CSK CLUTH is a sprag type freewheel integrated into a 62
series ball bearing (except sizes 8 and 40). It is bearing
supported, delivered grease lubricated and protected
against dust of more than 0,3 mm. The use of additional
“nylos” type seals is recommended especially when the
working temperature exceeds 50ÅãC. Oil bath lubrication is
also possible.
All the CSK versions are equipped with “formchromed”
sprags. This process increases several times the
overrunning life time. Torque transmission is ensured
by a press fit assembly into a rigid outer housing with N6
tolerance, and onto a shaft with n6 tolerance. The initial
bearing radial clearance is set at C5, and is reduced if
using the press fit as specified.
Please contact us when either the ambient or the
operating temperature is not within the range +5ÅãC to
+60ÅãC. CSK..2RS is 5 mm wider but is equiped with lip
seals to be water splash resistant.
