Triple-Lip Sealed Bearings for Bearing Units

Ball bearing units consist of an insert bearing mounted in a housing. An insert bearing is a deep groove ball bearing with a sphered (convex) outside surface and an extended inner ring that includes a mechanism to lock the unit onto the shaft.

These reliable triple-sealed bearings are dustproof and waterproof.

They ensure a longer bearing life even when exposed to heavy airborne dust and splashes of foul water.
