FAG ZKLN series super precision thrust bearings are double-acting units that handle axial loads in both directions along with moderate radial forces. They suit machine tool spindles, rotary tables and positioning systems where accuracy and rigidity matter. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America.

The part number itself tells you the size and features. Take ZKLN0619-2Z-XL: ZKLN identifies a double-acting super precision thrust bearing, the first two digits give the shaft diameter and the next two the outside diameter. The 2Z suffix means protective seals on both sides, and XL places it in the X-life range with optimized surfaces. The same logic applies to ZKLN1034-2Z-XL and ZKLN2052-2Z-XL.

You will find these bearings in machine tools, measuring equipment, robotics, medical devices and optical systems. Typical installations include milling and grinding spindles, machining centers, coordinate tables and linear actuators. Their capacity for combined loads and high rigidity make them a fit for assemblies that need repeatability and low friction.

Selection depends on the axial and radial load, the rotation speed and the operating environment. The 2Z seal keeps contaminants out and lubrication in, but a very aggressive setting may call for extra sealing. Mounting requires precise alignment between shaft and housing, suitable tools and the specified tightening torques. Use the grease recommended by the manufacturer to reach the expected service life.

Equivalent super precision thrust bearings from other brands may carry different designations, even though main dimensions and load capacities are usually standardized. Always confirm the complete part number and technical specifications before replacing a bearing. Our team can advise on interchangeability within our catalog.
