The 812/500-M Cylindrical roller thrust bearings mainly consist of a shaft ring, a housing ring, cylindrical rollers, and a cage assembly. The rollers are arranged radially, forming a line contact load-bearing structure.
The advantages of cylindrical roller thrust bearings include extremely high axial load capacity, excellent rigidity, and a low coefficient of friction. Optimized roller end faces and flanges can accommodate slight eccentricity and impact loads, while also featuring a compact structure and high rotational accuracy.
