Thrust roller bearings are roller bearings that mainly bear axial loads and can also bear a certain proportion of radial loads (generally not exceeding 55% of the axial load). The bearings have a low friction coefficient and high speed capability, and have self-aligning properties, which can compensate for installation errors and increase the service life and operating stability of the bearings. Thrust roller bearings have a separated structure, which is easy to install and maintain. They are widely used in large motors, lifting equipment, metallurgical machinery and other occasions that need to bear heavy axial loads. Correct tolerance control and assembly methods are essential to ensure bearing performance and life.Thrust roller bearings are rolling bearings specially designed to bear axial loads. Their core feature is that they use cylindrical, conical or drum rollers instead of balls as rolling elements, which greatly improves the axial load-bearing capacity and impact resistance. Compared with thrust ball bearings, the rollers and raceways of thrust roller bearings are in line contact or surface contact, and the contact area is significantly increased. They can withstand axial forces ranging from several tons to several thousand tons, and are suitable for heavy loads, medium and low speeds, or complex working conditions with impact and vibration.
Thrust roller bearings are mainly used to bear axial loads and can bear axial/radial combined loads within a certain range. Their radial load bearing capacity is limited, usually not exceeding 55% of the axial load. Compared with other thrust bearings, this type of bearing has a lower friction coefficient, higher speed capability, and self-aligning performance, which can compensate for installation errors or shaft deflection, and improve service life and stability.
（1）High axial load capacity
The roller and raceway are in line contact structure, with strong load capacity per unit area, suitable for heavy-load axial conditions.
（2）With self-aligning performance
It can automatically adjust the inclination angle between the shaft and the seat, reducing the dependence on installation accuracy.
（3）Low friction coefficient and high speed
Structural optimization can achieve lower starting torque and running resistance, and improve mechanical efficiency.
（4）Suitable for combined load conditions
Although the axial load is the main load, a certain proportion of radial load is allowed to adapt to more complex load conditions.
（5）Separate structure, easy assembly
Each component can be separated for easy installation, disassembly and later maintenance.
Thrust roller bearings are mainly used to bear axial loads and are widely used in heavy-load, high-speed, and high-impact working conditions. Common application scenarios are as follows:
(1) Heavy industrial and metallurgical equipment: metallurgical rolling mills, mining crushers, continuous casting machines, molten steel continuous casting equipment, etc.
(2) Energy and power equipment: such as wind turbine pitch systems, turbine propellers, steam turbines, gas turbines, etc.
(3) Heavy engineering machinery and transportation: such as shield machine cutter drives, ship propellers, marine gearboxes, railway locomotive axle boxes, etc.
(4) Mining and construction machinery: such as crane hooks, mining conveyors, excavators, bulldozers, etc.
(5) Manufacturing and stamping equipment: heavy stamping machine tools, gearbox axial positioning, extruder screw drives, etc.
