For the UK models, the transmission occurs by fitting keying with n6 tolerance for each shaft and N6 tolerance for the seat.
The UKC models are 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.
The UKCC model is equipped with a keyway on the inner and outer race, the tolerances are h6 for the shaft and H6 for the rigid seat.
The UK Series is built with a C5 clearance that turns into a normal clearance after keying. The races can be glued to the shaft and the seat. In this case, the clearance remains C5.
The working temperature is between -10°C and +60°C for different values please contact our technical department!
