51105 NTN 25x42x11 Thrust Ball Bearing

Axial load bearing for industrial machinery

Reliable thrust bearing for bearing units and housings

Main Description

The 51105 NTN 25x42x11 thrust ball bearing is a precision rolling element designed exclusively for axial load transmission in one direction. This type of ball bearing is widely used in industrial systems where controlled axial force, stable positioning and repeatable performance are required. It is not intended for radial loads, making it ideal for dedicated thrust applications.

The bearing consists of two hardened thrust washers and a ball-and-cage assembly, ensuring uniform load distribution and low friction during operation. This construction delivers high durability, smooth axial motion and consistent performance under continuous working conditions. The precision geometry supports reliable integration into a bearing housing or as part of a complete bearing unit.

With compact dimensions of 25x42x11 mm, the 51105 thrust bearing is commonly applied in gearboxes, machine tools, industrial drives, presses and mechanical assemblies where axial forces must be absorbed without compromising efficiency. Its design allows stable operation at moderate rotational speeds while maintaining accurate axial guidance.

Manufactured to strict quality standards, the NTN thrust ball bearing offers excellent wear resistance and dimensional stability. For B2B customers, it represents a dependable component for production machinery, maintenance operations and OEM solutions where long service life and predictable behavior are critical.
