Cylindrical roller bearings have linear contact between the cylindrical rollers and the raceway and have large radial load capacity. They are suitable for withstanding heavy loads and impact loads, as well as high-speed rotating types and models that can move axially and can adapt to thermal expansion or installation errors. Caused by changes in the relative position of the shaft and the housing, it is most suitable for use as a free-end bearing. Types and types can withstand a certain degree of one-way axial load, and types and types can withstand a certain degree of bidirectional axial load. The inner ring or outer ring can be separated. , easy to assemble and disassemble and has strong radial load resistance, mostly used in machine tool spindles.
Mainly applicable cages are steel plate stamped cages (shaped), copper alloy cut cages, pin cages, and synthetic resin molded cages.
Mainly used for medium and large electric motors, generators, internal combustion engines, gas turbines, machine tool spindles, reduction gears, loading and unloading machinery, and various industrial machinery.
Solid type needle roller bearings
The basic structure of bearings with an inner ring is the same as that of cylindrical roller bearings, but due to the use of needle rollers, the volume can be reduced and can withstand large radial loads. There is no need for an inner ring bearing. Use the mounting surface of the shaft with appropriate accuracy and hardness as the raceway surface.
Mainly applicable cages are steel plate stamped cages.
Main uses: automobile engines, transmissions, pumps, excavator track wheels, hoists, bridge cranes, and compressors.
