3310 DNRCBM Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row configuration provides superior stiffness compared to single row bearings, making it ideal for applications requiring minimal deflection under load. The optimized contact angle ensures stable operation even under heavy combined loads.
Enhanced Load Capacity: With a radial dynamic load rating of 18,428 lbf and static load rating of 15,638 lbf, this bearing can handle significant radial and axial forces simultaneously. The precision ground raceways distribute stress evenly for extended service life.
High-Speed Performance: The brass cage (M designation) enables stable operation at limiting speeds up to 5,600 rpm. The optimized internal geometry minimizes friction and heat generation, making it suitable for high-speed applications.
Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional controls (bore tolerance: -0.01mm to 0), this bearing ensures precise rotational accuracy and reliable performance in precision machinery.
3310 DNRCBM Bearing Typical Application Areas
- Machine Tool Spindles: Precision machining centers requiring high rigidity and accuracy
- Industrial Gearboxes: Power transmission systems needing reliable bearing performance
- Pump Systems: Centrifugal and rotary pumps handling combined radial and axial loads
