The ZKLDF series thrust angular contact ball bearings are particularly suitable for applications with high speeds and long operating times. Their characteristics are high overturning rigidity, low friction, and low lubricant consumption. Thrust angular contact ball bearings are particularly suitable for precision applications that withstand combined loads. Their preferred application areas are bearing arrangements in rotating workbenches with spindle functionality, such as combination milling and turning, milling heads, grinding heads and honing heads, as well as in measuring and testing equipment.
