Waterproof elastic joint for bearings - comprises annular fixing projections and restraining elements which fit into hollows in two bearing rings, joint being single block

摘要

The waterproof joint has two bearing rings and annular fixing projections (4) which are stopped by complementary forms in hollows (5) in one of the bearing rings (1). Annular restraining projections (7) penetrate a complementary form in the hollows (8) on the other bearing ring (2), forming a watertight space (9). Annular watertight lips (13) slide on the surface of the shoulder (15) of the second bearing ring. Annular lips (6, 12) are also disposed on each side in the fixing (4) and restraining projections, and are inclined in an axial/radial direction. The joint is manufactured as a single block of elastic material. USE/ADVANTAGE - Roller bearing abutment which is cheap and simple to produce.
