Introduction to cylindrical roller bearings

The cylindrical rollers and raceways are line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the ring rib is small, making it suitable for high-speed rotation. Depending on whether the ring has ribs, it can be divided into single-row cylindrical roller bearings such as NU, NJ, NUP, N, and NF, and double-row cylindrical roller bearings such as NNU and NN. This bearing has a separable inner ring and outer ring. Cylindrical roller bearings with no ribs in the inner ring or outer ring. The inner ring and outer ring can move relative to each other in the axial direction, so they can be used as free-end bearings. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. Generally, steel plate stamping cages or copper alloy machined solid cages are used. However, some use polyamide molded cages.
