Product Overview: The N 212 Cylindrical Roller Bearing
The N 212 is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. With dimensions of 60x110x22mm, this bearing is a key component in our N 200 Series, which is part of the broader N Series of Cylindrical Roller Bearings. The 'N' designation signifies a specific 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, especially where thermal expansion of the shaft occurs.
Engineered for high radial loads and high-speed operation, the N 212's line contact between rollers and raceways minimizes stress concentrations. Its separable design—where the outer ring can be mounted independently of the inner ring and roller assembly—greatly simplifies installation and maintenance procedures. Trust our expertise as a leading supplier of industrial mechanical parts to provide reliable components like the N 212 for your machinery.
Features of the N 212 Bearing
- High Radial Load Capacity: The line contact geometry between the cylindrical rollers and raceways allows it to support heavy radial loads.
- Axial Displacement Accommodation: The flangeless outer ring allows for free axial movement, compensating for shaft expansion or contraction.
- Separable Design: The inner and outer rings can be mounted separately, simplifying installation, inspection, and maintenance routines.
- High Stiffness: Provides a high degree of radial stiffness, ensuring shaft stability under load.
- Low Friction Operation: Precision engineering ensures minimal friction and heat generation, suitable for high-speed applications.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life.
