CHG Bearing:High quality rollers-rolling element

Huigong bearing roller production line can produce all kinds of high-precision cylindrical and tapered rollers in the range of φ15mm to φ160mm in diameter and 20mm to 220mm in length, with an annual output of 10 million pieces and product precision up to G1 and G1A (Grade I) standards. More than 150 sets of various precision equipment, and various perfect special testing instruments, ultrasonic flaw detection (UT), magnetic particle flaw detection (MT), eddy current flaw detection (ET) instruments, spectrometer, carbon and sulfur analyzer, roundness meter, contour roughness meter, etc. The heat treatment line can independently guarantee product quality, fully realize quality control adopted in the whole process from raw materials to finished products, the production process of turning, heating and grinding in an orderly manner and the flaw detection, sorting, oiling and packaging completed in one stop.

2. Optimum Crowned Generatrix Roller and Logarithmic Crowned Roller

When the roller generatrix is straight, the surface of the roller generatrix undergoes elastic deformation, and there will be stress concentration at the rounded corners of the two ends (as below); the middle part of the modified roller is straight, and the two ends adopt circular transition, which relieves the stress concentration at the unbalance load; for some working conditions with high reliability requirements (wind power spindle bearings), the logarithmic curve roller profile is the best choice, it not only can avoid the stress concentration at the rounded ends, but also make the load distribution more uniform, which greatly improves the roller's reliability and lifespan.

3. Spherical Substrate Tapered roller

The radius deviation of tapered roller's spherical substrate can be controlled within 2%, and the stable spherical substrate can improve the contact form and contact position of roller and rib, and reduce the friction and noise level during operation.
