Our wheel seals are engineered using only the highest-quality materials to meet vehicle manufacturer specificatons. We work with suppliers to design seals that meet Schaeffler's quality standards. Seals are designed to protect wheel end components from contamination - such as dirt, dust, and moisture - and prevent the loss of grease over the life of the bearing. The specifications for wheel seals are very demanding, and the type required depends on the specific application, position and vehicle class.
