The GFK model is a wedge-type one-way positioning clutch with dimensions identical to those of the 59 series bearings. This design features high torque at a small outer diameter. It includes grease lubrication and bearing support.
To ensure torque transmission, the installation must be tight-fitting, with an R6 tolerance on the outer ring to the machine wall, and a P5 tolerance on the inner ring's working shaft center.
Operating temperature range: -40 to 100 degrees, with a peak of +120 degrees momentarily.
