YRTS260P4 260*385*55mm ZKLDF Rotary Table Bearing

The features of ZKLDF series rotary table bearing ZKLDF100 :

ZKLDF series turnable bearing has the characteristics of low friction, high rotation accuracy, high limit speed, etc. It can withstand higher axial and radial loads and has higher inclined stiffness. These bearings are suitable for axial and radial combined loads and precision applications, and are widely used in machine tool rotary tables, grinding heads, and various test equipment.

Limiting speeds: ZKLDF series rotary table bearing ZKLDF100 allows the limiting speed given in the dimension tables. The operating temperature that occurs depends largely on the environmental conditions. The calculation can be performed by thermal balance analysis based on friction torque data.

Bearing preload: After the bearings are installed and completely fixed with screws, they are radially and axially clearance-free and preloaded. 

Temperature differences: The temperature difference between the shaft and the bearing housing will affect the preload of the radial bearing, which in turn will affect the working performance of the bearing device. If the shaft temperature is higher than the housing temperature, the radial preload will increase proportionally, so the load on rolling elements, bearing friction and bearing temperature will increase. If the shaft temperature is lower than the housing temperature, the radial preload will decrease proportionally, so rigidity will reduce, and bearing clearance and wear will increase.KLDF angular contact thrust bearings

 ZKLDF Rotary Table Bearing: Axial/radial bearings and axial angular contact ball bearings are ready-to-fit high precision bearings for high precision applications with combined loads. They can support radial loads and axial loads from both sides as well as tilting moments and are particularly suitable for bearing arrangements with high requirements for running accuracy, for example in rotary tables, face plates, milling heads and reversible clamps.Due to the fixing holes in the bearing rings, the units are very easy to fit. The bearings are radially and axially preliminary load after fitting.

ZKLDF 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.
