52311 Bearing Product Overview & Core Advantages
The 52311 metric thrust ball bearing is engineered for high-capacity axial load applications requiring precise dimensional control. Manufactured from chrome steel with a stainless steel cage, this open-type bearing delivers reliable performance in demanding conditions. Its key advantage lies in its ability to accommodate heavy thrust loads in one direction while maintaining exceptional dimensional stability due to its tight bore and outside diameter tolerances. This makes it an ideal choice for applications where high rigidity and axial load capacity are critical.
52311 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 52311 | Standard metric designation for a thrust ball bearing with a 45mm bore diameter. |
| Open (Seal Type) | No integral seals or shields, allowing for higher limiting speeds and custom lubrication schemes. |
52311 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered to support substantial dynamic (22,725 lbf) and static (50,400 lbf) thrust loads, ensuring durability under heavy axial forces.
- Precision Ground Components: Tight tolerances on the bore diameter and outside diameter enable precise shaft and housing fits, critical for high-rigidity applications.
- Optimized for Speed: The stainless steel cage and open design contribute to a limiting speed of 2,200 rpm, suitable for various industrial speeds.
- Robust Material Construction: Chrome steel rings and balls provide high wear resistance and fatigue life, while the stainless steel cage offers corrosion resistance and cage integrity.
- Wide Operating Temperature Range: Performance is maintained from -30°C to 110°C, accommodating diverse environmental conditions.
