53309 Bearing Product Overview & Core Advantages
The 53309 metric thrust ball bearing is engineered for high-precision axial load applications. Designed exclusively for thrust load direction, this bearing delivers exceptional performance in demanding environments. Its open seal type allows for optimal lubrication access while maintaining precision tolerances. Manufactured from 52100 Chrome Steel for both rings and balls with a Stainless Steel cage, it offers superior durability and corrosion resistance. The bearing's high axial dynamic load rating of 17,122 lbf and axial static load rating of 34,425 lbf make it ideal for heavy-duty thrust applications requiring reliable performance.
