBR (1.5 times), provides less dampening effect, and operates at a temperature range of -30° to 160° F (-34° to 71° C). Good resistance to oil and chemicals. Not recommended for cyclic or start/stop applications. -30° to 160° F -34° to 71° C 1° 0.015 55D L050-L110 90-95A L150-L225 LOW VERY GOOD BLUE HYTREL ® – Hytrel is a flexible elastomer designed for high torque and high temperature operations. Hytrel can operate in temperatures of -60° to 250° F (-51° to 121° C) and has an excellent resistance to oil and chemicals. Not recommended for cyclic or start/stop applications. -60° to 250° F -51° to 121° C 1/2° 0.015 55D LOW EXCELLENT TAN BRONZE – Bronze is a rigid, porous oil-impregnated metal insert exclusively for slow speed (maximum 250 RPM) applications requiring high torque capabilities. Bronze operations are not affected by extreme temperatures, water, oil, or dirt. -40° to 450° F -40° to 232° C 1/2° 0.010 — NONE EXCELLENT BRONZE Spider Performance Data Chart 2 Jaw Nominal Rated Torque Data Max Bore Spider Material SOX (NBR) Torque Urethane Torque Hytrel Torque Bronze Torque Size in mm in-lbs Nm in-lbs Nm in-lbs Nm in-lbs Nm L035 0.375 9 3.5 0.4 — — — — — — L/AL050 0.625 16 26.3 3.0 39 4.5 50 5.60 50 5.60 L/AL070 0.750 19 43.2 4.9 65 7.3 114 12.90 114 12.90 L/AL075 0.875 22 90.0 10.2 135 15.3 227 25.60 227 25.60 L/AL090 1.000 25 144.0 16.3 216 24.4 401 45.30 401 45.30 L/AL095 1.125 28 194.0 21.9 291 32.9 561 63.40 561 63.40 L/AL099 1.188 30 318.0 35.9 477 53.9 792 89.50 792 89.50 L/AL100 1.375 35 417.0 47.1 626 70.7 1,134 128.00 1,134 128.00 L/AL110 1.625 42 792.0 89.5 1,188 134.0 2,268 256.00 2,268 256.00 L150 1.875 48 1,240.0 140.0 1,860 210.0 3,708 419.00 3,706 419.00 AL150 1.875 48 1,450.0 163.8 — — — — — — L190 2.125 55 1,728.0 195.0 2,592 293.0 4,680 529.00 4,680 529.00 L225 2.625 65 2,340.0 264.0 3,510 397.0 6,228 704.00 6,228 704.00 L276 2.875 73 4,716.0 533.0 — — — — 12,500 1 412.00 C226 2.500 64 2,988.0 338.0 — — 5,940 671.00 5,940 671.00 C276 2.875 73 4,716.0 533.0 — — 9,432 1 066.00 — — C280 3.000 76 7,560.0 854.0 — — 13,866 1 567.00 — — C285 4.000 102 9,182.0 1 038.0 — — 16,680 1 882.00 — — C295 3.500 89 11,340.0 1 281.0 — — 22,680 2 563.00 22,680 2 563.00 C2955 4.000 102 18,900.0 2 136.0 — — 37,800 4 271.00 37,800 4 271.00 H3067 4.500 114 33,395.0 3 774.0 — — 47,196 5 333.00 47,196 5 333.00 H3567 5.000 127 46,632.0 5 269.0 — — 63,000 7 119.00 63,000 7 119.00 H3667 5.629 143 64,812.0 7 323.0 — — 88,200 9 966.00 88,200 9 966.00 H4067 6.250 159 88,224.0 9 969.0 — — 126,000 14 237.00 126,000 14 237.00 H4567 7.000 178 119,700.0 13 525.0 — — 170,000 19 209.00 170,000 19 209.00 Chart 3 Note: Bronze has a maximum RPM capability of 250 RPM.
