ZKLDF rotary table bearings : Detailed parameter of ZKLDF rotary table bearings.

Axial angular contact ball bearings ZKLDF460: double direction, for screw mounting, sealing shields on both sides

 ZKLDF460 rotary table bearing: ZKLDF460 are low-friction, high accuracy for very high speeds, high axial and radial loads and high demands on tilting rigidity. These bearings are particularly suitable for precision applications involving combined loads.Their preferred areas of use are bearing arrangements in rotary tables and honing heads as well as measurement and testing equipment.

Limiting speeds: ZKLDF460 rotary table bearing allow the limiting speeds given in the dimension tables. The operating temperatures occurring are heavily dependent on the environmental conditions. Calculation is possible by means of a thermal balance analysis based on frictional torque data.

Bearing preload:Once the bearings have been fitted and fully screw mounted,they are radially and axially clearance-free and preloaded.

Temperature differences:Temperature differences between the shaft and housing influence the radial bearing preload and thus the operating behaviour of the bearing arrangement. If the shaft temperature is higher than the housing temperature,
the radial preload will increase proportionally, so there will be an increase in the rolling element load, bearing friction and bearing temperature.If the shaft temperature is lower than the housing temperature,the radial preload will decrease proportionally, so the rigidity will decrease to bearing clearance and wear will increase.
