The DBH 6742 radial shaft seal is a lip seal fitted in the housing that closes onto the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 17 mm shaft, 40 mm housing and 8.50 mm height place it in small and medium-sized equipment. It is a wear part: when oil loss or dirt ingress appears, it is replaced. MR Accesorios Industriales carries this brand and helps you identify the correct size.

This item is a radial shaft seal from the DBH brand, identified with the code 6742. Its published attributes are: shaft diameter 17 mm, housing diameter 40 mm, height 8.50 mm and design Lx. The Lx design corresponds to a single-lip seal with a metal case and sealing lip, designed for rotating shafts with lubrication. Before fitting it, check that the housing is clean and free of burrs, and that the shaft shows no wear or scoring in the contact area.

Typical applications for a seal of this size include small centrifugal pumps, electric motors, compact gear reducers, gearboxes, mixers, power transmission equipment and process machinery in general. It is also used on fan shafts, compressors and pumping equipment where oil or grease needs to be contained and external contamination avoided. In all cases, the seal works as a dynamic barrier between the lubricated interior and the environment.

To correctly select a seal, the three dimensions must be respected: shaft diameter, housing diameter and height. In addition, the lip design must be compatible with the speed, temperature and type of lubricant in the equipment. If the shaft is worn, a repair sleeve or a seal with an additional lip can be considered. The shaft surface must have suitable hardness and roughness so that the lip seals without wearing prematurely.

If you cannot find the code 6742 or need a nearby size, send us the dimensions of the old seal or the code engraved on the part. You can also indicate the equipment where it is fitted and its brand. With that data, at MR Accesorios Industriales we look for the equivalent available in the brands we carry. If the seal has no legible code, measure the shaft, housing and height with a caliper and send us those values.
