The DBH 9144 is a radial shaft seal, a lip-type component that keeps oil or grease where it belongs and blocks dust and water from getting in. Its working envelope is a 36 mm shaft, a 56 mm housing bore and an 8 mm height, in the Lx design. You will find it in gearboxes, pumps, motors and transmission assemblies, and it ships from MR as part of the seals and oil seals range.
Reading the code: DBH 9144 is the item reference, and 9144 is the designation to quote. The three figures that matter are shaft 36.00 mm, housing 56.00 mm and height 8.00 mm, matched to the Lx design. In practice that means a single lip, a metal outer case and an elastomer sealing element, made to sit in a machined bore with the shaft turning inside it. Confirm bore diameter and depth, and inspect the shaft for burrs or scoring, before anything goes in.
Where it goes: gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and other power transmission equipment. The job is the same everywhere, holding lubricant in the assembly and keeping outside contamination out. Machine tools, food processing equipment and process lines also use this type of seal, since a failed shaft seal means product loss and unplanned downtime.
Choosing and fitting one: look at shaft surface finish, rotation speed, operating temperature and the lubricant in use. The lip has to run on a clean, uncorroded band of shaft. Put a film of lubricant on the lip first, then press the seal in with a tube that bears on the metal case, not on the elastomer. If the bore itself is worn or damaged, repair it or move to a seal with a wear sleeve.

Frequently asked questions
- What are the dimensions of the DBH 9144 seal?
- Shaft 36.00 mm, housing 56.00 mm, height 8.00 mm, Lx design. Check these against the shaft and bore before installation.
- How do I request an equivalent?
- Send code 9144, the shaft, housing and height dimensions, and a photo of the original seal by WhatsApp. We then look for an alternative in the radial seal line.
- What should I check before installing a radial shaft seal?
- That the shaft is free of burrs, scratches and wear at the lip track, that the bore is clean and sound, and that temperature and lubricant suit the elastomer. Lubricate the lip and use an installation tube that bears on the metal case.
