These taconite seals consist of two rings (one stationary and one rotating), which form a very narrow labyrinth between the two rings, which prevents ingress of solid and liquid contaminants, even during high-pressure washdowns. The rotating labyrinth ring carries a V-ring seal that seals against the stationary labyrinth ring. The V-ring seal blocks contaminants from entering the bearing housing and aids the purging of contamination and old grease when the seal is relubricated.
