52215 Bearing Product Overview & Core Advantages
The 52215 is a metric thrust ball bearing engineered for applications requiring precise axial load handling. This open-type bearing is designed to accommodate unidirectional thrust loads with high efficiency. Manufactured from high-grade chrome steel for both rings and balls, it delivers excellent durability and wear resistance. Its compact design and precise dimensional tolerances make it ideal for high-reliability installations where space is constrained and axial load capacity is critical.
52215 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 52 | Indicates a thrust ball bearing series with a flat housing washer and shaft washer. |
| 215 | Specifies the bore diameter of 60 mm and the overall dimensional series. |
| Open (Seal Type) | No seals or shields, allowing for higher speed operation and easy re-lubrication if required. |
52215 Bearing Structural Features & Performance Benefits
- High Load Capacity: The bearing's geometry and use of chrome steel components enable a high axial dynamic load rating of 14,332 lbf and an axial static load rating of 38,250 lbf, making it robust for demanding thrust applications.
- Precision & Rigidity: Manufactured with tight dimensional tolerances (bore: -0.015mm to 0) and a stainless steel cage, it ensures stable operation, minimizes vibration, and maintains alignment under load.
- Speed Performance: The open design and optimized cage contribute to a limiting speed of 2,600 rpm, suitable for various industrial speeds.
- Durability & Compliance: Constructed entirely from chrome steel (rings and balls) with a corrosion-resistant stainless steel cage. It is compliant with ROHS and REACH regulations, ensuring environmental safety.
52215 Bearing Typical Application Areas
The 52215 thrust ball bearing is commonly specified in equipment requiring management of heavy axial loads, including:
- Industrial Pumps and Compressors
- Machine Tool Spindles and positioning systems
- Automotive Steering Systems
- Heavy-Duty Gearboxes and power transmission units
- Marine Propulsion Systems
