FORMING ROLL BEARING SEAL

摘要

FIELD: process engineering.SUBSTANCE: forming roll bearing seal comprises bearing assembly fitted on shaft journal and adapter with circular groove at its end, bearing cover with sealing gland seat. Said sealing gland comprises case, radial sponge with working edge interacting with adapter radial surface. Reliable contact with adapter surface in changing the position of roll rubbing surfaces relative to gland sponges is ensured by furnishing the gland with second radial sponge connected with case end face and interacting by its working edge with adapter groove inner radial surface. Said adapter has ledge interacting with extra sponge.EFFECT: higher reliability of seal.1 dwg
