The DBH 5440 is a radial shaft seal built to keep lubricant in and contaminants out of rotating assemblies. It fits a 127 mm shaft, a 152.40 mm housing bore and a 14.28 mm width, and its Lz lip profile handles moderate dust exposure. MR Industrial Accessories supplies this seal so maintenance teams can match a standard size without guesswork.

The seal carries the DBH designation and the code 5440. Its three key measurements are shaft 127 mm, housing 152.40 mm and height 14.28 mm. The elastomer resists oil and grease, while the metal case gives the seal enough stiffness to press into place. The Lz lip is intended for shafts turning at moderate speeds where a durable barrier is needed.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. In each case the seal stops lubricant from escaping and blocks abrasive particles that would otherwise shorten bearing and gear life. Agricultural and industrial machines that see dust or moisture are also common hosts for this seal. The 127 mm shaft dimension puts it in medium- and high-power drives.

Installation calls for a shaft that is hard enough and smooth enough, with no burrs or marks that could cut the lip. Coat the lip with the same oil or grease used in the machine before you push the seal in. The housing bore must be clean and undistorted, and the seal should go in with even pressure, never by hitting the lip. When choosing a seal, check rotation speed, operating temperature and the fluid being retained. A worn shaft may call for a repair sleeve.

If you need a replacement for the DBH 5440, send the complete code or the dimensions of the part you are running. MR Industrial Accessories can look for alternatives in the same brand or in other lines we supply, keeping the dimensions and design in mind. We can also tell you whether the mounting space allows a variant with an extra lip or a different material.
