The DBH 5310 radial shaft seal is a lip seal that mounts on a 20 mm shaft and seals against a 42 mm housing bore, with a height of 7 mm. Its Lz design combines a sealing lip with a dust lip, which improves protection against dust and splashes. It is used in gearboxes, pumps, electric motors and transmission equipment to retain oil or grease and prevent the entry of contaminants.

This item is a DBH 5310 radial shaft seal, identified by its designation 5310. According to the product page data, it has a shaft diameter of 20 mm, a housing bore of 42 mm and a height of 7.00 mm. The Lz design indicates that it incorporates a main sealing lip and an auxiliary exclusion lip, intended for environments with dust or dirt. The elastomer and internal spring are not specified in the record, so they are confirmed against the manufacturer's data sheet at the time of inquiry.

Typical applications for a seal of these dimensions include small gearboxes, centrifugal pumps, electric motors, fan shafts and power transmission equipment. In all cases, the function is to retain the lubricant inside the assembly and block the passage of external particles. Due to its compact size, it is common in equipment where radial space is limited and reliable sealing is required at moderate speeds.

For installation, verify that the shaft and housing are clean, free of burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it and avoid striking it during placement. Seal selection must consider the rotation speed, operating temperature and the type of fluid to be retained. If the shaft shows wear, evaluate a repair size or a seal with the lip running on a different track.

If you need an equivalent or a nearby size, the most practical approach is to send us the code 5310 or the current dimensions (shaft, housing bore and height) along with a photo of the old seal. With that data we can look for an alternative within the DBH line or other brands we supply. We can also advise you if the Lz design does not suit your application and another type of lip is more appropriate.
