51364 Bearing Product Overview & Core Advantages
The 51364 metric thrust ball bearing is engineered for demanding applications requiring exceptional axial load capacity. Designed exclusively to handle heavy thrust loads in a single direction, this bearing features a robust construction using 52100 Chrome Steel for both rings and balls, ensuring high durability and reliability. Its significant axial static load rating of 1,112,804 lbf makes it ideal for high-stress environments where precision and long service life are critical.

51364 Bearing Structural Features & Performance Benefits
High Load Capacity: The bearing's design is optimized to support immense axial dynamic (222,561 lbf) and static loads, making it suitable for heavy-duty machinery.
Precision Ground Components: Manufactured from 52100 Chrome Steel, the rings and balls are precision-ground to ensure smooth operation and extended service life under high-stress conditions.
Chrome Steel Cage: The cage, also made from Chrome Steel, provides secure ball guidance and contributes to the bearing's structural integrity at the specified limiting speed of 0.62 x 1000 rpm.
Lubrication Requirement: As an open bearing, it requires appropriate lubrication to achieve its full performance potential and operational temperature range of -30° to 110 °C.
51364 Bearing Typical Application Areas
This thrust ball bearing is commonly specified in heavy industrial applications where substantial axial forces are present, including:
- Vertical pumps and compressors
- Heavy-duty gearboxes and power transmission systems
- Cranes and hoisting equipment
- Industrial machinery with significant axial thrust requirements
