52212 Bearing Product Overview & Core Advantages
The 52212 thrust ball bearing is a metric system component engineered for demanding axial load applications. This precision bearing is characterized by its ability to accommodate high thrust loads in a single direction, making it an ideal solution for applications requiring robust axial support. Manufactured from high-grade chrome steel for both rings and balls, it ensures exceptional durability and performance. Its compact design, combined with a high axial dynamic load rating of 13,320 lbf, provides a reliable and space-efficient solution for high-stress environments.
52212 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 52 | Indicates a thrust ball bearing series with a flat housing washer and a sphered seating surface on the shaft washer. |
| 212 | Specifies the bearing dimensions: 50 mm bore, 95 mm outside diameter, and 46 mm width. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for easy re-lubrication and optimal heat dissipation in clean environments. |
52212 Bearing Structural Features & Performance Benefits
- High Load Capacity: Designed specifically for thrust loads, it features a high axial static load rating of 31,500 lbf, providing excellent resistance to deformation under heavy axial forces.
- Precision Engineering: Manufactured with tight dimensional tolerances (e.g., bore diameter tolerance of -0.012mm to 0), ensuring precise fit and reliable performance in high-precision assemblies.
- Robust Material Construction: The use of chrome steel for rings and balls, combined with a stainless steel cage, provides high strength, wear resistance, and corrosion protection, contributing to a long service life.
- Optimized Speed Performance: With a limiting speed of 2,800 rpm, the bearing is suitable for a range of moderate-speed applications. The open design and stainless steel cage contribute to stable operation at these speeds.
- Wide Temperature Range: Operates effectively within a temperature range of -30°C to 110°C, making it versatile for various industrial environments.
52212 Bearing Typical Application Areas
- Industrial Machinery: Thrust supports in heavy-duty gearboxes, vertical pumps, and industrial compressors.
- Automotive Systems: Applications in clutches, steering columns, and other assemblies requiring high axial load capacity.
- Construction Equipment: Used in crane hooks, slewing rings, and other machinery subjected to significant thrust forces.
- General Engineering: Ideal for jacks, presses, and any application where precise axial positioning and high thrust load support are critical.
