Product Overview: The N 203 Cylindrical Roller Bearing
The N 203 bearing is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. As a key component in our Cylindrical Roller Bearings collection, this bearing belongs to the esteemed N 200 Series. Its standard dimensions are a 17mm bore diameter, 40mm outer diameter, and 12mm width. The 'N' design features two integral flanges on the inner ring and a flangeless outer ring, a configuration that allows for axial displacement of the shaft relative to the housing in both directions. This makes it exceptionally suitable for use as a non-locating bearing.
Manufactured from high-quality bearing steel, the N 203 is engineered to handle heavy radial loads at high speeds. Its separable design, where the outer ring can be mounted independently from the inner ring and roller assembly, simplifies both installation and maintenance procedures. This bearing is a reliable choice for machinery where precision, durability, and high performance are essential.
Key Features of the N 203 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides a high capacity for radial loads.
- Axial Displacement Accommodation: The N-type design allows for thermal expansion and contraction of the shaft by accommodating axial movement in both directions.
- Separable Design: The inner and outer rings can be mounted separately, which greatly simplifies the installation, inspection, and maintenance processes.
- Low Friction Operation: Advanced roller geometry and surface finish minimize friction, reducing heat generation and enabling high-speed operation.
- Robust Construction: Made from premium-grade, hardened bearing steel for exceptional durability and a long service life under heavy loads.
- Dimensional Stability: Precision manufacturing ensures tight tolerances for consistent and reliable performance in various applications.
