The DBH 8257 radial shaft seal is a lip seal that prevents lubricant leaks and the entry of contaminants on rotating shafts. Thanks to its compact dimensions, it is used in power transmission equipment and small mechanisms where space is limited. MR Accesorios Industriales carries this official brand and advises you so that you choose the right seal according to the shaft size, the housing and the working conditions.

This item is a DBH 8257 radial shaft seal, with the following dimensions: shaft diameter 4.80 mm, housing diameter 22.00 mm and height 7.00 mm. The Ls design corresponds to a seal with a sealing lip and spring, intended for rotating shafts. The code 8257 identifies this specific size within the DBH line. Before installing it, verify that the dimensions match your equipment's shaft and housing, since even a minimal difference can affect sealing.

It is used in applications where oil or grease must be retained and dust or water excluded, such as gear reducers, pumps, electric motors, transmission shafts and mechanisms of agricultural or industrial machinery. It also appears in low-power equipment and in assemblies where the shaft rotates at moderate speeds. It is a wear part that should be checked periodically to avoid lubricant loss and greater damage to bearings and gears.

To select the right seal, take into account the shaft diameter, the housing diameter, the height and the design type. The Ls design is suitable for rotating shafts with lubrication and requires a polished shaft surface free of burrs. When installing it, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the shaft shows wear, evaluate a nearby size or a seal with an additional lip.

If you need an equivalent or a close size, send us the code 8257 or the dimensions of the original seal (shaft diameter, housing and height) via WhatsApp. At MR Accesorios Industriales we can look for alternatives within the DBH line or from other brands we carry. We also help you identify the seal from a sample or from the equipment's technical data sheet. The more data you give us, the more accurate the proposal will be.
