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.
