The DBH 5918Pol is a radial shaft seal that sits between a rotating shaft and a stationary housing. Its job is to hold lubricant in and keep dust, water and other particles out. The dimensions are 135 mm at the shaft, 160 mm at the housing bore and 13.00 mm in height, with the Lx design. This is a large seal, so it fits equipment built around a large-diameter shaft.

The designation to look for is 5918Pol, from the DBH line. Reading the size is straightforward: shaft 135 mm, housing 160 mm, width 13.00 mm. The Lx design is a single-lip seal with a metal case and a sealing lip, intended for rotating shafts that run with lubrication. The lip rides on the shaft while the case presses into the housing, and that combination is what keeps oil or grease where it belongs and contamination outside.

Sizes like this show up in gearboxes and speed reducers, centrifugal pumps, mixers, rotary dryers and other continuous process equipment. Plants in food processing, chemical production and aggregate handling also run shafts of this diameter, and the seal plays the same role there: protecting the bearings and containing the lubricant.

Before installing a replacement, confirm the shaft is within tolerance and free of burrs, nicks or pull marks, and check that the housing bore and depth match the seal. Lubricate the lip before you press it in, keep the seal square, and avoid impact during assembly. When choosing a replacement, think about the fluid being sealed, the operating temperature and the shaft speed, and keep the Lx configuration in mind. If the old seal has a different setup, tell us and we will look for a compatible option.
