The basic function of the transmission system is to transfer power from the engine to the driving wheels. Transmission system including gearbox, clutch, transmission shaft, differential and other parts, is the driving device of the automobile. Bearings inside, with features such as high temperature resistance, pollution resistance, long life, etc. can meet the needs of various driving needs.

Our bearings are core spare parts designed specifically for motor maintenance, playing a critical role in optimizing the efficiency and durability of transmission systems. The primary function of a motor’s transmission system is to transfer power from the engine to driving components, and it includes key parts such as gearboxes, clutches, drive shafts, and differentials. Our bearings are integrated into these systems to reduce friction between moving parts, minimize energy loss, and protect the entire transmission structure from wear and tear.
Unlike ordinary bearings on the market, our products are engineered to adapt to complex working environments—whether in high-temperature industrial settings or dusty mechanical scenarios. We adhere to strict quality control standards throughout the production process, from raw material selection (high-grade alloy steel) to precision machining (with a dimensional tolerance of ±0.005mm). This attention to detail ensures each bearing delivers consistent performance, making it a trusted choice for customers worldwide seeking long-lasting motor spare parts.
One of the standout advantages of our bearings is their exceptional high-temperature resistance. They can operate stably in environments ranging from -40°C to 180°C, a key feature that makes them suitable for motors working in high-heat conditions (such as industrial motors in manufacturing plants or energy-saving motors in power facilities). The high-temperature resistance is achieved through a special heat-treatment process on the bearing material, which enhances its thermal stability and prevents deformation or failure under extreme temperatures. This eliminates the risk of unexpected motor shutdowns caused by bearing overheating, reducing maintenance costs for users.
Our bearings are equipped with a advanced sealing structure that effectively blocks external contaminants such as dust, oil, and moisture. The double-lip rubber seal (compliant with IP65 protection standards) creates a tight barrier around the bearing, preventing foreign particles from entering the internal rolling elements. This pollution resistance ensures the bearing maintains smooth operation even in dusty industrial workshops or humid outdoor environments, avoiding premature wear caused by contamination. For example, in fan motors used in construction sites, our bearings can resist dust accumulation for up to 5,000 hours without performance degradation.
Thanks to high-quality materials and precision manufacturing, our bearings boast an extended service life of over 10,000 operating hours under normal working conditions—30% longer than the industry average. The use of high-carbon chromium bearing steel (SUJ2) enhances the bearing’s hardness (HRC 60-62) and wear resistance, while the optimized rolling element design reduces contact stress between parts. Additionally, we apply a special lubricating grease with excellent anti-oxidation properties, which further slows down internal wear and extends the bearing’s service life. This long lifespan means fewer replacements for customers, lowering overall operational costs.
Precision is critical for bearings, as even minor dimensional deviations can affect motor operation. Our bearings undergo strict precision testing, with a radial runout tolerance of 0.002mm and axial runout tolerance of 0.001mm—meeting or exceeding ISO 492 Class 5 precision standards. This high precision ensures the bearing fits perfectly with motor components, reducing noise (below 55 dB during operation) and vibration, and improving the overall stability of the motor. For high-precision equipment such as servo motors and encoders, this precision performance is essential to maintain accurate power transmission and avoid signal interference.
Our bearings are versatile and suitable for a wide range of motor types, addressing the diverse needs of different industries. Below are key application areas where our bearings deliver optimal performance:
Energy-saving motors require bearings with low friction to minimize energy consumption. Our bearings feature a optimized contact angle design that reduces friction coefficient to 0.0015, helping energy-saving motors improve energy efficiency by up to 10%. They are widely used in energy-saving motors for household appliances (such as air conditioners and refrigerators) and industrial equipment, aligning with global energy-saving trends and helping customers reduce carbon emissions.
High-voltage explosion-proof motors are commonly used in hazardous environments (such as oil refineries, chemical plants, and coal mines), so their bearings must meet strict explosion-proof and safety standards. Our bearings for high-voltage explosion-proof motors are made of anti-spark materials and undergo explosion-proof testing in accordance with IEC 60079-0 standards. They can withstand high voltage (up to 10kV) and prevent sparks from generating during operation, ensuring safe use in explosive atmospheres.
Servo motors and encoders demand ultra-precise bearings to ensure accurate position control and signal transmission. Our high-precision bearings (ISO Class 5) provide stable rotation with minimal backlash, supporting servo motors in applications such as CNC machine tools, robotic arms, and automated production lines. The low-noise and low-vibration performance of our bearings also prevents signal interference in encoders, ensuring the motor maintains high positioning accuracy (up to ±0.001mm).
Variable-frequency motors operate at varying speeds, which places fluctuating loads on bearings. Our bearings are designed with strong load-bearing capacity—radial dynamic load rating up to 55kN and axial dynamic load rating up to 28kN—enabling them to adapt to speed changes (500-3,000 RPM) without performance loss. They are also widely used in heavy-duty industrial motors for machinery such as conveyors, pumps, and compressors, providing reliable support for continuous industrial production.
Our bearings are suitable for multiple industries, including manufacturing (for industrial motors and CNC equipment), energy (for energy-saving motors in power plants), petrochemicals (for high-voltage explosion-proof motors), automotive (for transmission system motors), and robotics (for servo motors in robotic arms). Their high-temperature resistance, pollution resistance, and precision performance make them adaptable to both indoor and outdoor, light-duty and heavy-duty working scenarios.
Under normal working conditions (proper installation, regular lubrication, and operating within temperature/pressure limits), our bearings have a service life of over 10,000 operating hours. Factors that may affect service life include improper installation (e.g., excessive axial pressure during mounting), lack of lubrication (or use of incompatible lubricants), and exposure to extreme temperatures beyond the bearing’s range (-40°C to 180°C). We provide detailed installation and maintenance guides to help customers maximize the bearing’s lifespan.
Yes, all our bearings comply with international quality standards, including ISO 9001:2015 (quality management system) and ISO 492 (bearing dimensional and tolerance standards). We also hold certifications for specific applications, such as IEC 60079-0 for explosion-proof bearings and RoHS for environmentally friendly materials. These certifications ensure our products meet the quality requirements of global markets, including Europe, North America, and Southeast Asia.
