6310-2RSNRJEM Bearing Product Overview & Core Advantages
The 6310-2RSNRJEM is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric series bearing features a snap ring groove on its outer ring for secure axial location and comes pre-sealed for enhanced protection. Its key advantages include robust radial load capacity (13,938 lbf dynamic rating), consistent operation within a wide temperature range (-30° to 120°C), and compliance with ABEC 1 | ISO P0 precision standards. The combination of a snap ring and integral seals makes it an excellent choice for applications requiring simplified housing design and long-term, maintenance-free operation.

6310-2RSNRJEM Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The single row design with deep raceway grooves enables excellent radial load capacity and moderate axial loads in both directions.
Integrated Sealing Solution: The -2RS designation indicates dual-contact rubber seals that effectively retain lubricant and exclude contaminants like dust and moisture, significantly extending bearing service life.
Secure Axial Location: The snap ring groove (NR) and supplied snap ring (J) allow for simplified and secure axial positioning within the housing, reducing design complexity and assembly time.
Electrical Insulation: The EM coating provides protection against damage from stray electrical currents, preventing fluting and premature failure—a critical feature in electric motors and generator applications.
High-Quality Materials: Manufactured from chrome steel for rings, balls, and cage, ensuring high strength, durability, and consistent performance under the specified temperature range.
6310-2RSNRJEM Bearing Typical Application Areas
- Electric Motors & Generators: Ideal for use as end-shield or fan-end bearings, benefiting from the electrical insulation and sealed design.
- Industrial Gearboxes: Suitable for output shafts and intermediate shafts where radial loads dominate and secure axial location is required.
- Material Handling Equipment: Conveyor rollers and pulley systems where the sealed, snap-ring design simplifies maintenance.
- Agricultural Machinery: Pumps, fans, and auxiliary drives operating in harsh, dusty environments.
- General Industrial Machinery: A versatile choice for pumps, compressors, and blowers requiring a reliable, pre-lubricated, and easily mounted bearing solution.
