The DBH 9089 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 30 mm shaft diameter, 38 mm housing bore and 7 mm height make it suitable for gearboxes, pumps and compact electric motors. Its Lx design combines a sealing lip with a dust lip, which improves protection in dusty or dirty environments. MR Accesorios Industriales supplies this official brand so you can replace worn seals with a reliable alternative.

This item is a radial shaft seal from the DBH brand, identified by part number 9089. According to its attributes, it is manufactured for a 30 mm diameter shaft, a 38 mm housing bore and a total height of 7.00 mm. The Lx design indicates that it has a main sealing lip and a secondary exclusion lip, mounted on a metal body that is press-fitted into the housing. This configuration is typical of seals that must operate in the presence of dust, chips or splashes, since the outer lip stops particles before they reach the sealing area.

The most common applications of a seal with these dimensions include gearboxes, centrifugal pumps, electric motors, compressors and machine tool spindles. In all cases, its function is to prevent oil or grease leaks and protect internal bearings from external contamination. Due to its compact size, it is found in equipment where radial space is limited and efficient sealing is required at moderate speeds. It is also used in belt or chain drives that need to keep lubrication contained.

To correctly select a seal, check that the shaft, housing bore and height dimensions match those of your equipment's housing and shaft. Shaft tolerance and surface finish are critical: a shaft that is too rough or worn can damage the lip prematurely. During installation, lubricate the lip with the same oil or grease it will seal, and insert the seal perpendicular to the shaft, without striking it directly. If the housing has burrs, clean and chamfer the entry so the lip is not cut. The Lx design requires the dust lip to face the exposed side.
