For maintenance teams working on medium-size power transmission equipment, the DBH 8437 oil seal is a replacement part that keeps lubricant in and contaminants out. It fits a 53 mm shaft, a 75 mm housing bore and has a 12.00 mm height, with a Kz design. MR supplies this seal as part of its seals and oil seals line for maintenance and repair.
The 8437 code identifies a radial shaft seal from DBH. Its key measurements are: shaft 53 mm, housing bore 75 mm, height 12.00 mm. The Kz design refers to a lip seal with a metal case, intended for rotating shaft applications. Because the part number is the original one, finding a replacement is straightforward when you match the code.
Seals of this size appear in gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment with 53 mm shafts. Industries such as food processing, chemical, petrochemical and water treatment rely on them to stop oil or grease from escaping and to keep bearings free from dust, water or particles. Mobile equipment and agricultural machinery with continuously rotating shafts also use this type of seal.
When installing a radial shaft seal, check that the housing and shaft are clean and free of burrs or scratches. Lubricate the lip before pressing it into place. The Kz design works well in moderate pressure conditions and needs a seat that is perpendicular to the shaft. If the old seal failed from wear, inspect the shaft surface and the housing before fitting the new one.
To request an equivalent, provide the 8437 code or the shaft, housing and height dimensions of the original seal. MR can quote the DBH series and compatible alternatives. The team can also tell you if the Kz design is not right for your equipment and you need a different lip profile or material. Quotes are handled by WhatsApp or email.
