| Code Segment | Technical Meaning |
|---|---|
| 1205 | Basic bearing designation indicating metric series with 25mm bore diameter |
| TN | Nylon (polyamide) cage, injection molded design for high-speed performance and reduced friction |
1205TN Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides enhanced stiffness and can accommodate significant combined loads, including radial loads up to 3218 lbf dynamic rating and bidirectional axial loads simultaneously.
High-Speed Capability: The TN nylon cage ensures excellent performance at limiting speeds up to 18,000 rpm, offering reduced weight and smoother operation compared to metal cages.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) and CN radial internal clearance for consistent precision bearing performance.
Temperature Resilience: Operating temperature range of -30°C to 110°C ensures reliable performance across diverse industrial environments.
