It is mounted in gear reducer cases, pumps, electric motors and industrial equipment in general. Its dimensions are 54 mm shaft diameter, 80 mm housing diameter and a height of 11.10/16.60 mm, with design A 074-Bidi. MR Accesorios Industriales sells this brand and advises you on choosing the right seal for your application.

This item is a radial shaft seal from the brand DBH, identified by part number 8839. Its standard dimensions are: shaft diameter 54 mm, housing diameter 80 mm and height 11.10/16.60 mm. Design A 074-Bidi indicates a double-lip configuration, which improves sealing against external contaminants. The sealing lip runs on the rotating shaft, while the outer diameter fits into the housing. It is a standard replacement part for industrial maintenance.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, its function is to confine the oil or grease and protect the bearings and bushings from the entry of dirt. It is commonly found in production lines, food plants, the chemical industry and road equipment. It is always advisable to verify the compatibility of the lip material with the lubricant and the operating temperature.

For installation, make sure the shaft has no burrs or marks that could damage the lip. Lubricate the seal with the same oil or grease used in the application before inserting it. The housing diameter must be clean and free of old sealant residue. The 11.10/16.60 mm height corresponds to a profile with a lip section and body; respect the housing depth so the seal seats correctly. If the shaft shows wear, consider a repair sleeve or an alternative size.
