Abstract
A unitized wheel bearing seal includes inner and outer metal casings each of which has a cylindrical wall press fitted between inner and outer concentric bores in a wheel bearing to seal a lubricant space. The outer bore is stationary, and the inner metal casing has a radially extending outer annular flange. A two lip, unsprung seal extends from the inner casing, one leg engaging the annular flange and the other engaging the cylindrical wall of the outer casing, each at an acute angle, with a lubricant containing cavity formed between them. This orientation allows the lips to flex away to allow pressure egress from the lubricant space, but prevents flexing in the other direction to block the ingress of contaminants from the ambient. The spinning annular flange also acts as a slinger to prevent contaminant entry.
