A lip seal in the DBH line, the 9539 keeps lubricant inside the housing and keeps dust, water and particles out along a rotating shaft. Its measurements are shaft 50.57 mm, housing bore 73.66 mm and height 7.36 mm, and it comes in the A 101 design. Gearboxes, pumps, motors and power transmission assemblies are the usual places you will find it. MR Industrial Accessories supplies this brand and helps you match the seal to the job.

Reading the code is straightforward. The designation 9539 identifies the size, and the A 101 design tells you it is a single lip with a spring, which is what you want on a lubricated rotating shaft. Shaft 50.57 mm, housing 73.66 mm, width 7.36 mm. When a seal in service starts weeping or has hardened, these are the three figures you check against the bore and the shaft before anything else.

The job it does is simple but important. It holds oil or grease where it belongs and blocks the grit that would otherwise reach bearings and gears. That covers gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In plants where vibration and moderate temperatures are normal, keeping the seal in good condition is one of the cheaper ways to protect the parts behind it.

Installation decides how long a seal lasts. Clean the shaft and the bore and remove burrs or nicks first. Put a film of the same oil or grease the unit runs on over the lip. Press on the outer ring only, never on the lip itself. A scored or worn shaft is worth a look before you fit a new seal, and in that case an auxiliary lip is one option to weigh. Speed, temperature and the lubricant in use all feed into the final choice.

If you are chasing an equivalent, send the code or the dimensions on WhatsApp. We can search other brands and series as long as shaft, housing and height still line up, and we can point you toward the lip design that suits your fluid and operating conditions. MR Industrial Accessories handles seals and radial shaft seals.
