NSK 1 Row Thrust Ball Bearing, 25 mm Inside Diameter, 42 mm Outside Diameter, 11 mm Race Width, Steel Balls and Cage 51105 N

NSK 51105 N is a high-quality 1 Row Thrust Ball Bearing with 25 mm inside diameter, 42 mm outside diameter, and 11 mm race width. It features steel balls and a steel cage, designed specifically for unidirectional axial thrust loads.

This bearing is engineered for precision and durability, providing a static load rating of 37 kN and a dynamic load rating of 19.7 kN. It has an internal clearance class of CN and a limiting speed of 7100 RPM, ideal for demanding industrial applications.

The bearing is part of NSK’s 1 Extra Light Thrust series, characterized by a parallel bore type and plain raceway, optimized for thrust ball bearing performance.

These thrust ball bearings are used widely across aerospace, marine, and automotive industries for applications such as gearboxes, clutches, steering mechanisms, and vertical shaft bearings. They help reduce axial loads and noise, thereby improving mechanical efficiency.

NSK thrust bearings are not suitable for radial loads as applying radial loads may lead to misalignment and bearing damage. They are supplied as three-part assemblies consisting of two grooved outer raceways and a caged ball set.

The bearing uses steel balls and cages for robustness and longevity. It provides reliable service in high-speed rotational environments up to 7100 RPM. Axial thrust loads up to 37 kN (static) and 19.7 kN (dynamic) can be accommodated.

Available as single-row configuration for compact mechanical assemblies. Designed for use in industrial, automotive, aerospace, marine, and mechanical engineering domains. Set contains one NSK 51105 N thrust ball bearing.
