The DBH 5671 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating shafts. With dimensions of 25.40 mm shaft, 31.75 mm housing and 3.20 mm height, and an Mt design, it is mounted in crankcases, covers and flanges where axial space is limited. MR Accesorios Industriales carries this official brand so you can handle replacements with the exact size.

This item is a radial shaft seal from the DBH line, identified by part number 5671. Its dimensions are 25.40 mm shaft diameter, 31.75 mm housing diameter and 3.20 mm height. The Mt design corresponds to a configuration with a sealing lip and metal body, intended to retain oil or grease in low-pressure applications. It is a direct replacement part: it is installed in the housing and seals against the rotating shaft.

Radial shaft seals like this one are used in gearboxes, electric motors, pumps, compressors and power transmission equipment. They also appear in spindles, rollers and machine tool shafts where lubricant must be contained and bearings protected from dust or moisture. Because of its reduced height, the 5671 is often used in thin covers or in spaces where a larger-section seal does not fit.

To install it, make sure the shaft and housing are clean, free of burrs and scratches, and lubricate the lip before inserting it. The seal must sit square, without striking the lip during installation. If the shaft shows wear, consider a nearby size or a seal with the lip in a different position. Selection depends on speed, temperature and lubricant type, data that should be checked against the manufacturer's product page.

If you need an equivalent or a close size, send us part number 5671 or the shaft, housing and height dimensions. With that data we can look for alternatives in the same DBH line or in other brands we carry. We can also advise you if the Mt design is not right for your application and a different lip type or material is needed.
