A radial lip seal such as the DBH 1281Pol keeps lubricant inside a housing and keeps dust, wash water and particles out along the rotating shaft. Because the lip rides on the shaft, it wears over time, so a trail of oil or grease around the housing usually means it is time to pull the old one and fit a replacement. MR supplies this seal and helps you match it to the bore and shaft you are working with.

Reading the code tells you what you have. The 1281Pol carries an A 308 profile, and the three figures that matter are shaft 58 mm, housing 103 mm and height 12.00/20.00 mm. That split height points to a body that seats in the housing plus a flexible lip section, a shape used when the seal sits down inside a recessed bore. One face grips the shaft, the other holds the part in the housing. Check these values against the manufacturer's data sheet before you order.

You will find seals of this type in gear reducer boxes, pumps, electric motors, rollers and transmission equipment, where a shaft turns inside a lubricated housing. They also show up on conveyors, agricultural machinery and process lines. Two jobs happen at once: oil or grease stays where it belongs, and whatever is floating around outside, dust, washdown water, grit, stays out. In dirty plants or areas that get hosed down regularly, that barrier is what keeps the bearing alive.

Installation is mostly about cleanliness and alignment. Wipe the housing and shaft, look for burrs, nicks or a wear groove that could cut the lip, and coat the lip with the same oil or grease the equipment runs. Press the seal in square, using a tube or driver that pushes on the outer case rather than the lip. If the shaft is already worn, a repair sleeve or a seal with an offset lip is a common way out. Speed, temperature and lubricant type drive the final choice.

Looking for an equivalent? Send the 1281Pol code with your shaft, housing and height measurements, and a photo of the failed seal if you have one. With that we can check alternatives in the same brand or in another line MR carries, and we can advise when the bore has a different recess or the shaft shows wear. The more detail you send, the quicker we land on the right part.
