Single-row cylindrical roller bearings are separable bearings,the rollers are guided by the two ribs of bearing rings.The cage,rollers and guide ring are assembled to a unit, and can be separated from the other ring. These bearings are easy to be mounted and dismounted,especially inner and outer rings interference fit with shafts and housings.
The structures of cylindrical roller bearings are distinguished by ribs.Type N has inner ring with two ribs and outer ring without rib;type NU has outer ring with two ribs and inner ring without rib; type NJ has inner ring with rib and outer ring with two ribs, and can carry certain axial loads in one direction;type NF has inner ring with two ribs and outer ring with rib.
The application:
high speed tubular strander
