Abstract

Disclosed is a magnetic bearing seal for use in a variety of devices which are in contact with magnetic particulate materials, for example, magnetic toners and carriers used in electrophotography. Magnetic toners and carriers tend to be very abrasive on bearings of, for example, mixers, blenders or developer housings, which shortens the operational life expectancies of the bearings.

MAGNETIC BEARING SEAL Proposed Classification David R. Santo U.S. C1.384/000

Disclosed is a magnetic bearing seal for use in a variety of devices which are in contact with magnetic particulate materials, for example, magnetic toners and carriers used in electrophotography. Magnetic toners and carriers tend to be very abrasive on bearings of, for example, mixers, blenders or developer housings, which shortens the operational life expectancies of the bearings.

Using a ring magnet in conjunction with, or integral with, the bearing rubber seals, the magnetic ring attracts and holds the magnetic toner or carrier which penetrates the bearing rubber seal and thereby prevents contact with and prevents wear of the bearing.
