Industrial Bearing Cylindrical Roller Bearing NJ314 NJ314EM NJ314 NJ315 NJ316
Cylindrical roller bearings without ribs on the inner or outer ring, the inner and outer rings can move axially relative to each other, so they can be used as free end bearings.
If you want to know more details, please feel free to contact us.
Cylindrical roller bearings with double rib on one side of the inner ring and outer ring and single rib on the other side of the outer ring can bear a certain degree of axial load in one direction. Usually, steel stamping cages or copper alloy solid car cages are used. But some use polyamide molded cages.
Cylindrical rollers and raceways are linear contact bearings. Bearing capacity, mainly bear radial load. The friction between the rolling element and the rib of the retaining ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs, 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 structure in which the inner ring and the outer ring can be separated.
