The DBH 9919 radial shaft seal is a lip seal designed to be mounted on rotating shafts to prevent oil or grease leaks while blocking the entry of dust and contaminants. Its dimensions of 57 mm shaft diameter, 66.80 mm housing and 5.00 mm height make it suitable for equipment with compact mounting spaces. MR Accesorios Industriales carries this brand and advises you so you can choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified with the part number 9919. Its dimensions are: shaft diameter (d) 57 mm, housing diameter (D) 66.80 mm and height (h) 5.00 mm. The Mt design corresponds to a configuration with a sealing lip and metal body, designed to retain lubricant on rotating shafts. It is a common replacement part in gearboxes, pumps and electric motors, where axial space is limited and efficient sealing is required.

Typical applications for this seal include gear transmissions, centrifugal pump shafts, conveyor rollers and general machinery operating with 57 mm shafts. Its reduced height of 5 mm allows it to be installed in shallow housings, as long as the shaft and housing surfaces are in good condition. It is commonly found in equipment where worn seals showing lubricant loss or dirt ingress need to be replaced.

To mount this seal correctly, verify that the shaft has adequate hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip with the same oil or grease used in the application before inserting it, and use a mounting tool that presses on the outer diameter so as not to damage the seal. Selection must consider rotation speed, temperature and the type of fluid; if in doubt, consult us with your equipment data.

If you need a seal equivalent to the DBH 9919, the most practical approach is to send us the full part number, the shaft, housing and height dimensions, and a photo of the original part. With that data we can look for alternatives in other brands or series that fulfill the same function. We can also advise you if the mounting space allows any minimal variation in height or outer diameter.
