The DBH 8406 radial shaft seal is a lip seal designed to stop oil or grease from escaping on rotating shafts and to prevent dust or water from entering the housing. It is fitted in pumps, motors, gearboxes and power transmission equipment, among other industrial applications. Its dimensions correspond to a 39.42 mm shaft, an 80.27 mm housing and a height of 14.25 mm, with A 055-R design. MR Accesorios Industriales sells this official brand and advises you on choosing the right seal for your equipment.

This item is a DBH radial shaft seal, identified with code 8406. Its dimensions are: shaft diameter 39.42 mm, housing diameter 80.27 mm and height 14.25 mm. The A 055-R design defines the lip geometry and the type of case. It is intended to retain lubricant and exclude contaminants on rotating shafts, with a construction that combines a flexible sealing element and a metal case that gives it rigidity and makes press-fitting into the housing easier.

Typical applications for a seal with these characteristics include centrifugal pumps, electric motors, gearboxes, speed reducers, compressors and power transmission equipment. In all cases, the seal protects bearings and gears from particles entering and prevents oil leaks. It is a critical part in industrial maintenance, since its failure can cause lubricant loss, premature wear of components and unplanned downtime.

To correctly select this seal, check that the shaft, housing and height dimensions match those of the equipment. The shaft surface must be free of burrs, with suitable hardness and roughness so as not to damage the lip. During installation, lubricate the lip with the same oil or grease used in the system, insert it perpendicular to the shaft and avoid hitting it. If the housing shows wear, consider using a seal with an oversized case or a repair sleeve.
