It can simultaneously withstand comprehensive loads such as axial, radial loads, and overturning moments, with a relatively high load - bearing capacity.
The structural design is relatively compact. It is equipped with mounting holes, lubricating oil holes, and sealing devices, etc., which can meet the different needs of various main engines under different working conditions. Moreover, it is easy to install and convenient to integrate into various mechanical devices.
It uses large - diameter balls or rollers, which can maintain high stiffness even under heavy loads, reducing errors caused by deformation and improving rotational accuracy. At the same time, it has a larger contact area, enabling it to bear greater radial and axial loads.
It is made of high - quality materials and advanced heat - treatment technologies, with good wear resistance and corrosion resistance, ensuring a long service life and stability. In addition, the sealing design effectively prevents the intrusion of dust and impurities, further improving reliability.
It is easy to install. You only need to make a simple selection and installation according to the specifications and dimensions of the bearing. Maintenance is also relatively easy. Good performance can be maintained through simple operations such as lubrication or grease replacement.
Such as earth - moving machinery, excavators, road rollers, tunnel boring machines, etc.; in concrete machinery, including concrete pump trucks, concrete mixing and distributing boom integrated machines, sand mixers; in hoisting machinery, such as wheeled cranes, crawler cranes, portal cranes, tower cranes, fork cranes, mobile cranes, gantry cranes, marine cranes; in foundation treatment machinery, including impact reverse - circulation drills, rotary drills, impact - rotary drills, rotary bored piles, reverse - circulation rotary drills, positive - circulation rotary drills, long - screw engineering drills, submersible engineering drills, static pile drivers, pile hammers; in engineering ships, such as dredgers; in special vehicles, including bridge inspection vehicles, fire trucks, window cleaners, self - propelled aerial work platforms, etc.
It is applied in trailer fields such as agricultural trailers, irrigation systems, and airport luggage racks. In vehicles, it can transmit axial loads, radial loads, and torques. In other applications, it mostly transmits axial loads.
In wind power generation, it is used for yaw bearings (installed at the connection between the tower and the nacelle) and pitch bearings (installed at the root of each blade and connected to the hub); in the solar energy field, it is used for rotating solar power...
