51316 Bearing Product Overview & Core Advantages
The 51316 metric thrust ball bearing is engineered for demanding applications requiring high axial load capacity and precision. As a dedicated thrust bearing, it is specifically designed to accommodate heavy axial loads in a single direction while operating at moderate speeds. Its construction from high-grade 52100 Chrome Steel for rings and balls, combined with a Stainless Steel cage, ensures exceptional durability, dimensional stability, and reliable performance in industrial environments. The open seal type facilitates efficient lubrication management, making it a robust solution for high-thrust, compact assemblies.
51316 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51316 | Standard metric series designation for a thrust ball bearing with an 80mm bore and 140mm outside diameter. |
| Open (Seal Type) | No integral seals or shields. Allows for direct lubrication and is suitable for applications where external sealing is provided. |
51316 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Designed to handle significant thrust loads, with a dynamic load rating of 35,775 lbf and a static load rating of 87,750 lbf, ensuring long service life under demanding conditions.
- Precision Ground Components: The tight tolerances on bore diameter (-0.015mm to 0) and width (+0.02mm to -0.3mm) guarantee precise shaft and housing fits, contributing to high running accuracy.
- Optimized for Speed: The stainless steel cage provides strength and stability, supporting a limiting speed of 2,400 rpm for efficient operation.
- Robust Material Construction: Components made from 52100 Chrome Steel offer high hardness and wear resistance, while the cage material ensures corrosion resistance and cage integrity.
- Wide Operating Temperature: Suitable for a temperature range from -30°C to 110°C, providing flexibility for various operational environments.
