Product Overview: The 51256 Thrust Ball Bearing
The 51256 bearing is a high-capacity, single-direction thrust ball bearing designed to manage heavy axial loads with precision. As a key component in our Thrust Ball Bearings category, and specifically part of the 51200 Series, this bearing features principal dimensions of a 280mm bore diameter, a 380mm outer diameter, and an 80mm thickness. Its design is ideal for applications where axial forces are predominant and must be supported in a single direction. The bearing consists of a shaft washer, a housing washer, and a ball and cage assembly, which are separable, making installation and maintenance straightforward.
Manufactured to exacting industry standards, the 51256 is built for durability and reliable performance in demanding industrial environments. It is engineered to provide smooth, low-friction operation under significant axial stress, making it essential for the stability and longevity of various heavy machinery. Explore our comprehensive range of thrust bearings to find the perfect solution for your specific axial load requirements.
