Part number 5660 from DBH is a radial shaft seal built to hold lubricant in and keep dust and water out where a rotating shaft passes through a housing. It measures 75 mm at the shaft, 90 mm at the housing bore and 13.00 mm in height, and it comes in the Mz design. Maintenance and purchasing teams use it as a replacement on gearboxes, pumps, motors and similar rotating equipment. MR Industrial Accessories supplies this brand and can help you confirm the correct seal for the job.

Reading the designation is the fastest way to check a seal against your equipment. The first figure, 75 mm, is the shaft diameter the lip runs on. The second, 90 mm, is the housing bore that holds the outer case. The third, 13.00 mm, is the overall height, or width, of the seal. The Mz design uses a sealing lip with a metal case, which is what allows it to retain grease or oil and block contaminants at the same time.

These proportions turn up regularly on gearboxes, reducers, centrifugal pumps, electric motors, machinery rollers, transmission units and industrial fan shafts. In every one of those spots the seal does the same job: it keeps the lubricant where it belongs and keeps the bearings protected from what is outside. When a seal of this size fails, the result is usually oil loss and premature wear on the internal components.

Installation decides how long the seal lasts. Inspect the shaft for burrs, scratches or a worn track before you start, and make sure the housing bore is clean and not deformed. Apply the same oil or grease the equipment uses to the lip, then seat the seal squarely. When you select a replacement, take shaft speed, operating temperature and the fluid being retained into account. A shaft with a worn track may call for a different size or a repair sleeve.

If you are looking for an equivalent, send part number 5660 or the dimensions 75 x 90 x 13 mm and note the Mz design along with your operating conditions.
