Product Overview: The N 205 Cylindrical Roller Bearing
The N 205 bearing is a single-row cylindrical roller bearing engineered for applications requiring high radial load capacity and the ability to accommodate axial displacement. With principal dimensions of a 25mm bore diameter, 52mm outer diameter, and 15mm width, this bearing is a key component in our N 200 Series of Cylindrical Roller Bearings. The 'N' design features two integral ribs on the inner ring and a smooth, ribless outer ring. This configuration allows the shaft to move axially relative to the housing in both directions, making it an excellent choice as a non-locating bearing to compensate for thermal expansion or minor mounting inaccuracies.
Manufactured to precision standards, the N 205 offers robust performance and reliability in demanding industrial environments. Its separable design, where the outer ring can be mounted independently of the inner ring and roller assembly, simplifies both installation and maintenance procedures, reducing downtime. This bearing is ideal for machinery where heavy radial loads and high speeds are primary operational factors.
Key Features of the N 205 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement: The N-type design accommodates axial movement of the shaft relative to the housing in both directions, ideal for thermal expansion.
- Separable Design: The inner and outer rings can be mounted separately, which simplifies installation, inspection, and maintenance routines.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, enabling operation at high rotational speeds.
- Robust Construction: Made from high-purity, hardened bearing steel for exceptional durability and long service life.
- Dimensional Stability: Precision manufacturing ensures consistent performance and interchangeability.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts under heavy radial stress.
