Technical Details and Material Specifications

The Elring differential seal 755.340 is made from ACM (polyacrylate), a material known for its excellent resistance to oils, heat, and aging. This makes it suitable for the demanding environment of automotive differentials. The seal features a dust cover with an integrated dust lip, which helps prevent external contaminants from entering the differential housing. With an inside diameter of 47.0 mm and an outside diameter of 98.3 mm, the seal fits securely around the shaft and housing. The 19.8 mm height ensures the seal sits correctly to maintain a tight barrier. The radial shaft seal design (SP) supports dynamic sealing performance, accommodating shaft movement while maintaining leak prevention.
