The DBH 8423 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 42 mm shaft diameter, 55 mm housing diameter and 9 mm height make it suitable for gearboxes, pumps and medium-sized electric motors. The DBH brand is a brand that MR supplies, with options for replacement and made-to-size orders.
This item is a DBH 8423 radial shaft seal with the following dimensions: shaft diameter (d) 42 mm, housing diameter (D) 55 mm and height (h) 9.00 mm. The Mx design indicates a configuration with a single sealing lip and metal body, suitable for applications requiring sealing against oils and greases. The designation 8423 identifies the exact size within the DBH line, and it is the reference you will use to order it or look for an equivalent.
Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, the oil seal prevents lubricant leaks and the entry of dust or moisture into the bearing or shaft. It is commonly found in industrial machinery, process equipment and vehicles, where preventive maintenance requires replacing the seal when a leak or visible wear appears.
To install the oil seal correctly, check that the shaft measures 42 mm and the housing 55 mm, with a height of 9.00 mm. The shaft surface must be clean, free of burrs or marks, and lubricated before inserting the oil seal. The lip must face the side of the fluid to be retained. If the shaft shows wear, consider an oil seal with an auxiliary lip. Always confirm the temperature and the type of lubricant against the manufacturer's data sheet.
If you need an equivalent, the most practical thing is to send us the code 8423 or the current dimensions (shaft diameter, housing and height). With that data we can search the DBH line or other alternatives that fulfill the same function. We can also advise you if space is limited or if the original oil seal has any special feature, such as a double lip or high-temperature-resistant material.
