Open the CIPO recordAbstract From the Canadian patent
An outer seal for a drive-axle-wheel hub keeps axle-gear lubricant separated from wheel-bearing grease by preventing leakage to and from the wheel-bearing cavity at the outer end of the spindle. A sleeve-like outer-seal journal (50) is pressed into a groove (60) in the outer face of an outer lock nut (38). A seal-carrier ring (62) fits over the wheel hub drive studs (22) between a hub (16) and an axle-shaft cap (42). The ring (52) carries a lip-type resilient outer seal (52) that slidably presses against the outer seal journal (50). Wheel bearing life is extended. -13-

Why it's free to use
- Filed June 17, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 17, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 17, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
