Split cylindrical roller bearings

CHG® bearing has a high carrying capacity, was widely used in large and medium-sized motors, rolling stock equipment, machine tool spindle, internal combustion engine, generator, gas turbine, gear box, rolling mill machine, vibrating screen and lifting machinery etc.
Features:The single-row cylindrical roller bearing is one separable type bearing. Generally, a single-row cylindrical roller ring consists of four major components as follows: inner ring, outer ring, rollers, and cage. Series Type: NU, NJ, N, NF
Features:The double-row cylindrical roller bearing has two optional structures: cylindrical bore and tapered bore(suffix K),and two optional designs: NNU and NN. The NN design has an inner ring with two ribs and an outer ring without ribs. The NNU design has an inner ring without ribs and an outer ring with two ribs.
Features:Four row culindrical roller bearings are especially applied to rolling mills required high speed and precision, for example, wire mills, bar and shape mills, cold or hot sheet mills and cogging mills. Type: FC, FCD, FCDP
Features:The full complement cylindrical roller bearing has one or two raceways full of rollers and no cage, thus, it has a higher bearing capacity. Its main optional structures include NCF (single-row) and NNCF (double-row).
Features:Backing bearing is a special cylindrical roller bearing. Multiple backing bearings are mounted on one roll. The external surface of each backing bearing is used as part of the rolling surface. So, it is required that the backing bearings shall have uniform cross sections. The precision requirements for their parts are very strict.
