For maintenance teams working with small gearboxes, pumps and electric motors, the DBH 6258Sil is a radial shaft seal that keeps lubricant in and contaminants out. It fits a 20.00 mm shaft, a 30.00 mm housing bore and a 5.00 mm height, and its Ls design combines a sealing lip with a metal case for press fitting into the housing.
Reading the code helps when you are checking a bill of materials or a nameplate. DBH 6258Sil identifies the seal itself; the three figures that follow in the designation describe shaft, housing and height. In this case: shaft 20.00 mm, housing 30.00 mm, height 5.00 mm. The Ls suffix tells you the seal has a lip and a metal outer body, so it is installed by pressing it into the housing rather than onto the shaft.
Seals in this size range turn up in gear reducers, pumps, motors, compressors and transmission shafts, where the goal is to stop oil or grease from escaping and to keep dust, water and particles away from bearings and bushings. The 5.00 mm height is useful when axial room is tight, which is common in compact drives and small mechanisms.
Selection comes down to three measurements first: shaft diameter, housing bore and available height. Then consider shaft speed, operating temperature and the lubricant in use. The Ls design works with rotating shafts under permanent lubrication. During installation, clean the housing, apply lubricant to the lip and use a tool that will not cut or distort the seal. If the shaft surface is worn, an auxiliary lip may be worth discussing.
If you are looking for a replacement, send the complete code plus shaft, housing and height dimensions, and a photo or sample of the original. That lets us check alternatives in the DBH line or in other brands we supply, and advise whether a different height or a special design will fit the mounting space.
