1312KJ Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact configuration provides superior stiffness and can handle significant combined radial and axial loads (13,162 lbf dynamic rating). This makes it suitable for applications with complex loading conditions.
Precision Tapered Bore: The 1:12 tapered bore ensures precise interference fit on the shaft, eliminating creep and maintaining positional accuracy under heavy loads and high speeds.
Optimized Internal Clearance: Standard CN radial internal clearance provides optimal performance balance for most industrial applications, ensuring smooth operation and extended service life.
High-Speed Capability: With a limiting speed of 6,300 rpm and steel cage construction, this bearing maintains stability and reliability at elevated rotational speeds.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance in demanding environments.
