Product Overview: The NJ 219 Cylindrical Roller Bearing
The NJ 219 is a high-performance single-row cylindrical roller bearing with dimensions of 95x170x32mm. As a key component in our Cylindrical Roller Bearings collection, this model is part of the versatile NJ 200 Series. It features two integral flanges on the inner ring and one on the outer ring, a design that enables it to locate a shaft axially in one direction. This makes the NJ 219 an excellent choice for applications requiring both high radial load support and single-direction axial positioning.
Manufactured to exacting industry standards, the NJ 219 is engineered for reliability and a long service life in demanding industrial environments. 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 widely used in heavy machinery where precision and durability are critical for operational efficiency.
Key Features of the NJ 219 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support heavy radial loads.
