x = 9 N
l = 13.5 mm (for standard shafts on GCLS according to protection class IP20)
The following conditions must be observed:
• For drives with a chain drive system, timing belt system etc., the permissible radial force F
max
must not be
exceeded.
• In protective housings type MH and MxZ, a grooved ball bearing is mounted additionally to the sleeve
bearing. When using these housings, the permissible F
max
value can be doubled.
• Impact-like axial forces are not permitted on the drive shaft.
