The DBH 9935 seal is a single-lip radial seal that mounts on the shaft and inside the housing to retain oil or grease and exclude dust and water. Its A 294 design combines a sealing lip with a dust lip, making it suitable for equipment exposed to contamination. It is used in gearboxes, pumps, electric motors and transmissions where the shaft rotates on bearings and the lubricant must be protected.

This item is a DBH 9935 radial shaft seal with the following dimensions: shaft diameter 39 mm, housing diameter 76.50 mm and total height 10.50/14.00 mm. The A 294 design corresponds to a seal with a double lip: one sealing lip toward the oil and one dust lip toward the outside. The inner lip works on the shaft and the outer one on the housing; the variable height indicates that the mounting section is 10.50 mm and the dust lip protrudes up to 14.00 mm. The elastomer is resistant to mineral and synthetic oils, and the internal spring maintains contact pressure.

Typical applications for a seal of these dimensions are gearboxes, speed reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases it performs two functions: preventing lubricant leakage to the outside and blocking the ingress of dust, water or particles that damage the bearings. It is commonly found in equipment where the shaft rotates at medium speeds and the working temperature does not exceed the limits of the elastomer.

To install it, verify that the shaft is clean, free of burrs and marks, and that the sealing surface has suitable roughness. Lubricate the lip with the same grease or oil as the equipment before sliding it on; do not hit it or install it dry. The housing must be straight and free of steps. When selecting a replacement, respect the shaft diameter, housing diameter and height; if the A 294 design is not available, a seal with an equivalent dust lip may work, but confirm it with us.
