GENERAL
INFORMATION |
DESIGN |
CSK Series (One-Way
Bearing) The CSK model freewheel is a sprag type
clutch integrated into a 6200 series ball
bearing (except sizes 8 and 40). It provides you
with a one way clutch, and eliminates the need
for a ball bearing. It gives a high degree of
freewheeling accuracy while utilizing a minimum
of space. The CSK model freewheels can be used
in backstop, overrunning or indexing
applications. |
CSK freewheels have
the outer dimensions of type 62 ball bearings.
On the side of the balls,
sprags are mounted. The sprags and balls are
arranged in a plastic cage to hold them. The
CSK freewheels have the same characteristics as
ball bearings and additional bearing is not
necessary. |
TEMPERATURE |
The admissible
operating temperature is -40 F (-40 C) to 212 F
(+100 C). Peaks up to 248 F
(+120 C) are acceptable for short periods. |
TORQUE TRANSMISSION |
The transmission of
rated torque of these units is ensured by a
press fit 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.
One race may be glued. If both races are to be
glued, performance will be reduced or
a C3 bearing clearance will be necessary. |
MAXIMUM SPEED |
The maximum
allowable speed with standard grease is shown in
the table below. The speeds
are for operation in a clean environment within
the specified temperature range. |
