ЦИЛИНДРИЧНЫЙ РОЛИКОВЫЙ ПОДШЕХНИК

— ЦИЛИНДРИЧНЫЙ РОЛИКОВЫЙ ПОДШЕХНИК —

Cylindrical roller bearings are high-performance rolling bearings widely used in various fields such as large and medium-sized electric motors, locomotives and vehicles, machine tool spindles, internal combustion engines, generators, etc. Its unique roller and raceway line contact design enables the bearing to withstand huge radial loads, while the friction between the rolling elements and the sleeve edge is small, making it very suitable for high-speed rotation. The rollers of cylindrical roller bearings are arranged in parallel and equipped with spacers or isolation blocks between them, effectively preventing the rollers from tilting or rubbing against each other, thereby reducing the increase in rotational torque. In addition, cylindrical roller bearings can be divided into various types based on the presence or absence of retaining edges in the ring, such as single row bearings such as NU, NJ, NUP, N, NF, as well as double row bearings such as NNU and NN, to meet the needs of different application scenarios. The inner and outer rings of cylindrical roller bearings can be separated, and bearings without retaining edges on the inner or outer ring can move relative to each other in the axial direction, making them suitable for use as free end bearings. A bearing with dual ribs on one side of the inner and outer rings and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. Overall, cylindrical roller bearings have important applications in multiple industries due to their high load-bearing capacity, high stiffness, and wide applicability. Its excellent performance and reliability provide strong guarantees for the smooth operation of various mechanical equipment.
