DYS, Deep groove ball bearing production line.

It is fully automatic bearing grinding processing, finished product assembly line production. Grinder production line includes: rough grinding, fine grinding, grinding and testing of bearing inner rings and outer rings;


Finished product assembly line production includes:

 Inner and outer diameter inspection、Parts cleaning、Sorting, matching、Cage installation、Cage riveting、Finished product cleaning、Steel ball and cage defect detection、Flexibility, clearance detection、Noise detection (BVT)、Spin dry, grease on both sides、Double-sided press-fit seals、Distributing the grease evenly、Automatic product appearance test、Artificial appearance review、Appearance anti-rust into the package.


The fully automatic production line improves the productivity while making the product quality more stable and high-quality, and shortening the delivery time, making it more competitive in the market.

DYS, Water pump bearing double row raceway grinding process.

Servo feeding and trimming are adopted to ensure the consistency of groove center distance, groove curvature and groove size of double row raceway, to make the service life of bearing is longer.
DYS, Bearing ring forging and turning process
How much do you know about the manufacturing process of Chinese bearings? 
The bearing ring adopts the forging process, making the product quality more stable, the wear resistance better, and prolong the service time of the bearing.

DYS, Water pump bearing double row Superfinishing process

Adopt imported oilstone and high precision ultra Superfine equipment  to Super fine the bearing raceway,control Ra not to exceed 0.05 ,to make the bearing quieter under high-speed operation.

DYS, Wheel bearings grinding process.

Servo feed and trimming are adopted to ensure that the groove center distance and curvature of the double row raceway are the same, the groove size is better consistent, and the service life of the bearing is longer.


DYS, Tensioner bearings automatic production line.

Automatic assembly line is adopted from bearing parts-fitting-cleaning-oiling-pressure sealing ring- noise measurement to make the quality more stable.


DYS BEARINGS, Program for laser printing logo.

Trademarks and numbers can be printed on the end face of the bearing as required, which can be used to help sell and identify products.


DYS, Bearing rings production processes.

The original small lathe technology is not used, adopt CNC machine to connect production,  One time positioning production raceway, sealing groove, chamfering, etc., so that the product concentricity is better.


DYS, Bearing steel ball production process.

Even one G10 / Z4 steel ball must be made of high-quality GCr15 material, which is manufactured through more than ten processes, such as billet heat treatment grinding and processing ultra precision grinding .etc
