Cylindrical rollers have a linear contact structure with the raceway, which has excellent load-bearing capacity and mainly bears radial loads. The friction resistance between the rolling element and the sleeve edge is relatively small, making it suitable for high-speed operating conditions.
According to the differences in the configuration of the ring edge, it can be divided into NU, NJ, NUP, N, NF series single row cylindrical roller bearings, as well as NNU, NN series double row cylindrical roller bearings; The bearing adopts a separable structure of inner and outer rings.
Cylindrical roller bearings with inner or outer rings without blocking edges, capable of achieving axial relative displacement between the inner and outer rings, suitable for free end assembly of equipment; A cylindrical roller bearing with dual gear edges on one side and a single gear edge on the other side is equipped with a ring, which can bear axial loads of a certain value in one direction.
