Cylindrical roller bearing is a radial rolling bearing with cylindrical rollers as the rolling element. Its internal structure adopts rollers arranged in parallel, with spacers or isolation blocks installed between the rollers to prevent tilting or mutual friction, effectively preventing an increase in rotational torque. The rollers of cylindrical roller bearings are in linear contact with the raceway, with high load capacity, mainly bearing radial loads, and suitable for high-speed rotation.
Cylindrical roller bearings have the following characteristics:
Large radial bearing capacity: suitable for withstanding heavy loads and impact loads.
Low friction coefficient: suitable for high-speed rotation, with a maximum speed close to deep groove ball bearings.
The inner or outer ring can be separated: easy to install and remove.

The application fields of cylindrical roller bearings are very wide, including but not limited to:
Large and medium-sized electric motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transportation machinery.
Disassemble OF cylindrical Roller Bearing
The disassembly of bearings is a regular maintenance and is carried out during bearing replacement. After disassembly, if it is necessary to continue using or to check the condition of the bearings, the disassembly should be carried out with the same care as during installation. Be careful not to damage the various parts of the bearing, especially the disassembly of interference fit bearings, which is difficult to operate.
It is also very important to design and manufacture disassembly tools as needed. When disassembling, study the disassembly method, sequence, and investigate the fitting conditions of the bearings according to the drawings to ensure that the disassembly operation is foolproof.
The disassembly of the outer ring with interference fit requires setting several outer ring compression screws on the circumference of the shell in advance, tightening the screws evenly while disassembling. These screw holes are usually covered with blind plugs, tapered roller bearings, and other separable bearings. Several cuts are made on the shoulder of the housing cover, and they can be disassembled using pads, a press, or gently tapped.
The disassembly of the inner ring can be easily done by pulling it out with a press. At this point, it is important to ensure that the inner ring bears its pulling force. Furthermore, the illustrated pull-out card holder is often used, and regardless of the type of card holder, it must be firmly attached to the inner ring side. For this, it is necessary to consider the size of the shaft shoulder or study the machining of grooves at the shoulder for the use of drawing fixtures.
The inner ring of large bearings is disassembled using hydraulic pressure method. By setting oil pressure in the oil hole of the bearing, it is easy to pull out. Bearings with a large width can be disassembled using both hydraulic pressure and drawing tools.
The inner ring of cylindrical roller bearings can be disassembled using induction heating method. The method of heating the local area in a short period of time to expand the inner ring and then pulling it out. In situations where a large number of such bearing inner rings need to be installed, induction heating method is also used.
