| Code Segment | Technical Meaning |
|---|---|
| 1210 | Standard bearing designation indicating 50mm bore, 90mm OD |
| E | Optimized internal design for enhanced load capacity |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high speeds |
1210 ETN9 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness and stability, effectively resisting moment loads and maintaining shaft alignment under combined loading conditions.
Enhanced Load Capacity: With a dynamic load rating of 5962 lbf and static load rating of 2059 lbf, this bearing efficiently handles both radial and axial forces simultaneously.
High-Speed Performance: The TN9 nylon cage reduces friction and enables smooth operation at limiting speeds up to 10,000 rpm, while the pre-lubrication ensures consistent performance.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances, this bearing delivers consistent accuracy and long service life in precision applications.
