Product Overview: The NJ 317 Cylindrical Roller Bearing
The NJ 317 is a high-capacity single-row cylindrical roller bearing designed to handle demanding industrial applications. With principal dimensions of 85x180x41mm, this bearing is a key component in our Cylindrical Roller Bearings range. The NJ designation signifies a specific design where the inner ring features two integral flanges and the outer ring has a single flange. This configuration allows the bearing to accommodate heavy radial loads and also locate the shaft axially in one direction, making it ideal for applications requiring both robust radial support and precise shaft positioning.
As part of the versatile NJ 300 Series, the NJ 317 bearing is manufactured to the highest industry standards using premium-grade bearing steel. Its separable design, where the outer ring can be dismounted from the inner ring and roller assembly, greatly simplifies both installation and maintenance procedures. This bearing is engineered for high performance, offering low friction and high-speed capabilities essential for modern machinery.
