Magnetic Seal

MAGNETIC SEALĀ M003

These designs are generally used as bearing seals. The design uses magnetic materials rather than springs to keep the lapped seal faces together.

Applications are limited to non-corrosive fluids because of the magnets. There are some designs that have coated magnets to offer a limited amount of corrosion resistance.

Some people are reluctant to place magnets next to a bearing. They feel that magnets are better located in the oil sump of a pump where the can collect any loose metal particles that might be found in the oil.
