1209-K-TVH Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and can handle significant combined radial and axial loads simultaneously, making it suitable for applications with complex loading conditions.
Precision Tapered Bore: The 1:12 tapered bore ensures secure mounting on tapered shafts, providing excellent concentricity and minimizing vibration during high-speed operation.
High-Speed Capability: The lightweight nylon cage (TVH) reduces centrifugal forces and enables limiting speeds up to 11,000 rpm, while the CN radial clearance ensures optimal performance across various operating conditions.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, this bearing offers excellent wear resistance and durability under demanding conditions.
