6310-2RS1/LT20 Bearing Product Overview & Core Advantages
The 6310-2RS1 is a single row deep groove ball bearing designed for reliable performance in demanding applications. Its key advantage lies in its sealed construction (2RS1), which provides effective protection against contaminants while retaining lubrication. This bearing excels at handling primarily radial loads and offers a robust, cost-effective solution with a standard ABEC 1 (ISO P0) tolerance. The combination of chrome steel components and integrated sealing makes it a durable, low-maintenance choice for a wide range of industrial machinery.
Model Code Breakdown
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6310 | Basic Bearing Number | Denotes a metric single row deep groove ball bearing with a 50 mm bore, 110 mm OD, and 27 mm width. |
| 2RS1 | Sealing Type | Indicates contact seals on both sides, made of NBR rubber. This provides superior contaminant exclusion compared to shielded or open bearings. |
6310-2RS1/LT20 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from high-carbon chrome steel for rings, balls, and cage, ensuring high strength and durability under load.
- Effective Sealing: The 2RS1 double lip seals effectively prevent the ingress of dust, dirt, and moisture, while retaining lubricant. This significantly extends bearing service life and enables operation in less-than-ideal environments.
- Radial Load Capacity: The deep groove raceway and continuous shoulder design is optimized for high radial dynamic load ratings (13,938 lbf), making it suitable for applications with significant radial forces.
- Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, offering a balance of performance, reliability, and cost for general industrial use.
6310-2RS1/LT20 Bearing Typical Application Areas
This versatile sealed bearing is commonly specified in:
- Electric Motors and Gearboxes
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
- General Machinery requiring reliable, sealed bearing units
