Construction machinery

Construction machinery has special requirements for bearing cages, which need to have high strength, wear resistance, corrosion resistance, self-lubricating material properties, high dimensional accuracy, shape compatibility, and advanced processing technology. At the same time, they are required to be high-temperature resistant, low noise, and environmentally friendly to ensure stable operation and long service life under complex working conditions.

Applications and Products

Shield machine main shaft bearing cage

Shield machine main shaft bearing cage

The bearing cage of the shield machine main shaft is an important component of the main bearing of the shield machine. Its design features high strength, resistance to deformation, good thermal conductivity, strong wear resistance, and high precision. The main thrust roller way bearing cage adopts a ring-guided bearing cage method, with a staggered slope design for the pocket holes. The auxiliary thrust roller way bearing cage and the radial roller way bearing cage use a segmented structure, with lubrication oil grooves set on each segment of the bearing cage, which helps improve the performance and service life of the bearing cage.
Wire rolling path bearing cage

Wire rolling path bearing cage

Using high-strength steel wire to achieve lightweight, reduce weight, and improve operational efficiency. High flexibility and elasticity allow it to adapt to small deformations and vibrations, enhancing stability and lifespan. Good thermal conductivity aids in heat dissipation, preventing high-temperature performance degradation. Special surface treatment makes it resistant to high temperatures and corrosion, ensuring stable operation in harsh environments. Mature manufacturing processes ensure high precision and consistency, which are crucial for assembly quality and operational performance. Lightweight and with good elasticity, it becomes an ideal choice for high-speed motors, construction machinery, and other high-speed operating scenarios.
Heart-adjusting roller bearing cage

Heart-adjusting roller bearing cage

The spherical roller bearing cage is widely used in the field of engineering machinery, such as cranes, road rollers, and vibrating screens, due to its high load capacity, impact resistance, ability to compensate for shaft bending and misalignment, and optimized lubrication performance. It ensures the stability and reliability of the equipment while reducing energy consumption and extending the normal operating time of the equipment.
