NU Cylindrical roller bearings
Collect
The rolling element is a centripetal rolling bearing with cylindrical rollers. The internal structure of the cylindrical roller bearing adopts the rollers arranged in a 90° vertical and crossed arrangement with each other. Spacers or spacers are installed between the rollers to prevent the rollers from tilting or rolling. The mutual rubbing between the two can effectively prevent the increase of the rotating torque. The cylindrical roller and raceway are linear contact bearings, which have large load capacity and mainly bear radial load. The friction between the rolling element and the ring rib is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU, NN. The bearing has a separable inner ring and outer ring. structure. Cylindrical roller bearings with no ribs on the inner ring or outer ring, the inner ring and outer ring can move relative to the axial direction, so it can be used as a free end bearing. 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 bear a certain degree of axial load in one direction. Generally, steel stamping cages or copper alloy car-made solid cages are used, but some polyamide shaped cages are also used. Cylindrical roller bearings with no ribs on the inner or outer ring, the inner ring and outer ring can move relative to the axial direction, so it can be used as a free end bearing, with double ribs on one side of the inner ring and the outer ring , The ring on the other side has a cylindrical roller bearing with a single rib, which can bear a certain degree of axial load in one direction. Generally, stamping steel cages or solid cages made of copper alloy are used, but some of them use polyamide. Shaped cage. Cylindrical roller bearings are widely used in large and medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens and lifting and transporting machinery, etc. According to the accuracy grades can be divided into PO, P6, P5 , P4, P2, the accuracy level is sorted from low to high.
