The DBH 5522 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —36.91 mm shaft, 52.37 mm housing and 4.36 mm height— correspond to a specific application, so it is used as a direct replacement in equipment that requires that geometry. MR Accesorios Industriales carries this brand and helps you identify the correct seal when the original no longer has a legible identification.

This item is a DBH 5522 radial shaft seal, identified by its designation 5522. It runs on a shaft of 36.91 mm diameter, fits into a bore of 52.37 mm and has a height of 4.36 mm. The Mt design indicates a single-lip configuration with spring, suitable for rotating shafts with lubrication. It is a thin-section seal, intended for reduced axial spaces where a standard-height seal does not fit.

It is used in gearboxes, pumps, electric motors, compressors and transmission equipment where a shaft rotates inside a housing and the oil needs to be separated from the environment. It also appears in applications exposed to dust or water, where the exclusion lip prevents particles from entering. It is common to find it in imported machinery with inch dimensions converted to millimeters, hence the decimal values.

To select a seal you must verify three things: shaft diameter, housing diameter and available height. If the shaft is worn or scored, the new lip may not seal even if the dimension matches. The shaft surface must be polished and free of burrs, and it is advisable to lubricate the lip before installing it. The Mt design is installed with the lip facing the lubricant side, unless the equipment indicates otherwise.

If you cannot find the code 5522 or you need a nearby size, send us the dimensions of the old seal —shaft, housing and height— or a photo with a caliper next to it. With that data we look for the equivalent in the same brand or in another with similar characteristics. We can also evaluate design variants if the space allows it. The more accurate the measurement, the faster we reach the replacement.

MR Accesorios Industriales carries the DBH brand and has more than 80 years of experience in bearings, seals and power transmission.
