When a rotating shaft needs its lubricant kept in and contaminants kept out, a radial shaft seal does the work. The DBH 8510Pol is a single-lip seal sized for a 42 mm shaft, a 62 mm housing bore and an 8 mm width, a combination that shows up often in gearboxes, pumps and mid-size electric motors. MR Industrial Accessories supplies it within its seals and oil seals range.
Reading the size is straightforward: shaft 42 mm, housing 62 mm, width 8.00 mm. The 8510Pol designation covers that size in the DBH line, and the Lx-H build means a sealing lip with a spring plus an outer metal case, press-fitted into the housing with the lip riding on the shaft. Where the bore and shaft match the original machining, it drops in as a replacement part.
Typical service is continuous rotation where oil or grease has to stay contained: gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. The same seal also turns up in dusty or wet areas, where the lip has to keep particles and moisture away from the bearing. In those conditions, check shaft hardness and surface finish before you install a new one.
Selection comes down to three checks. Confirm the shaft diameter falls inside the recommended tolerance for radial shaft seals, inspect the housing bore for burrs or scratches, and look at the shaft for a worn track left by the previous seal. Lubricate the lip before mounting. If a groove has formed on the shaft, shifting the seal slightly or fitting a wear sleeve can be an option.
Sending us the code 8510Pol together with the shaft, housing and height measurements, and a photo of the old seal when you have one, lets us search for an equivalent in the DBH line or in other brands we carry. We can also help when a housing has been modified and the original size no longer fits.
The DBH brand sits within the seals and oil seals catalog at MR Industrial Accessories. For this size or a specific application, message us on WhatsApp with the code 8510Pol and we will come back with the technical details you need to decide.

Frequently asked questions
- What size is the DBH 8510Pol oil seal?
- Shaft 42 mm, housing 62 mm, height 8.00 mm. The Lx-H design uses a sealing lip with a metal case, and these figures match the 8510Pol designation in the DBH line.
- How can I tell whether this seal replaces the one already fitted?
- Measure all three: shaft, housing and height. If you get 42, 62 and 8 mm, it is a direct replacement. Also confirm the lip type and material suit your fluid and operating temperature. A photo helps if you are unsure.
- Can I ask for another size or an equivalent?
- Yes. Send the code 8510Pol and the dimensions you need on WhatsApp, or a photo of the original seal. We look at alternatives in the DBH line and other brands we carry so you can compare before requesting a quote.
