MR Accesorios Industriales supplies this official brand and advises you on choosing the correct oil seal for your equipment.

This item is a DBH 1378 radial shaft seal, with designation 1378. Its dimensions are: shaft diameter (d) 28 mm, housing diameter (D) 38 mm and height (h) 10.00/15.00 mm. The A 135 design corresponds to a single-lip seal with spring, intended for rotating shafts. The variable height allows it to be adapted to housings with different mounting depths, as long as the shaft and housing dimensions are respected. It is a common replacement part in industrial equipment requiring lubricant containment.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission equipment. In all cases, its function is to prevent oil or grease leaks and protect the bearings from the ingress of dust, water or particles. Due to its compact size, it is used in low and medium power equipment. It is important to verify that the shaft and housing do not show excessive wear to ensure effective sealing.

To install this oil seal, verify that the shaft has the appropriate hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The 10/15 mm height allows you to choose the position according to the housing depth. If the shaft is damaged, consider a wear sleeve. Selection must take into account speed, temperature and type of lubricant. If in doubt, consult our technical team.
