Four-row cylindrical roller and raceway for line contact bearings. Large load capacity, mainly bear radial load.
Four-row cylindrical roller bearings: rolling body and the sleeve retaining edge friction is small, suitable for high-speed rotation. According to the sleeve with or without edge, can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. The bearing is the structure of inner ring and outer ring can be separated. The inner ring or outer ring without retaining edge cylindrical roller bearing, its inner ring and outer ring can make relative movement to the axial direction, so it can be used as free end bearing. In the inner and outer ring of a side of the double retaining edge, the other side of the collar has a single retaining edge of the cylindrical roller bearings, can withstand a certain degree of a direction of axial load. Generally use steel plate stamping cage, or copper alloy turned cage. But there are also some use of polyamide forming cage.
HSN Bearing can produce its own bearings. At the same time, there are more than 20 cooperative and stable bearing suppliers and raw material suppliers. It has international advanced bearing testing equipment to ensure that the product quality exceeds It has international advanced bearing testing equipment to ensure that the product quality exceeds customer requirements, especially for Four-row Cylindrical Roller Bearings.
