Rotary seals 4x11x6 WA

Seal - shaft seal, which serves to seal the rotating shaft and the surrounding space from gaseous or liquid media. The seal is composed of an elastomer part (NBR, FPM, SI,…) metal reinforcement, a tension spring, which ensures the correct radial pressure of the sealing lip. The size of the seal is given in three parameters, the inner diameter of the shaft, the outer diameter of the seal and the height of the seal. WA version - elastic outer shell eliminates thermal expansion and surface roughness in the stored space. Type WA is applied for common sealing of liquid and gaseous media. Material version (WA) of the sealing lip: NBR (nitrile butadiene rubber).
