Raw Material

The selection of raw materials is a fundamental step in the production of high-quality bearings. The development and choice of high purity steel is crucial in order to achieve greater durability than required by the ISO standards referred to.

Granville standard bearings are manufactured with 100 Cr6 grade steel, which ensures high levels in terms of:

• Hardness
• Wear resistance
• Resistance to fatigue
• Dimensional stability
• Mechanical strength
• Compressive strength

This type of steel combined with a heat treatment, is an excellent solution for various applications.


Quality Control

Granville as a manufacturer of high quality products, guarantees compliance with the highest standards relative to the use of the best steel quality in the production process, the highest standards in the design of contact surfaces, as well as the most efficient packing and lubrication of parts. From material coming, quality control through all processes. Except for interal test, goods to third party inspection if required. After the center of inspection and experiment is founded, effective methods of inspecting all kinds of raw materials are mastered and then the reliability of bearings is ensured. One of our main objectives is the continued improvement in the quality of our products and processes, in pursuit of which we obtained ISO certification 9001:2008 and TS16949.
