Cylindrical roller bearings

Rolling body is a radial cylindrical roller bearings, cylindrical roller in line contact with the roller bearings. Load capacity, mainly bear radial load. Rolling ring wall with small friction, suitable for high-speed rotation. Whether under the ring wall, divided NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. The bearing is the inner, outer separable structure. No inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as the free end of the bearing. In the inner and outer rings on one side of a double wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, or copper alloy machined cage. But there are also part of the use of polyamide forming cage. Main use: medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen, and lifting and transport machinery.
