The UK..ZZ series is a freewheel incorporating a 62.. series bearing. The self-centring freewheels are already greaselubricated and come with dust-proof protection For the UK..ZZ model, the transmission occurs by fitting keying with n6 tolerance for shaft and N6 for the seat. 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.
