Product Overview: The 51140M Thrust Ball Bearing
The 51140M is a high-capacity, single-direction thrust ball bearing, meticulously engineered to manage high axial loads in one direction. With precise dimensions of 200x250x37mm (Bore Diameter x Outer Diameter x Thickness), this bearing is a crucial component in applications requiring precise axial shaft location. Part of the esteemed 51100 Series, it features a robust machined brass cage (indicated by the 'M' suffix), which provides superior strength and performance under heavy loads and high speeds compared to standard steel cages. Its design is ideal for supporting rotating shafts and minimizing friction in purely axial-load scenarios.
As a key product in our Thrust Ball Bearings category, the 51140M is constructed with separable components—a shaft washer, a housing washer, and a ball and cage assembly. This design simplifies mounting and dismounting procedures, making it a practical choice for complex industrial machinery. Trust our commitment to quality for reliable performance in your most demanding applications.
