Product Overview: The NJ 222 Cylindrical Roller Bearing
The NJ 222 bearing is a high-capacity, single-row cylindrical roller bearing with dimensions of 110x200x38mm. As part of our extensive Cylindrical Roller Bearings collection, this component is engineered to handle very high radial loads at high speeds. The NJ design features two integral flanges on the outer ring and a single integral flange on the inner ring, which allows the bearing to locate the shaft axially in one direction. This makes it an excellent choice for applications requiring both robust radial support and single-direction axial positioning.
Manufactured to precise industry standards, the NJ 222 bearing ensures reliable and efficient performance. Its separable design, where the inner ring can be mounted independently from the outer ring and roller assembly, simplifies both installation and maintenance procedures. This bearing is a critical component in heavy-duty industrial machinery, offering durability and operational stability.
