1212 Bearing Structural Features & Performance Benefits
Enhanced Rigidity: The double row ball bearing configuration provides superior stiffness and stability, reducing deflection under load and maintaining precision alignment.
Optimized Load Capacity: With a radial dynamic load rating of 7020 lbf and static load rating of 2745 lbf, this bearing delivers reliable performance in applications requiring substantial radial support.
High-Speed Capability: The nylon cage contributes to smooth operation at limiting speeds up to 8000 rpm, reducing friction and enabling efficient high-speed performance.
Precision Engineering: Tight dimensional tolerances on bore diameter (60 mm), outside diameter (110 mm), and width (22 mm) ensure consistent fit and performance in precision assemblies.
1212 Bearing Typical Application Areas
- Electric motors and generators requiring compact, high-speed bearings
- Industrial gearboxes and transmission systems
- Material handling equipment such as conveyor systems
- Agricultural machinery components
- General industrial machinery where reliable radial support is essential
