The DBH 1312 oil seal is a radial shaft seal with design A 378 that fits housings of 90 mm diameter and 8 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles, protecting bearings and shafts in rotating equipment. It is a wear part that should be replaced when oil leakage or excessive play appears. MR Accesorios Industriales carries this official brand and advises you on choosing the correct seal for your application.

This DBH 1312 oil seal is identified by its designation 1312 and corresponds to design A 378. Its dimensions are: housing diameter 90 mm and height 8 mm. The A 378 series groups single-lip seals with spring, suitable for rotating shafts with lubrication. Always verify that the housing and shaft match these dimensions to avoid leaks.

Typical applications of a seal like the DBH 1312 include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal works on a rotating shaft and contains the oil or grease inside the assembly. It is also used to seal shaft passages in environments with moderate dust or humidity. If the equipment operates at high peripheral speeds or elevated temperatures, a specific lip compound should be evaluated.

To correctly install this seal, clean the housing and shaft, verify there are no burrs or scratches and lubricate the lip with the same oil used in the equipment. Insert the seal perpendicularly, without striking the lip, using a tube that supports the outer ring. Selection depends on shaft speed, working temperature and the type of fluid to be retained. If the original seal has a different design, we can look for an equivalent with the same housing and height dimensions.
