Product Overview: N 321 Cylindrical Roller Bearing
The N 321 is a high-capacity, single-row cylindrical roller bearing designed for heavy radial loads and high-speed applications. With dimensions of 105x225x49mm, this bearing is a crucial component in demanding industrial machinery. As part of our N Series, it features 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 ideal for use as a non-locating bearing.
Manufactured from high-quality bearing steel, the N 321 ensures durability and a long service life. Its separable design—where the inner ring can be mounted independently of the outer ring and roller assembly—simplifies installation and maintenance procedures.

Key Features of the N 321 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement: Accommodates thermal expansion or contraction of the shaft by allowing axial movement in both directions.
- Separable Design: The inner ring can be separated from the roller and cage assembly, facilitating easier mounting and dismounting.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from premium-grade steel for superior strength, wear resistance, and operational reliability.
- Interchangeability: Produced to strict industry standards, ensuring dimensional and running accuracy for easy replacement.
