Cylindrical roller bearings NJ311 NJ312 series flanged sealed bearings

Cylindrical roller and raceway for line contact bearing. Large load capacity, mainly bearing radial load. The friction between rolling body and ring retaining edge is small, suitable for high speed rotation. According to whether the ring has a side, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings. The bearing is a detachable structure with inner and outer rings.
Cylindrical roller bearings with inner ring or outer ring without flank, the inner ring and outer ring can move relative to each other in axial direction, so they can be used as free end bearings. One side of the inner ring and the outer ring has a double flank, and the other side of the ring has a single flank cylindrical roller bearing, which can bear a certain degree of axial load. A steel plate press cage is usually used, or a solid cage is made of copper alloy. But some use polyamide forming cages.

3.Product Characteristics

Cylindrical roller and raceway linear contact, radial load capacity is large. It is suitable for both heavy load and impact load as well as high speed rotation.
The raceway and rolling body of cylindrical roller bearing have geometric shapes. After the improved design, the bearing capacity is higher. The new structure design of the roller end face and the roller end face not only improves the bearing axial bearing capacity, but also improves the lubriexcavatorion condition of the roller end face and the contact area of the roller end face and the roller end face, and improves the bearing's performance.
