cylindrical bearing rollers

1.heavy radial loads and high speeds
2.high precision
3.Excellent Quality competitive price

Cylindrical rollers have linear contact with the raceway, and the bearings can carry heavier load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed. bearing cylindrical roller, conveyor roller bearing, radial roller bearing, miniature roller bearing, cylindrical roller bearing, NU bearing, NJ bearing, NUP bearing, N bearing, NNU bearing, NN bearing, NCF bearing, NNF bearing, single row cylindrical roller bearing, double row cylindrical roller bearing, multi-row cylindrical roller bearingFOFbearing produces cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearingsThe FOFbearing range of cylindrical roller bearings comprises the basic types1.single row cylindrical roller bearings, caged,mainly of NU, NJ, NUP and N designs2.double row cylindrical roller bearings, caged, mainly of the NNU and NN designs3.multi-row cylindrical roller bearings, caged Cages: glass fibre reinforced polyamide 6,6 cage,pressed steel cage , machined brass cage ,steel pin-type cages

The application of cylindrical roller bearing is Medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen, and lifting transportation machinery.
