A radial shaft seal in the DBH line, the DBH 8041 keeps lubricant where it belongs and keeps dust and grit out of rotating assemblies. Its Mx design combines a metal outer body with a flexible sealing lip, so it presses into the housing bore and rides against the shaft. The size is written as shaft 70 mm, housing 85 mm, height 8.50 mm.
Reading the number helps when you reorder. The 8041 code pins down one specific size in the DBH range, while the three figures describe the fit: 70 mm is the shaft the lip contacts, 85 mm is the bore the body presses into, and 8.50 mm is the overall height. Because the outer dimensions follow the original housing, a worn seal can be pulled and replaced without machining anything.
Gearboxes, centrifugal pumps, electric motors, line shafts, and farm or plant machinery all rely on this kind of seal. In each case the job is the same: hold oil or grease in, hold particles out, and protect the bearings and gears behind it. The 70 x 85 x 8.50 mm envelope suits medium-power units where radial room is tight and the assembly cannot grow.
Installation decides how long the seal lasts. Check the shaft for burrs, scratches or a worn groove, and make sure the sealing surface is clean and lightly oiled. The housing bore needs the correct tolerance for a press fit, and the seal should go in square, with pressure on the outer body rather than the lip. A shaft that is already grooved may call for a wear sleeve. Lip compound — nitrile, viton and similar — is chosen around the working temperature and the fluid being sealed.
If you are cross-referencing, the 8041 code or the three dimensions are enough to start. MR Industrial Accessories supplies the DBH brand and can point you to a suitable equivalent. Details such as fluid type, operating temperature and shaft speed make the recommendation more precise.

Frequently asked questions
- What size is the DBH 8041 oil seal?
- Shaft 70 mm, housing 85 mm, height 8.50 mm. Those three values must match the shaft and bore of your equipment for the seal to seat correctly.
- Where is this seal typically used?
- Rotating equipment such as gearboxes, pumps, electric motors and general drive shafts, where it retains lubricant and blocks contaminant entry. It fits assemblies with limited radial space.
- How do I ask for an equivalent or a similar seal?
- Contact MR by WhatsApp or email with the 8041 code, or with the shaft, housing and height dimensions. Adding fluid type and working temperature helps narrow down the options.
