The DBH 5909 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its Lx design, with an elastomer lip and metal reinforcement, makes it suitable for rotating shafts in industrial equipment. It is used in gearboxes, pumps, electric motors and transmissions where bearings and gears must be protected. MR Accesorios Industriales carries this official brand and advises you on choosing the correct size.

This item is a DBH 5909 radial shaft seal, identified by its designation 5909. Its dimensions are shaft (d) 115 mm, housing (D) 140 mm and height (h) 13.00 mm, with an Lx design. The Lx design corresponds to a single-lip seal with a metal case and elastomer lip, intended for rotating shafts with lubrication. The 5909 nomenclature follows the DBH numbering system for metric-size seals. It is important to verify that the shaft diameter and housing diameter match these values before mounting.

Typical applications for a seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, drive shafts and continuous process equipment. In all cases it fulfills the function of retaining the oil or grease inside the assembly and preventing the entry of external contaminants, extending the life of bearings and gears. It is also used in equipment in the food, chemical and water treatment industries, where reliable sealing is critical to avoid leaks and unplanned downtime.

To mount this seal correctly, verify that the shaft has no burrs or marks and that the sealing surface is clean and lubricated. The housing must be free of debris and have the proper chamfer so as not to damage the lip during insertion. It is recommended to use a mounting tool that presses on the outer diameter and never on the lip. Seal selection must consider shaft speed, working temperature and the type of lubricant; if in doubt, consult our technical team.

If you need an equivalent or a nearby size, the most practical thing is to send us the 5909 part number or the current dimensions of the seal to be replaced: shaft diameter, housing diameter and height. With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the mounting space allows any variation. Remember that the 5909 designation is specific to DBH, so do not cross-reference it directly with other systems without verifying.
