The DBH 5505 radial shaft seal is a lip seal that mounts on the shaft and inside the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 30.10 mm shaft, 42.86 mm housing and 6.35 mm height place it in compact-section applications. It is a wear part: when the lip hardens or a leak appears, it is replaced. MR Accesorios Industriales carries this official brand and helps you identify the correct size.

This item is a seal from the DBH line, identified with code 5505. Its published attributes are: shaft diameter 30.10 mm, housing diameter 42.86 mm and height 6.35 mm. The indicated design is Mz, a single-lip configuration with a metal body that fits straight housings. These dimensions are what define the mounting: the inner diameter works on the shaft and the outer one seats under pressure in the cavity. If your equipment calls for another size, the equivalent in the same series can be looked up.

Radial shaft seals of this section are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where there is continuous rotation and the presence of oil or grease. They also appear in agricultural machinery, conveyors and washing equipment, where in addition to retaining lubricant they must hold back dust and water. The choice of lip material and spring depends on the fluid, temperature and rotation speed, data worth having on hand when requesting a quote.

To mount a seal you must verify that the shaft has no burrs, wear or scoring, and that the housing is clean and free of deformation. The lip is lubricated before inserting it and seated well straight so as not to damage it. The 6.35 mm height requires a cavity with the proper depth. If the shaft shows a marked groove, it is sometimes advisable to shift the seal slightly or consider a repair sleeve. At MR Accesorios Industriales we advise you according to the condition of your equipment.

With that data we look for the equivalent seal within the DBH line or from other brands we carry. We can also check whether the Mz design is the most suitable or whether it is better to switch to another profile for your application.
