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.

Operating temperature range : -20°C to +100°C. Peaks up to +120°C are acceptable for short periods. Please contact us for higher temperatures.

Features of one way clutch bearing:

A Cam Clutch mechanism integrated into a ball bearing cassette(#62 type)!

1)Compact Design

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.

2)Reduced Cost

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.

5)Cam design

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.

Applications of one way clutch bearing:

Air cleaning plants; Agricultural machines; Buchet elevators; Compressors; Conveyors; Cranes and hoists; Dry cleaning machinery; Duplicator equipment; Fish net machines; Heat-treatment furnaces; Induced draft fans; Multi-states conveyors; Packaging machinery; Printing machinery; Pumps; Punch presses and feeders; Power plants; Refinery equipment; Speed reducers; Standby power units; Textile looms; Two-speed grinders; Two-speed shiftovers; Washing machines; Wire winding machinery.
