The DBH 8256 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Thanks to its compact dimensions, it is used in equipment where axial space is limited and a reliable seal is required. MR Accesorios Industriales carries this brand as part of its seals and oil seals line, with technical advice to choose the right size according to the housing and the shaft.

This item is a radial shaft seal from the DBH brand, identified by the code 8256. Its dimensions are: shaft diameter 17 mm, housing diameter 25 mm and height 4.00 mm. The Lt design corresponds to a single-lip configuration with spring, suitable for rotating shafts with lubrication. The manufacturer's nomenclature makes it easy to locate in the catalog and verify compatibility with the existing housing.

Seals of this size are used in small electric motors, pumps, gear reducers, compressors and power transmission equipment. Their function is twofold: to prevent oil or grease leaks to the outside and to block the entry of dust, water or particles that accelerate bearing wear. In applications with 17 mm shafts, they are commonly found in compact gearboxes and drive mechanisms.

To install a seal, check that the shaft has no burrs or marks that could damage the lip, lubricate the edge before inserting it and seat it perpendicular to the shaft. Selection depends on rotation speed, working temperature and the type of lubricant. If the equipment operates with high vibration or pressure, it is advisable to evaluate a design with a metal case or an auxiliary lip.
