Product Overview: The N 222 Cylindrical Roller Bearing
The N 222 is a high-capacity cylindrical roller bearing with principal dimensions of 110x200x38mm. As a key component in our N 200 Series, this bearing is engineered to handle substantial radial loads at high speeds. It belongs to the broader family of Cylindrical Roller Bearings, which are distinguished by their line contact between the rolling elements and raceways, providing superior load-carrying capability compared to ball bearings of similar size. The 'N' designation signifies a specific internal design where the inner ring has two integral flanges and the outer ring is flangeless. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions in various industrial applications.
Key Features of the N 222 Bearing
- High Radial Load Capacity: The line contact geometry between rollers and raceways enables the bearing to support heavy radial loads.
- Axial Displacement Accommodation: The 'N' type design allows for axial movement of the shaft in both directions, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The outer ring is separable from the inner ring and roller assembly, simplifying the mounting and dismounting process.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, making it suitable for high-speed rotational applications.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and long service life.
- High Stiffness: Provides rigid support to the shaft, minimizing deflection under load and ensuring precise operation.
Common Applications for N 222 Bearings
- Industrial Gearboxes: Used as non-locating bearings to support gear shafts and manage heavy radial forces.
- Large Electric Motors: Provides robust support for motor shafts, especially on the non-locating end.
- Pumps and Compressors: Ensures reliable operation of rotating components under demanding conditions.
- Rolling Mills: Employed in steel and metal processing equipment where high loads and speeds are prevalent.
- Construction Machinery: Found in heavy equipment like excavators, cranes, and earthmovers.
- Machine Tool Spindles: Offers the rigidity and precision required for high-performance machining centers.
- Vibrating Screens and Crushers: Withstands the shock loads and vibrations common in mining and aggregate industries.
Benefits of Using the N 222 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy radial loads reduces the risk of premature bearing failure and machine downtime.
- Simplified Maintenance: The separable design facilitates easier inspection, lubrication, and replacement, lowering maintenance costs.
- Improved Operational Efficiency: Low friction characteristics contribute to reduced energy consumption and cooler running temperatures.
- Design Flexibility: Accommodates thermal expansion and contraction of the shaft, preventing excessive axial stresses on the bearing.
- Extended Component Life: By effectively managing radial loads and allowing axial float, it reduces stress on the shaft and housing, extending the life of the entire assembly.
