6309NRJEM Bearing Product Overview & Core Advantages
The 6309NRJEM is a single row deep groove ball bearing designed for high-performance industrial applications requiring reliable radial load capacity and precise operation. This metric bearing features a snap ring groove on its outer ring, enabling secure axial positioning within housings without requiring complex machining. Manufactured to ABEC 1 | ISO P0 tolerance standards with CN radial clearance, it delivers consistent performance in general precision applications. The open design allows for versatile lubrication options while the chrome steel construction ensures durability across a wide temperature range (-30° to 120°C).

6309NRJEM Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry provides excellent radial load capacity (11,915 lbf dynamic / 7,194 lbf static) while accommodating moderate axial loads in both directions.
Snap Ring Integration: The outer ring snap ring groove eliminates the need for additional components, reducing assembly complexity and providing reliable axial location in housing bores.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with CN radial clearance, ensuring consistent performance and smooth operation in general industrial applications.
Material Excellence: Constructed entirely from chrome steel (rings, balls, and cage) for superior strength, wear resistance, and consistent performance across the specified temperature range.
High-Speed Capability: With a limiting speed of 6,700 rpm, this bearing is suitable for various medium to high-speed applications when properly lubricated.
