All seal heads are made from 6061-T6 aluminum to save weight
Air bleed hole helps remove air from the oil reservoir during seal head installation
Oil seal utilizes a double lip design and a low friction elastomer. This gives the seal head additional dirt exclusion and yet maintains a low drag (low friction) seal
The dust seal utilizes a spring type exclusion seal to maintain constant pressure and assure good dirt and contaminant exclusion over the life of the seal head
