51310 Bearing Product Overview & Core Advantages
The 51310 is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity and precision performance. This thrust bearing is designed to accommodate unidirectional axial loads exclusively, making it an ideal solution for scenarios with heavy thrust forces. Manufactured from 52100 Chrome Steel for both rings and balls, it ensures excellent durability and wear resistance. Its compact design, combined with a high axial dynamic load rating and strict dimensional tolerances, makes it suitable for high-reliability and precision assemblies.
51310 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 51310 | Basic Model Number | Indicates a metric series, single-direction thrust ball bearing with a 50mm bore and 95mm OD. |
| Open (Seal Type) | No Seals or Shields | Optimized for high-speed operation and allows for direct re-lubrication, but requires a clean operating environment. |
51310 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's geometry and use of chrome steel components enable it to handle significant axial dynamic load ratings of 18428 lbf and axial static load ratings of 38250 lbf, providing robust performance under heavy thrust.
- Precision and Rigidity: Manufactured with tight dimensional tolerances on the bore diameter and outside diameter, it ensures precise shaft and housing fits, contributing to system stability and reduced vibration.
- High-Speed Capability: The stainless steel cage provides low friction and high strength, supporting the bearing's limiting speed of 3,600 rpm.
- Durability and Compliance: Constructed entirely from 52100 Chrome Steel for rings and balls, it offers high hardness and corrosion resistance. The bearing is also ROHS and REACH compliant, meeting modern environmental standards.
51310 Bearing Typical Application Areas
This thrust ball bearing is commonly specified in applications requiring management of heavy axial loads, including:
- Automotive: Thrust assemblies in transmissions and steering systems.
- Industrial Machinery: Vertical pumps, heavy-duty gearboxes, and machine tool spindles.
- Power Transmission: Applications within clutches and heavy-duty fans.
- General Engineering: Any rotating assembly where precise axial positioning and high thrust capacity are critical.
