The DBH 8274Pol is a radial shaft seal that sits between a rotating shaft and a stationary housing. Its job is to hold lubricant in place and keep dust, water and other particles out. With a 56 mm shaft, an 80 mm housing bore and a 10 mm height, it suits gearboxes, pumps and transmission equipment where space along the shaft is tight. MR supplies this brand and helps you match the seal to the application.

The part is identified by its DBH 8274Pol designation and by three measurements you will find on the product page: shaft 56 mm, housing 80 mm, height 10 mm. The Lx-R H design refers to a sealing lip and a construction configuration set by the manufacturer. In service, the lip rides against the turning shaft and forms the barrier that stops oil or grease from escaping, while the outer diameter seats in the bore and holds the seal in position.

Seals of this size turn up in gear reducers, centrifugal pumps, electric motors and power transmission assemblies in general. The common thread is a shaft rotating inside a housing where the lubricant has to stay put, outside contamination has to stay out, and bearings and gears need protection over time. Machine tools, process equipment and low-pressure hydraulic systems also use this type of component.

When installing a radial shaft seal, start by confirming the shaft is free of burrs and wear and that the bore is clean and undistorted. Lubricate the lip before pressing the seal in, and apply the installation tool to the outer diameter rather than the lip. For selection, dimensions are only part of the picture; the fluid being sealed, the working temperature and the peripheral shaft speed all matter, and those points are checked against the manufacturer's product page to confirm the Lx-R H design fits the case.

If you are after an equivalent, send the complete part number, a photo of the part and caliper readings. From there we can look for options in the same category or from other brands we carry, keeping the shaft, housing and height dimensions intact. We can also tell you whether a replacement with similar characteristics is worth evaluating.
