The DBH 1257Vit radial shaft seal is a lip seal designed for a 76.20 mm shaft, 95.40 mm housing and 17.00 mm height, with design A 407. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles, working against the rotating shaft. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings and gears must be protected. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal.

This item is a seal from the DBH line, identified by the code 1257Vit and design A 407. Its dimensions are shaft d 76.20 mm, housing D 95.40 mm and height h 17.00 mm. Design A 407 corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The elastomeric lip seals against the shaft surface and the spring maintains contact pressure. The outer metal case ensures a firm fit in the housing.

Typical applications for this seal include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all these cases, the seal prevents oil or grease leaks and blocks the entry of contaminants that accelerate wear on bearings and gears. It is also used in agricultural machinery, process equipment and hydraulic systems where reliable sealing is required at the shaft exit point.

To install this seal, verify that the shaft measures 76.20 mm and the housing 95.40 mm, with a suitable surface finish and no burrs. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, using an installation tube that presses on the metal case, never on the lip. If the shaft shows wear, consider a nearby size or a seal with the lip in a different position. Selection depends on the speed, temperature and type of lubricant in the equipment.
