6312-2RS1/LT20 Bearing Product Overview & Core Advantages
The 6312-2RS1 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Engineered with metric dimensions and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers robust performance for primarily radial loads. Its key advantage lies in its sealed construction (2RS1), which provides superior protection against contamination, making it ideal for applications where maintenance access is limited. The combination of high-quality chrome steel components ensures durability and a long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing series; indicates a medium width series deep groove ball bearing with a 60mm bore and 130mm outside diameter. |
| 2RS1 | Contact seals on both sides, made from Nitrile Rubber (NBR). This provides effective protection against dust and moisture ingress. |
6312-2RS1/LT20 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals effectively shield the internal components from contaminants, significantly enhancing bearing life in dirty or humid environments. This creates a maintenance-free solution for the duration of the lubricant's life.
- High Load Capacity: With a dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, this bearing is built to handle significant radial loads, ensuring reliable operation under strenuous conditions.
- Optimized for Standard Applications: Featuring a standard CN radial internal clearance and a limiting speed of 5,300 rpm, it is well-suited for a wide range of industrial machinery operating at common speeds.
- Durable Construction: All critical components—rings, balls, and cage—are manufactured from high-carbon chrome steel, providing excellent wear resistance and overall mechanical strength.
6312-2RS1/LT20 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable, sealed bearing solutions.
