Feature
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.
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.
