The DBH 5144Sil radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 45 mm shaft diameter, 72 mm housing diameter and 10 mm height, it is press-fitted into crankcases, gearboxes and motors. It is a key component for the service life of bearings and power transmission systems.

This item is a DBH radial shaft seal, designation 5144Sil. The Lz design indicates a configuration with a sealing lip and a spring that ensures continuous contact on the shaft. Its dimensions are 45.00 mm shaft diameter (d), 72.00 mm housing diameter (D) and 10.00 mm height (h).

Radial shaft seals like this one are used in a wide variety of equipment: gear reducer boxes, pumps, electric motors, compressors, transmission shafts and agricultural or industrial machinery. Their mission is twofold: to retain the oil or grease of the bearing and to block the ingress of external contaminants. In environments with dust, water or chips, a seal in good condition makes the difference in the durability of bearings and gears.

To install a seal, you must verify that the shaft has no burrs or excessive wear in the contact area, and that the housing is clean and free of dents. The seal is pressed in, always perpendicular to the shaft, using a tube or spacer that rests on the metal edge, never on the lip. Before installing, lubricate the lip with the same oil or grease used in the equipment. If the shaft has a deep groove, consider a wear sleeve or a nearby size.

If you need an equivalent seal or a different size, the most practical thing is to send us the complete part number, a photo of the part and the dimensions measured with a caliper. 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 housing or shaft have unusual tolerances. Let's not improvise: a wrongly measured dimension can cause leaks or a forced installation.
