52218 Bearing Product Overview & Core Advantages
The 52218 metric thrust ball bearing is engineered for demanding applications requiring exceptional axial load capacity and precision. Designed exclusively for thrust load directions, this bearing delivers high reliability in compact installations. Its robust construction from chrome steel components ensures durability, while the open seal type facilitates optimal lubrication access. With a substantial axial static load rating of 65,250 lbf and precise dimensional tolerances, it provides stable performance in high-load, low-speed scenarios where thrust load management is critical.

| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 52 | Thrust Ball Bearing Series | Single-direction axial load design |
| 218 | Size Designation (75mm bore) | Standard metric dimension series |
| Open Seal | No integrated seals | Allows custom lubrication solutions |
52218 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The bearing's construction features precision-ground chrome steel washers and balls, enabling it to handle substantial axial dynamic loads up to 25,200 lbf and exceptional axial static loads of 65,250 lbf.
Precision Engineering: With tight dimensional tolerances (bore tolerance: -0.015mm to 0 and outside diameter tolerance: -0.025mm to 0), the bearing ensures precise fit and minimal runout in critical applications.
Durability & Corrosion Resistance: The stainless steel cage provides excellent corrosion resistance and maintains ball alignment under heavy thrust loads, while the hardened chrome steel components offer superior wear resistance.
Temperature Performance: Operating effectively within a temperature range of -30° to 110°C, the bearing maintains stable performance across diverse environmental conditions.
52218 Bearing Typical Application Areas
- Industrial Machinery: Heavy-duty presses, injection molding machines, and vertical pumps requiring high axial load capacity
- Automotive Systems: Clutch release bearings, steering column supports, and transmission components
- Construction Equipment: Crane slewing mechanisms, excavator swing drives, and hoisting systems
