The DBH 5310 is a radial shaft seal with an Lz design, sized for a 20 mm shaft, a 42 mm housing bore and a 7 mm width. The Lz configuration means it has both a main sealing lip and an additional dust lip, which helps keep dust and splashes out. It is typically used in gearboxes, pumps, electric motors and transmission equipment to hold oil or grease in and keep contaminants out.
This seal carries the designation 5310. Its dimensions are shaft 20 mm, housing 42 mm and width 7.00 mm. The Lz design tells you it has a primary sealing lip plus an auxiliary exclusion lip, so it is suited to environments where dust or dirt is present.
You will find seals of this size in small gearboxes, centrifugal pumps, electric motors, fan shafts and power transmission units. In each case, the seal keeps lubricant inside the assembly and blocks external particles. Because it is compact, it fits equipment with limited radial space that still needs reliable sealing at moderate speeds.
Before installing, make sure the shaft and housing are clean and free of burrs or marks that could harm the lip. Apply some of the same oil or grease used in the equipment to the lip, then insert the seal without striking it. When selecting a seal, consider rotation speed, operating temperature and the fluid being retained. If the shaft is worn, look at a repair size or a seal that positions the lip on a different track.
If you need an equivalent, send us the part number 5310 or the current dimensions (shaft, housing and width) along with a photo of the old seal. With that information we can search for an alternative in the DBH line or other brands we supply. We can also let you know if the Lz design is not the best fit and a different lip type would work better.
