Supplied with DIN 931/933 10.9 screws except for SIT-LOCK® 11S 12.9 which is supplied with DIN 912 12.9 screws. SIT-LOCK® 11 versions SIT-LOCK® 11S ~ standard series (recommended version). SIT-LOCK® 11S 12.9 ~ (version with DIN 912/933 12.9 screws). SIT-LOCK® 11H ~ heavy duty series (for very high torques). SIT-LOCK® 11L ~ light series (for low torques). Coupling tolerances diameter d h8 diameter d tolerances: w from 10 to 30 mm H6 / j6 from 31 to 50 mm H6 / h6 from 51 to 80 mm H6 / g6 from 81 to 1000 mm H7 / g6 Do not use molybdenum disulphide-based oils or greases that reduce the coefficient of friction . The values in the table are calculated with 0.12 m m The table shows the Mt - Fax - Pw and Pn values for applications where the hub axially locks a part. For applications that do not require this function, SIT-LOCK® 5A or 5B is recommended. Surface finish Normal surface finish is sufficient. The following values are recommended: R ≤ 3.2 μm - R ≤ 16 μm a t Applications with bending moment For applications where there is a bending moment M while a torque M r is also transmitted, check that the M value is less than the transmissible torque f t t tot indicated in the table. Applying a bending moment 30% greater than the M value indicated in the table is not advised. t Recommended materials for shaft d and hub d w The pressure generated on diameter d generates a pressure P on the diameter d , which allows the transmission of the torque M indicated in the table. The w w t pressure generated on the diameter d is distributed over the surface of the diameter d at an angle of approximately 16°- 20°. The pressure P can be w w determined using the following formula: 2 Shaft and hub materials with a σ ≥ 360 N/mm are recommended.
