51116 Bearing Product Overview & Core Advantages
The 51116 metric thrust ball bearing is engineered for applications requiring high-precision axial load capacity in a compact design. Manufactured from 52100 Chrome Steel for both rings and balls, it delivers exceptional durability and wear resistance. This single-direction thrust bearing is characterized by its ability to handle significant dynamic and static axial loads (10,102 lbf and 31,500 lbf respectively) while maintaining a low profile with a 19 mm width. Its open design facilitates efficient lubrication and cooling, making it ideal for high-speed operations up to 4,300 rpm. Compliant with ROHS and REACH standards, it ensures reliability in demanding industrial environments.

51116 Bearing Structural Features & Performance Benefits
- High Load Capacity: The precision-ground raceways and 52100 Chrome Steel construction enable handling of substantial axial dynamic loads (10,102 lbf) and axial static loads (31,500 lbf), providing reliable performance under heavy thrust conditions.
- High-Speed Capability: With a limiting speed of 4,300 rpm and a stainless steel cage for reduced friction and weight, this bearing supports efficient high-speed operation.
- Precision Tolerances: Tight dimensional tolerances on bore (-0.015mm to 0) and outside diameter (-0.02mm to 0) ensure precise fit and alignment, critical for high-precision applications.
- Thermal Stability: Operating temperature range of -30°C to 110°C combined with open design allows for effective heat management in various environments.
- Compact & Lightweight: With a width of just 19 mm and weight of 0.42 kg, it offers space-saving solutions without compromising load-bearing performance.
