Product Overview and Core Advantages
The 51305 is a metric thrust ball bearing engineered for applications requiring precise axial load handling. Designed exclusively for thrust load direction, this bearing delivers reliable performance in high-demand environments. Its compact design, featuring a 25 mm bore and 18 mm width, makes it ideal for space-constrained assemblies. Manufactured from 52100 Chrome Steel for both rings and balls, it ensures excellent durability and wear resistance. The bearing's high axial dynamic load rating of 7762 lbf and axial static load rating of 13500 lbf make it suitable for heavy-duty thrust applications.
