Product Overview: The 51138 Thrust Ball Bearing
The 51138 is a single-direction thrust ball bearing designed to manage high axial loads in one direction while operating at moderate speeds. With dimensions of 190mm bore diameter, 240mm outer diameter, and 37mm thickness, this bearing is a robust solution for applications requiring precise axial support. As a member of our 51100 Series, it is part of a comprehensive range of Thrust Ball Bearings engineered for reliability and performance. Its design consists of a shaft washer, a housing washer, and a ball and cage assembly, which are separable, simplifying the mounting and dismounting process.
This bearing is not suitable for radial loads; any radial force must be supported by a separate bearing. The 51138 is manufactured from high-quality bearing steel, ensuring excellent durability and a long service life under correct operating conditions. It is an essential component in machinery where precise axial positioning of a shaft is critical.
