The DBH 5490 is a radial shaft seal that keeps lubricant in and contaminants out of gearboxes, pumps and other rotating equipment. Its Lz design pairs a main sealing lip with a secondary dust lip, so it holds up in dirty or dusty conditions. The size is 38.10 mm shaft, 63.55 mm housing and 9.52 mm height, a combination that is replaced often on industrial machines.
The part number 5490 belongs to the DBH line of radial shaft seals. Reading the dimensions: shaft diameter (d) 38.10 mm, housing diameter (D) 63.55 mm, height (h) 9.52 mm. The Lz designation tells you there are two lips: the primary one keeps oil in, the secondary one works as a dust lip to block particles from reaching the sealing area. An outer metal ring holds the elastomer firmly in the housing bore.
You will find this seal on input and output shafts of gearboxes, centrifugal pumps, mixers, conveyors and general transmission equipment. It also shows up in agricultural machinery, industrial washing systems and pumping setups exposed to dust or water. Because the 38.10 mm shaft size is common on European and American equipment, it is a frequently requested spare.
Before installing, confirm the shaft has the right hardness and surface finish, and that the housing bore is clean and free of burrs. Lubricate the lip, then press the seal in with a tool that contacts the outer diameter only, never the lip. If the application involves heavy vibration or misalignment, consider a stiffer design or an extra lip. Speed, temperature and the fluid being retained will determine the final choice.
For an equivalent, send the part number 5490 with the shaft, housing and height dimensions, plus the fluid type. With that information we can search for an alternative in the DBH line or from other brands we supply. We can also help if the housing has a recess or the shaft shows wear, so you get the right sealing solution.
