1208TN Bearing Structural Features & Performance Benefits
Double Row Design: The two-row ball arrangement provides enhanced rigidity and moment load capacity compared to single row bearings, making it suitable for applications with significant radial and axial load combinations.
Precision Components: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.012mm to 0, OD: -0.013mm to 0) ensuring consistent performance and extended service life.
High-Speed Capability: The TN nylon cage enables smooth operation at limiting speeds up to 11,000 rpm, reducing centrifugal forces and maintaining stability during high-speed rotation.
Optimized Load Distribution: With a radial dynamic load rating of 4,478 lbf and static load rating of 1,564 lbf, this bearing effectively handles substantial combined loads in demanding applications.
Standard Internal Clearance: CN radial internal clearance provides optimal performance for most industrial applications under normal operating conditions.
