| TN9 | Nylon cage (polyamide) providing excellent high-speed performance and reduced friction |
11212 TN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial stiffness and increased load carrying capacity, making it suitable for applications with substantial radial forces. With a dynamic load rating of 7020 lbf and static load rating of 2745 lbf, this bearing delivers reliable performance under demanding conditions.
High-Speed Performance: The TN9 nylon cage ensures optimal performance at high rotational speeds, contributing to the bearing's limiting speed of 3,400 rpm. The lightweight cage design reduces centrifugal forces and maintains stability during high-speed operation.
Material Excellence: Constructed from chrome steel for both rings and balls, the bearing offers excellent wear resistance and durability. The combination of premium materials and precision manufacturing ensures consistent performance and extended service life.
Temperature Compatibility: Operating effectively within a temperature range of -30°C to 110°C, this bearing maintains performance across various environmental conditions while the pre-lubrication provides initial protection and smooth operation.
