Introduction
The UKC..ZZ model is equipped with a keyway on the inner race and should be fitted on k6 tolerance shafts. Seat fitting must be carried out with n6 keying tolerance.
Types UKC..ZZ and UKCC..ZZ are sprag type freewheels integrated into 62.. series ball bearings (except size 40).They are bearing supported, delivered grease lubricated and protected against dust of more than 0,3 mm.
The use of additional “nylos” type seals is recommen-ded especially when the working temperature exceeds 50°C. Oil bath lubrication is also possible.
In addition to the basic UK..ZZ model, type UKC..ZZ features a keyway on the inner race. For this reason it can be keyed to a shaft to k6 tolerance. The outer race must still be pressed into a rigid housing to N6 tolerance.
UKCC..ZZ features a keyway on both the inner and outer race. The recommended mounting tolerances are h6 on the shaft and H6 in a rigid housing. Please contact us when either the ambient or the operating temperature is not within the range +5°C to +60°C.
