51109 Bearing Product Overview & Core Advantages
The 51109 metric thrust ball bearing is engineered for high-precision axial load applications. Designed exclusively for thrust load direction, this bearing delivers reliable performance in compact spaces with its slim 14mm width. Manufactured from 52100 Chrome Steel for both rings and balls, it offers excellent durability and high load capacity, supporting axial dynamic loads up to 5962 lbf. The open design ensures minimal friction, making it suitable for applications requiring precise axial positioning and smooth operation.

51109 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The bearing's construction with 52100 Chrome Steel components and precision-ground raceways enables it to handle substantial axial dynamic loads of 5962 lbf and axial static loads up to 15638 lbf, making it ideal for heavy thrust applications.
Precision Engineering: With tight dimensional tolerances (bore: -0.012mm to 0, outside diameter: -0.015mm to 0) and a stainless steel cage, the bearing maintains precise alignment and stable operation under demanding conditions.
High-Speed Capability: The open design combined with the stainless steel cage allows for limiting speeds up to 6,300 rpm, providing excellent performance in high-rotation applications.
Compact & Lightweight: With a minimal cross-section (14mm width) and weight of only 0.14 kg, this bearing offers space-saving advantages without compromising load-bearing capacity.
