Bearings face two challenges in dirty or washdown environments: keeping out contamination, and keeping lubricant safe inside. Single and multi-lip designs are often employed here, but these tend to increase drag and fail.
Another solution is E-Z KLEEN and ULTRA KLEEN bearings from Baldor Electric Corp. — Dodge, Greenville, S.C. The bearings feature mechanically retained QuadGuard seals that have two contact points on the inner ring and one that rides against a flinger surface to keep out contamination and keep in lubricants. The molded-rubber flinger provides contaminant shielding. If moisture or contamination manages to work into the bearing, an extended-diameter rubber baffle on the flinger extends to outside the bearing, and increases centrifugal acceleration during rotation to expel the ingress.
Internal grease chambers on the cage also prevent the bearing's H1 food-grade grease from escaping. Even after 24-hour salt fog tests, the largely stainless bearings (and their inserts) show no corrosion.
