Bearing applications

Construction Machinery: Custom bearings are widely used in construction machinery equipment, including excavators, cranes, tower cranes, concrete pump trucks, rotary drilling rigs, and other critical rotating mechanisms. Custom bearings can be specifically optimized in terms of size, rolling element structure, gear ring type, and sealing method.

Industrial Robots: Robot joints typically require bearings with high precision, low friction, high rigidity, low noise, and long lifespan.

Custom bearings can be used for robot joint bearings, lightweight bearings, and precision slewing bearings.

Medical Equipment: Medical equipment requires bearings that are quiet, stable, vibration-free, highly precise, durable, have special seals, and are corrosion-resistant.

Typical applications include medical robotic arms, rotating platforms for CT, MRI, and X-ray.

Wind and Solar Tracking Systems: Wind turbines and photovoltaic tracking systems place extremely high demands on bearings: they must withstand massive loads, operate in extreme environments, and guarantee 20+ years of long-term reliability. Custom-designed large-diameter slewing bearings and tracking system bearings can feature: special sealing structures, corrosion-resistant coatings, and long lifespans, making them ideal for single-axis and dual-axis solar tracking systems, as well as wind turbine yaw and pitch systems.

Metallurgical Equipment: The metallurgical industry operates under harsh conditions, including high temperatures, heavy loads, and long continuous operating times.

Bearings are commonly used in tunnel boring machines, steel rolling mills, continuous casting machines, and heavy-duty rotating platforms. Custom-designed bearings can utilize high-temperature resistant materials, undergo enhanced heat treatment, and feature special lubrication and sealing structures to ensure stability and longevity in extreme metalworking environments.
