| A | Contact Angle Optimization | Enhanced axial load capacity and stiffness characteristics |
| TN9 | Nylon Cage Design | Lightweight construction for high-speed operation, reduced friction, and excellent acceleration characteristics |
4215 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, making it ideal for applications requiring minimal deflection under heavy combined loads.
Enhanced Load Capacity: With a dynamic load rating of 16,380 lbf and static load rating of 18,000 lbf, this bearing delivers reliable performance in demanding applications.
High-Speed Capability: The TN9 nylon cage enables smooth operation at limiting speeds up to 7,500 rpm, while the optimized internal geometry reduces heat generation and power loss.
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0) of 0.01-0.03mm, ensuring consistent performance and extended service life.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability across the operating temperature range of -30°C to 110°C.
