The DBH 5312 oil seal is a radial shaft seal with a 25 mm shaft diameter, 42 mm housing diameter and 6 mm height, in Lx design. It is used to retain lubricant and exclude contaminants on rotating shafts, inside gearboxes, pumps, motors and reducers. Its flexible lip runs on the shaft and maintains sealing under continuous rotation. At MR Accesorios Industriales we carry it as part of our seals and oil seals line for maintenance and replacement.

The DBH 5312 is a radial shaft seal with the following dimensions: shaft diameter 25 mm, housing diameter 42 mm and height 6.00 mm. Its Lx design corresponds to a seal with a sealing lip and metal case, designed to be press-fitted into the housing and seal against the shaft. These dimensions are those shown in the designation and must match the housing and shaft of the application to ensure a correct fit.

It is used in equipment with rotating shafts where oil or grease must be contained and dust, water or particles kept out. It appears in gearboxes, pumps, electric motors, reducers, rollers and transmissions. It is a wear part that is replaced during preventive maintenance or when lubricant leaks are detected. It is also chosen in repairs to restore the original sealing of the assembly.

To select the seal, verify that the shaft diameter, housing diameter and height match those of the DBH 5312. Check the condition of the shaft surface: it must not have burrs or pronounced wear in the lip contact area. When installing, lubricate the lip and the shaft, and insert it perpendicular to the housing with a suitable tool, without striking the lip. If the shaft has a groove or wear, evaluate an alternative size or a seal with the lip in another position.

If you need an equivalent seal, the most practical thing is to send us the DBH 5312 part number or the current dimensions (shaft, housing and height). With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the housing or shaft have unusual tolerances. The idea is for you to have a reliable option without stopping maintenance.
