FAQ

Its main purpose is to scrape dirt, dust, moisture, and other contaminants from the piston rod as it retracts into a hydraulic or pneumatic cylinder. This prevents abrasive particles from damaging other seals, the rod surface, and internal components, thereby extending the service life of the system.

NBR (Nitrile Butadiene Rubber) offers excellent resistance to most mineral oil-based hydraulic fluids, fats, and greases. However, it is not recommended for use with synthetic fluids like Skydrol, brake fluids (glycol-based), or fluids with high aromatic content, as these can cause the NBR material to swell and degrade.

These dimensions define the seal's geometry: 90 mm is the inner diameter (DI), which corresponds to the piston rod diameter. 102.2 mm is the outer diameter (DE), which fits into the cylinder housing groove. The 7.1 mm and 12 mm likely refer to the seal's axial height (HL) and overall width, respectively, which are critical for ensuring a correct fit and function within the seal groove.
