Special seals

SBD plummer block housings and THD take-up housings are available with taconite heavy-duty seals. Taconite heavy-duty seals are grease filled labyrinth seals that include a V-ring. They can seal against taconite, a very fine-grained mineral which is extremely difficult to seal against.
Taconite seals require a modified housing, designation suffix /VZ335. For additional information, contact the SKF application engineering service.
