The DBH 9837 radial shaft seal is a lip seal mounted in the housing of a piece of equipment to retain lubricant and prevent contaminants from entering. With dimensions of 73 mm shaft, 90 mm housing and 8 mm height, and a Kx design, it is used on rotating shafts of pumps, motors, gear reducers and transmission boxes. MR Accesorios Industriales sells this brand and advises you so you can choose the right seal for your application.

This item is a DBH 9837 radial shaft seal, identified by its numeric designation. Its main attributes are: shaft diameter (d) of 73 mm, housing diameter (D) of 90 mm, height (h) of 8.00 mm and Kx design. The Kx design corresponds to a configuration with a sealing lip and a specific profile that allows it to adapt to shafts with slight misalignment or vibration. The seal is made with elastomers and a metal case that gives it rigidity to keep the lip in contact with the shaft.

Typical applications for this seal include centrifugal pumps, electric motors, speed reducers, gearboxes and power transmission equipment. In all these cases, the seal retains the oil or grease inside the assembly and prevents dust, water or external particles from entering the mechanism. It is a wear part that should be replaced when leaks or abnormal noises are detected in the sealing area.

For installation, check that the shaft and housing are clean, free of burrs and scratches, and that the dimensions match those of the seal: 73 mm shaft, 90 mm housing and 8.00 mm height. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and place the seal perpendicular to the shaft so as not to damage the lip. If the shaft shows wear, consider a repair sleeve or a seal with an auxiliary lip.
