Product Description


——Professional Thin-Walled Bearing Manufacturing——




Constant cross-section thin-wall bearing

Thin-walled constant cross-section bearings can be deep groove ball bearings, 

four-point contact bearings, or angular contact ball bearings. 

The cross-section of thin-walled constant cross-section 

bearings is mostly square.






        High-quality management system



The power of brand        Good quality     Good guarantee


HIGH PRECISION BEARING

 Wide range of models        Bulk stocking

Precision grade bearings have high product size and rotational accuracy, high speed, low vibration, and high reliability. Through excellent precision machining technology, bearings are committed to developing precision bearing products with various precision performance requirements for customers.

                 High speed rotation                                   Low noise                             High precision                           Long lifespan


The high-precision and low friction characteristics of rolling bearings can achieve high speeds while reducing noise, heat, energy consumption, and wear, thereby reducing the risk of equipment failure.

The steel used for the ring and washer is GCr15 (AISI 52100) high carbon bearing steel, which has good comprehensive performance, high hardness, good wear resistance, and high contact fatigue strength.

The components made of high-quality materials, precision heat treatment technology, and high-precision processed steel balls and raceways ensure the long service life of the product, thereby reducing risks and improving efficiency.


Functional Features



High carbon chromium bearing steel

 Hardness can reach HRC58-61 

GCR15(AISI 52100）

HIGH QUALITY STEEL


After being certified and tested by multiple testing institutions, safety and quality are more reassuring.




International Dimensional Standards

 Advanced testing instruments 

NANOMETER measuring instrument


Rolling bearings have high precision and low friction characteristics, which can achieve high speeds while reducing noise, heat, energy consumption, and wear. The product meets universal size standards and is interchangeable with machine components.




Bainitic quenching

 Heating austenitization of bearing steel 

Bainite quenching process


After bainitic isothermal quenching, the rolling bearing rings and rolling elements obtain high hardness and strength to withstand external loads, thereby improving the bearing's wear resistance and long life characteristics.
