The DBH 1028 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the ingress of dust and water in equipment with a rotating shaft. Due to its dimensions of 72.24 mm shaft, 100.05 mm housing and 12.70 mm height, it is used in gearboxes, pumps and industrial transmissions. MR Accesorios Industriales carries this official brand and advises you on choosing the correct seal for your application.

This item is a DBH radial shaft seal, identified by the designation 1028. Its dimensions are 72.24 mm shaft diameter (d), 100.05 mm housing diameter (D) and 12.70 mm height (h). The Mx design corresponds to a configuration with a sealing lip and metal body, designed to retain lubricant and exclude contaminants on rotating shafts. It is a direct replacement part for equipment already using this size, and is available as part of the seal line that MR Accesorios Industriales carries.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, transmission shafts and process equipment with oil or grease lubrication. In these assemblies, the seal works on a shaft rotating inside a fixed housing, and its function is twofold: keep the lubricant in and prevent particles, water or steam from entering. Due to its dimensions, it is common in medium-sized industrial machinery, where radial space is limited.

To install a radial shaft seal, it is advisable to check the condition of the shaft and housing: there must be no burrs, scratches or wear that could damage the lip. The shaft surface where the lip rests must be polished and lubricated before inserting the seal. It is recommended to use a tube or socket of the appropriate diameter to push evenly, without striking the lip. If the equipment operates with high vibration or temperature, it is advisable to evaluate the lip material and spring type with the supplier.

If you need an equivalent seal or a nearby size, the most practical approach is to send the code 1028 or the dimensions of your shaft, housing and height. With that data, an alternative can be found within the same DBH line or other brands that MR carries. Sending a photo of the old seal and the housing also helps, as it confirms the design and avoids installation errors. The goal is for you to receive the correct part without complications.
