6312-2ZJEM Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway and single row design enable efficient handling of high radial loads (dynamic: 18,412 lbf, static: 11,735 lbf) while accommodating moderate axial loads.
Shielded Protection: The 2Z shielding on both sides effectively prevents the entry of contaminants, extending bearing life without significantly increasing friction, maintaining a limiting speed of 5,300 rpm.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, ensuring consistent performance and smooth operation across various applications.
Material Excellence: Constructed entirely from chrome steel (rings, balls, and cage) for superior strength, durability, and wear resistance across the operating temperature range of -30°C to 120°C.
