The DBH 8485 is a radial shaft seal built to sit in a machined housing bore and ride against a rotating shaft, holding lubricant in and keeping dust, water and particles out. Its designation number is 8485, and it comes in the Lx design. The three dimensions that define it are a 23.00 mm shaft, a 34.00 mm housing bore and a 6.00 mm height. It belongs to our line of seals and oil seals.

Reading a seal designation starts with the number: 8485 identifies this size within the DBH range. The three figures that follow describe where it fits: the shaft it contacts measures 23.00 mm, the bore it presses into measures 34.00 mm, and its height, or width across the outside, is 6.00 mm. The Lx designation describes the profile, which in this case is a single lip with a spring.

You will find this type of seal in gearboxes, pumps, electric motors, compressors, rollers and other transmission equipment. It does two jobs at once: it keeps oil or grease where it belongs inside the assembly, and it blocks contaminants from working their way in from outside. Where a shaft turns continuously, where there is vibration, or where dust is present, the seal is among the first parts to wear, so matching the original size matters when you replace it.

Three checks cover most of the selection work. The shaft diameter has to match the lip, the housing bore has to be the right size and finish, and the height has to let the seal seat without distorting. Before installation, clean the shaft and look for burrs or deep marks, then lubricate the lip. To pull the old seal, use a puller or a flat-tip screwdriver and keep the bore edge intact.

If you want a seal from another brand, send the complete part number, the shaft, bore and height figures, and a photo of the part you are replacing. With that information we can look for an alternative within the DBH line or among the other brands we supply. We can also tell you whether the Lx profile suits your application or whether a different lip type would serve you better.
