The DBH 5420Sil radial shaft seal is a lip seal that mounts on a 20 mm shaft and fits into a 47 mm bore, with a total height of 7 mm. Its Lx design combines a sealing lip with a spring that maintains pressure against the shaft, and an outer body that secures it in the housing. It is used to retain oil or grease and exclude dust and water in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this official brand.

This item is a radial shaft seal from the DBH line, identified with the part number 5420Sil. Its dimensions are: shaft diameter 20 mm, housing diameter 47 mm and height 7.00 mm. The Lx design corresponds to an oil seal with a sealing lip and spring, with a geometry that favors installation in tight spaces. The elastomer of the lip is formulated to resist mineral oils and greases, and the outer metal body ensures adequate interference in the housing.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission rollers. In all cases, its function is to prevent lubricant leaks and protect the bearings from contaminants entering. It is commonly found in equipment where the shaft rotates at moderate speeds and temperature conditions do not exceed the limits of the standard material. It is also used in agricultural and industrial machinery operating in environments with dust or humidity.

To correctly select this oil seal, verify that the shaft and housing dimensions match those indicated. Installation requires cleaning the surfaces, lubricating the lip and using an installation tool that avoids damaging the sealing edge. Shaft and housing eccentricity must remain within normal tolerances for radial shaft seals. If the equipment operates at high temperatures or high peripheral speeds, ask about variants with special materials.
