Manufacturing processes
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 internal test, goods to third party inspection if required. After the center of inspection and experiment is founded, effective methods of inspecting all kinds of row 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.


Quality control
The comprehensive application of automation production lines is a premise to ensure product's stable quality, what's more, it is a mark that the enterprises improve to disital management modern high-tech manufacturer.

Seiko quality, the pursuit os excellence: the control and improvement of quality is the constant pursuit of Granville, in strict accordance with the system of the provisions of the qyality of each process.

We strictly follow the core of quality management process control:
APQP: product quality advance planning
SPC: Statistical process control
MSA: Measurement system analysis
FMEA: Analysis of potential failure modes and consequences
PPAP: Production part approval procedure

In the factory testing laboratories, various bearing parts are examined in detail. The factory has its own professional bearing life tester, after bearing life and durability test, our bearings have the advantages of long service life, and high durability. We are keeping introduction of the latest measurement and testing equipment. Quality procedures are based on extensive, repeatedly carried out product tests - both before inclusion in the range and after.
