| Model Segment | Technical Meaning |
|---|---|
| 6310 | Standard bearing series designation indicating dimensions: 50mm bore, 110mm OD, 27mm width. |
| NR | Specifies a snap ring groove on the outer ring with a snap ring fitted (supplied). |
6310 NR Bearing Structural Features & Performance Benefits
- Snap Ring Location: The integrated snap ring (outer diameter: 116.6mm) enables positive axial location, eliminating the need for complex housing shoulders and reducing assembly time and cost.
- High Load Capacity: With a dynamic load rating of 14,613 lbf and a static load rating of 8,543 lbf, this bearing is engineered to handle significant radial loads in continuous operation.
- Robust Construction: Components made from chrome steel (rings and balls) and a stainless steel cage ensure high durability, corrosion resistance, and long service life.
- Open Design & Versatility: The open seal type allows for easy re-lubrication and is suitable for a wide operating temperature range from -30°C to 120°C.
- Precision Performance: Manufactured to P0 tolerance class, it guarantees consistent running accuracy and smooth operation at limiting speeds up to 8,500 rpm.
6310 NR Bearing Typical Application Areas
This bearing is ideally suited for applications where secure axial positioning and high radial load capacity are critical. Common uses include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
