Precision Cylindrical Roller Bearings

Single row cylindrical roller bearing

Single-column cylindrical roller bearing is a common rolling bearing, widely used in the fields such as industrial machinery and automobiles. Its main structure includes the inner ring, the outer ring, the cylindrical roller and the holder. The roller is in contact with the roller path, which can withstand a large radial load with high rigidity and precision. Due to the large contact area, low friction and high transmission efficiency, suitable for high speed operation and heavy load conditions. Single column cylindrical roller bearings do not withstand significant axial loads and are usually used with other types of bearings in design. Regular lubrication and maintenance can extend their service life and ensure the stable operation of the equipment.

double row cylindrical roller bearing

Double row cylindrical roller bearing has two structures: cylindrical inner bore and conical inner bore. The cylindrical roller bearing bearing has the advantages of compact structure, large rigidity, large bearing capacity and small deformation after load. The conical inner hole can also play a role of micro adjustment of the gap, and can simplify the structure of the positioning device, convenient installation and disassembly.
