The DBH 1278Pol oil seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and stop the entry of dust, water or particles. Its design A 296 combines a sealing lip with a reinforced body, and its dimensions of 42 mm shaft, 76 mm housing and variable height of 13.50/19.00 mm place it in transmission equipment and industrial machinery where axial space is limited. MR Accesorios Industriales sells it as part of its seals line.
This DBH 1278Pol oil seal has a shaft diameter of 42 mm, a housing diameter of 76 mm and a height of 13.50/19.00 mm. Design A 296 corresponds to a radial shaft seal with a sealing lip and metal body, designed for rotating shafts. The double height indicates that the profile can fit housings with different mounting depths, as long as the lip rests correctly on the shaft. It is a common replacement part in gearboxes, pumps and transmission equipment.
Typical applications for this type of oil seal include gearboxes, electric motors, centrifugal pumps, conveyor rollers and belt or chain transmission equipment. In all cases, the oil seal protects the bearings and gears from the entry of contaminants and prevents oil or grease leaks. It is also used on fan shafts, mixers and machine tools where an economical and reliable seal is needed.
To select and mount an oil seal like the DBH 1278Pol, verify that the shaft and housing diameters match the indicated dimensions. The lip must be lubricated before mounting and the shaft must have a surface free of burrs or marks. The height 13.50/19.00 mm allows adaptation to housings of different depths, but it is important that the oil seal sits fully seated and is not exposed. If the shaft is worn, consider a repair sleeve or a neighboring size.
