Product Description

GFK Series GFK35 Sprag Type Freewheel One Way Sprag Clutch Bearing

Brief Introduction of GFK One Way Clutch Bearing

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. Whatever the lubrication type, seals should be provided.

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℃ to +100°C. Peaks up to +120℃ are acceptable for short periods.
