The DBH 9935 is a radial shaft seal built with an A 294 profile, meaning it has both a sealing lip and a dust lip. It keeps oil or grease inside the housing while blocking dust and water from reaching the bearings. This seal is a common choice for gearboxes, pumps, motors and transmission shafts where the lubricant must stay clean and contained.

The seal fits a shaft of 39 mm, a housing bore of 76.50 mm, and its overall height is 10.50/14.00 mm. The two figures in the height reflect the A 294 construction: the mounting section measures 10.50 mm, while the dust lip extends to 14.00 mm. The main lip runs against the shaft and the secondary lip faces outward. A spring inside the elastomer maintains steady contact pressure, and the material resists mineral and synthetic oils.

Typical installations include gear reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In each case the seal does two jobs at once: it stops lubricant from escaping and keeps dust, water and particles out of the bearing area. It is often specified where shaft speeds are moderate and operating temperatures stay within the elastomer's range.

Before mounting, check that the shaft is clean and free of burrs or scratches, and that the sealing surface has the correct roughness. Apply the same oil or grease used in the equipment to the lip, then slide the seal into place without striking it or running it dry. The housing bore should be straight and without steps. When choosing a replacement, match the shaft diameter, housing diameter and height; a seal with a comparable dust lip may also work, but confirm it with our team first.

If you need an equivalent, send us the code 9935 or the dimensions of the old seal. We can also search by shaft and housing sizes if the part number is missing. MR Industrial Accessories LLC supplies the DBH brand and can guide you to a suitable option for your equipment.
