The DBH 5445Sil radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and water from entering rotating shafts. With dimensions of 17.50 mm shaft, 28.50 mm housing and 7.00 mm height, and Lx design, it is press-fitted into crankcases, covers and gearboxes. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your equipment.

This item is a DBH 5445Sil radial shaft seal, identified by its commercial designation. Its dimensions are 17.50 mm shaft diameter, 28.50 mm housing diameter and 7.00 mm height. The Lx design corresponds to a single-lip seal with spring, designed to retain lubricant in one direction and exclude contaminants from the opposite side. The 5445Sil nomenclature makes it quick to locate in the catalogue and compare it with other alternatives from the same brand.

Typical applications for a seal of this size include small electric motors, centrifugal pumps, speed reducers, compressors, machine tools and power transmission equipment in general. It is also used on fan, mixer and conveyor shafts where there is continuous rotation and the presence of oil or grease. As a wear component, it should be checked at every preventive maintenance interval to avoid lubricant loss and greater damage to bearings and gears.

For proper installation, check that the shaft has no burrs or wear and that the surface where the lip rests is clean and lubricated. The housing must be in good condition, free of impacts, and the seal is pressed in with a tube of the appropriate diameter, never by striking the lip. If the equipment operates with high vibration or temperature, consider a more resistant design. The final selection depends on shaft speed, lubricant type and working pressure.

If you need an equivalent or a nearby size, send us the code 5445Sil or the dimensions of your current seal: shaft diameter, housing diameter and height. With that data we look for alternatives in the same brand or in others we supply, respecting the design and lip type. We can also advise you if the space allows a seal of a different height or if it is better to move to a design with additional dust protection.
