Cylindrical roller bearing
It can withstand relatively large radial loads, and some structures can also bear a certain amount of axial loads. It can meet the working conditions of heavy loads and impact loads, making it suitable for equipment with high requirements for load-bearing capacity.
Some types (such as type N and type NU) allow a certain amount of axial displacement between the shaft and the bearing housing. They can adapt to the relative position changes caused by factors such as thermal expansion, thereby improving the operational stability of the equipment.
The separable structure of the inner or outer ring makes installation and disassembly more convenient, facilitating the assembly and maintenance of the equipment as well as the replacement of the bearings. This can reduce maintenance costs and downtime.
It is commonly used in high-precision and high-rigidity CNC machine tools, such as the spindle positions of lathes and grinders. Its low friction coefficient and high rigidity can effectively improve the machining accuracy and stability of the machine tools. Single-row and double-row cylindrical roller bearings are often used.
It is suitable for the rotor bearing positions of motors. While bearing radial loads, it ensures the smooth operation of the motors. Full-complement cylindrical roller bearings are often used in large motors to withstand higher loads.
In metallurgical equipment such as rolling mills, four-row or six-row cylindrical roller bearings are used for heavy-load parts such as roll supports. Their excellent load-bearing capacity and good axial displacement compensation performance can meet the working requirements.
The working environment of mining machinery is harsh. Double-row or multi-row cylindrical roller bearings, especially those with a full-complement design, are suitable for parts such as crushers and vibrating screens. They can work stably under high loads and in highly polluted environments.
Cylindrical roller bearings with flanges achieve better axial positioning through the additional flange structure. They are widely used in the axle boxes of railway vehicles to ensure the safe and stable operation
