The DBH 9404 oil seal is a radial shaft seal with a 48 mm shaft diameter, 78 mm housing diameter and 8 mm height. Its Lx design combines a sealing lip with a dust lip, which improves protection against external contaminants. It is used in gearboxes, pumps, electric motors and power transmission equipment to retain oil or grease and prevent leaks. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal for your application.

The DBH 9404 is an Lx-type radial shaft seal with the following dimensions: shaft diameter 48 mm, housing diameter 78 mm and height 8.00 mm. The Lx design incorporates a main sealing lip and a secondary dust lip, which helps keep lubrication clean and extends the service life of the seal. The outer body is metal and the sealing lip is elastomer, although the exact formulation is confirmed against the manufacturer's data sheet. It is a standard replacement part for rotating shafts.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors, spindles and power transmission equipment. In all these cases, the seal retains the lubricant inside the assembly and prevents the ingress of dust, water or particles. It is also used in agricultural machinery, conveying equipment and hydraulic systems where reliable sealing is required on turning or rotating shafts.

To select the seal correctly, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The Lx design is suitable when there is exposure to dust or dirt, since the dust lip provides an additional barrier. During installation, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the shaft shows wear or roughness, consider repairing it or using a seal with a wider coverage lip.
