Part number 9453 is a DBH radial shaft seal that keeps lubricant where it belongs and keeps dust, water and particles out of the assembly. It sits in a fixed housing and its lip runs against the rotating shaft. The designation 44 x 72 x 10 mm covers shaft, housing and height, and the Lx design points to a single lip with spring for lubricated rotating shafts.

Reading the code is straightforward: shaft 44 mm, housing 72 mm, height 10 mm, with the metal outer case pressed into the bore by interference and the elastomeric lip riding on the shaft. The Lx configuration is a single lip with spring, so it needs lubrication at the contact point. Treat it as a wear part, because the lip eventually hardens or loses material and sealing drops off.

Seals in this size range turn up in gearboxes and reducers, centrifugal pumps, electric motors, compressors, and belt or chain drives. Agricultural machinery, material handling equipment and process lines with a shaft spinning inside a stationary housing are common hosts as well. Two jobs are always in play: holding oil or grease in and keeping contamination out.

Before pressing a new seal in, confirm the shaft is clean and free of burrs, nicks or a polished track, and that surface roughness matches what the seal needs. Coat the lip with lubricant, then drive the seal with a tube or spacer that contacts the outer face, never the lip. Where the bore has a chamfer, follow its angle so the case is not distorted on the way in.

Choosing a replacement means looking past the three dimensions. Fluid type, operating temperature and shaft speed all affect whether a given seal will hold up. Send part number 9453, the 44 x 72 x 10 mm figures, a photo of the old seal, or the equipment data, and the team checks the manufacturer's data sheet to confirm fit and suggest a match from the DBH line or another brand in the catalog.
