Do you know 4 row cylindrical roller bearings?

4 row cylindrical roller bearings has low friction between the rolling element and the retaining edge of the ring, making it suitable for high-speed rotation. According to the presence or absence of ribs on the ring, it can be divided into single row bearings such as NU, NJ, NUP, N, NF, and double row bearings such as NNU and NN.
The 4 row cylindrical roller bearings is a separable structure with inner and outer rings. Cylindrical roller bearings without retaining edges on the inner or outer rings can move relative to the axial direction, so they can be used as free end bearings.

4 row cylindrical roller bearings with double ribs on one side of the inner and outer rings, and a single rib on the other side of the ring, which can withstand a certain degree of axial load in one direction. Generally, steel plate stamped cages or copper alloy car made cages are used. But some also use polyamide shaped cages.
4 row cylindrical roller bearings mainly bear radial and axial combined loads. The bearing capacity depends on the raceway angle of the outer ring, and the larger the angle, the greater the bearing capacity.

This type 4 row cylindrical roller bearings to the separated type and is divided into single row, double row, and four row tapered roller bearings based on the number of rows of rolling elements in the bearing. The clearance of single row tapered roller bearings needs to be adjusted by the user during installation; The clearance of double row and four row tapered roller bearings has been given according to user requirements when the product leaves the factory and does not require user adjustment.
