For rotating shafts that need reliable lubricant retention and contaminant exclusion, the DBH 8478 radial shaft seal is a direct-fit option. Its 145 mm shaft, 175 mm housing and 13 mm width suit gearboxes, pumps and medium-to-large reducers. MR Industrial Accessories supplies this brand and helps you match the right seal to your equipment.

The DBH 8478 is a radial shaft seal with a Kx-Bidi configuration. That designation indicates a double-lip, reinforced geometry that holds lubricant on both sides. The elastomer lip and internal spring maintain contact with the shaft and absorb minor misalignment. Key dimensions: shaft 145 mm, housing 175 mm, width 13.00 mm.

Seals in this size range appear in gearboxes, centrifugal pumps, mixers, mills and conveyors, as well as large electric motors and older machines with worn housings. In all cases, the goal is the same: keep oil or grease in and dust out.

When selecting a replacement, confirm that shaft, housing and width match the DBH 8478. Inspect the shaft surface—grooves or deep scratches will prevent proper sealing and may require repair or a sleeve. During installation, lubricate the lip with the equipment's lubricant and press the seal in evenly, avoiding tilt. Remove any burrs from the housing beforehand.

To request a quote, provide the full part number and dimensions of the old seal. A photo of the part and housing also helps. We can then suggest alternatives within the DBH line or from other brands we supply, so you avoid a mismatched seal.
