53312 Bearing Product Overview & Core Advantages
The 53312 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 assemblies. Its robust construction using 52100 Chrome Steel for rings and balls ensures durability, while the Stainless Steel cage provides stability at the specified limiting speed. This bearing is ideal for high-precision, high-stress environments where space is constrained and axial force support is paramount.

53312 Bearing Structural Features & Performance Benefits
High Axial Load Capacity: Engineered with precision-ground 52100 Chrome Steel components, this bearing achieves an axial dynamic load rating of 22,725 lbf and an axial static load rating of 50,400 lbf, making it suitable for heavy thrust applications.
Stable High-Speed Operation: The stainless steel cage ensures balanced ball guidance and reduced friction, enabling reliable performance up to the limiting speed of 3,000 rpm.
Precision Dimensions & Tolerances: Features tight dimensional tolerances (bore: -0.015mm to 0, outside diameter: -0.02mm to 0) for precise shaft and housing fits, critical for high-accuracy assemblies.
Wide Temperature Range: Operates effectively from -30°C to 110°C, accommodating various industrial environments.
53312 Bearing Typical Application Areas
- Industrial Machinery: Thrust supports in heavy-duty presses, injection molding machines, and machine tool spindles
- Automotive Systems: Clutch release bearings, steering mechanisms, and transmission components
- Power Transmission: Thrust positions in gearboxes, pulleys, and heavy-duty drives
