The DBH 9688Vit radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing, while at the same time preventing the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where lubricant must be retained in a confined space. Its A 156-R-H design and its dimensions of 28 x 42 x 5 mm place it in applications with a small shaft and a thin section.

This oil seal has a 28 mm shaft diameter, a 42 mm housing diameter and a 5.00 mm height, according to its 9688Vit designation. The A 156-R-H design corresponds to a single-lip seal with a metal case and a retaining spring, designed to be press-fitted into the housing and to seal against the shaft. It is a component of the seals and radial shaft seals category that MR Accesorios Industriales sells as an official brand DBH.

Typical applications appear in gearboxes and gearmotors, centrifugal pumps, electric motors, compressors and power transmission equipment. It is also found in machine tools, washing equipment and systems where the shaft rotates on bearings and the lubricant must be contained. In all those cases the seal works against a shaft that may have wear or roughness, so it is advisable to check the surface before replacing it.

To select the correct seal, verify that the shaft diameter, the housing diameter and the height match those of the machine's housing and shaft. Rotation speed, working temperature and the type of lubricant influence the service life of the lip. When mounting it, lubricate the lip, avoid hitting it and make sure it enters perpendicular to the housing; if the shaft has burrs or a groove, correct it before installing.

If the 9688Vit part number is not available or you need a nearby size, send us the dimensions of the old seal —shaft diameter, housing diameter and height— or a photo of the part. With that data we look for the equivalent in the same series or in another brand we sell. We can also advise you if the housing accepts a seal of a different height or if it is better to change the lip design.
