The ball cages are made from plastic, permissible operating temperature 120 °C (continuous operation).
On request the bearings can also be supplied with less stringent tolerances (type ZKLF...PE)
1) Contact angle α = 60°.
2) Hole diameter tolerance as of d = 60 mm d-0.008
3) Outer diameter tolerance as of d = 60 mm D-0.015
4) Bearing friction torque with gap seal (.2Z). With seal disc (.2RS) approx. 2 × MRL .
5) Refer to catalogue for table of dimensions. Lock nuts are not supplied; order separately!
6) Minimum diameter required of installation surface. If these diameters are not reached, the diameters D1 and d1 should be noted.
