The DBH 5959 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 44.45 mm shaft, 71.33 mm housing and 7.14 mm height place it in equipment with medium-section shafts. It is used in pumps, electric motors, gearboxes and transmissions where the lubricant must stay inside and contamination outside.

This item is a DBH 5959 radial shaft seal, identified by its designation 5959. Its dimensions are 44.45 mm shaft diameter, 71.33 mm housing diameter and 7.14 mm height, with Lx design. The Lx design corresponds to a single-lip seal with a spring, intended for rotating lubricated shafts. The DBH nomenclature groups seals with a standard profile for press fitting into a cylindrical housing. Always confirm these dimensions against the drawing or the original part before ordering.

Typical applications for a seal of these dimensions appear in centrifugal pumps, electric motors, gear reducers, transmission shafts and process equipment. In all cases it performs the same function: prevent oil or grease leaks and stop dirt from reaching the bearing or bushing. It is also found in agricultural machinery, washing equipment and conveying systems, where the working environment is demanding and the seal is the first barrier.

To select it properly, verify the shaft diameter, the housing diameter and the available height. The lip must rest on a ground surface free of grooves; if the shaft is worn, it is worth considering a wear sleeve or a nearby size. During installation, lubricate the lip, insert the seal perpendicular to the shaft with a suitable tool and avoid hitting it sideways. Speed, temperature and the type of lubricant determine the lip material: consult us on those data.

If you need a nearby size or an equivalent, send us part number 5959 together with the measurements taken on the machine. A photo of the old seal, the housing drawing or the make and model of the equipment also works. With that data we review alternatives within the DBH line and from other brands MR carries, and we confirm which option fits without modifying the installation. The number does not have to be identical: many times the actual size is what matters.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals. If this seal is for equipment in operation, write to us on WhatsApp with the part number and dimensions, and we will send you the quote. We can also advise you on the lip material and the spring according to the fluid and working temperature. More than 80 years serving industry taught us that a well-taken measurement saves downtime.
