Type GFK is a sprag type
freewheel integrated into a 59.. series ball bearing.
This design provides high
torque capacity for minimal outside diameter.
It is a bearing supported
type, delivered grease lubricated.
Oil bath lubrication is
also possible if the original grease is first removed by flushing the freewheel
with a suitable solvent.
Whatever the lubrication
type, seals should be provided, as illustrated on the next page.
Torque transmission must
be ensured by a press fit assembly into a rigid outer housing with R6
tolerance, and onto a shaft with p5 tolerance.
Initial radial clearance
has been provided to take into account this heavy press fit.
range : -20°C to +100°C. Peaks up to +120°C are acceptable for short periods.

one way clutch bearing:
A Cam Clutch mechanism integrated into a ball
bearing cassette(#62 type)!
More efficient use of space with a
one-way clutch and ball bearings all in a compact unit within the same
dimensions as the bearings itself.
Keyless installation by just pressing the
clutch into housings or onto shafts. There is no need to machine or harden the
shaft as with conventional shell-type roller clutches.
3)Increased Torque Capacity
Many cam are installed between the bearings
inner and outer race to allow a significantly increased torque capacity
compared to shell-type roller clutches.
4)Full cam complement
The full complement of cams provide the
maximum number of load transmitting members per given diameter, The result is a
greater torque capacity size-for-size than other clutches.
Precision formed cams made of a special alloy
steel provide extra long wear and fatigue life.
6)High quality components
The clutch races are made of high-quality
alloy steel with high surface hardness and core toughness. The races are
precision groud, provide excellent concentricity and surface finish to obtain
accurate cam rotation.
The major parts of the cam clutch are the
cams, inner race, out race, springs and bearings. Each of these parts play an
important role in the function of the cam clutch. All parts are made of
carefully selected materials, have undergone appropriate heat treatment, and
have passed strict quality control checks.
