Four cylindrical roller and the raceway for the line contact bearings

Four cylindrical roller and the raceway for the line contact bearings. Load capacity, the main radial load. taper roller bearing The rolling element and ring wall friction is small, suitable for high-speed rotation. According ring without ribs, can be divided NU, grinding spindle 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. Inner or outer wall of the cylindrical roller bearings, the inner and outer rings relative to the axial movement can therefore be used as free-end bearings.  Four-Row Taper Roller Bearing  On either side of the inner and outer 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 direction. General use of steel stamping cage, or copper alloy machined cage. But there are also some use of polyamide forming cage.
