Abstract
A conveyor shaft seal for isolating a shaft bearing includes a resilient surrounding frame supporting a shaft embracing anti-friction sleeve. The innermost end of the sleeve within the conveyor is angled downwardly toward the conveyor wall whereby, during operation, the ingress of the material of the conveyor at the interface between shaft and sleeve is minimized, to extend the life of the bearing.
