6312 JEM Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry enables efficient handling of high radial loads (dynamic: 18,412 lbf / static: 11,735 lbf) while accommodating moderate axial loads in both directions.
High-Speed Capability: With a limiting speed of 5,300 rpm, this bearing is engineered for applications requiring rapid rotation. The precision-ground chrome steel components and optimized cage design minimize friction and heat generation.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class with tight dimensional control (bore: -0.015mm to 0), ensuring smooth operation and reduced vibration in precision machinery.
Versatile Application Range: The open construction and wide temperature range (-30°C to 120°C) make it suitable for various operating environments and lubrication systems.
