Precision Grinding For Seal Rings

Seal rings are key components in hydraulic and pneumatic systems. Their flatness, parallelism, and surface finish directly affect sealing performance. Our factory has professional surface grinders and internal grinders for precision grinding for seal rings. Seal ring grinding must achieve flatness below 0.002mm and surface roughness of Ra0.2~0.4μm. This requires a flat grinding plate, the right abrasive, and an experienced operator. Our grinding technicians have over ten years of experience. They choose the best grinding plate material and abrasive grain size for different materials. These materials include carbon steel, stainless steel, copper, cast iron, and ceramics. This ensures every seal ring meets the design requirements for product.

In precision grinding for seal rings, we also control temperature and cleanliness. Grinding heat can cause deformation. Abrasive particles can become embedded in the surface and hurt sealing. We use circulating coolant to control temperature. After grinding, we clean the seal rings thoroughly with a special cleaner and dry them. Our inspection tools include flatness testers, roughness testers, and outside micrometers. These accurately check all key dimensions and tolerances. We provide product to many hydraulic cylinder and pneumatic component manufacturers. Our annual output exceeds 300,000 pieces. Seal ring quality is critical to your equipment's reliability. We hold ourselves to the highest standard for every product job.

We provide professional precision grinding for seal rings. You can send us seal ring blanks or semi-finished parts. We will grind them to your specifications. We can also handle the complete process from turning and heat treatment to grinding. The price depends on the material, accuracy, and quantity. Trust us for product that ensures your equipment stays leak-free.
