When a rotating shaft starts weeping oil, the fix usually comes down to one small component: the radial shaft seal. The DBH 5158 is a single-lip seal built to hold lubricant in and keep dust and water out. Its size is given as 24 mm for the shaft, 37 mm for the housing bore and 7 mm for the height, and it uses the Lx design. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your machine.

Reading the part number is the fastest way to identify a replacement. In the DBH line, 5158 points to this specific size and design, so if the old seal still has its number stamped on it, or the equipment manual lists it in the parts breakdown, you can match it directly. The three figures that matter are d = 24.00 mm (shaft), D = 37.00 mm (housing) and h = 7.00 mm (height). The Lx designation tells you it is a single-lip seal with a spring, made for lubricated rotating shafts.

You will find seals like this one in gearboxes, pumps, electric motors, transmission shafts and process equipment. The job is always the same: keep the oil or grease where it belongs and stop outside contamination from reaching the bearing. For maintenance teams in plants and production lines, keeping a correct replacement on hand is what prevents a minor leak from turning into a messy, costly repair.

Installation decides how long the seal lasts. Measure the shaft and bore first and confirm they match the nominal values. Lubricate the lip before the shaft goes in, and drive the seal with a tube that contacts the outer ring only, never the lip. Look over the shaft surface for burrs or wear at the sealing area, since either one will cut seal life short. If the equipment runs hot or with heavy vibration, ask about alternative compounds.

To get a quote, send a photo of the part together with the shaft, housing and height measurements. The team checks the data and can offer equivalent options from the same brand or other compatible choices, including different elastomer grades depending on the fluid and the working temperature.
