The DBH 8225 radial shaft seal is a lip seal designed for rotating shafts of 105 mm diameter, with a 130 mm housing and 18 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, which must be ground and lubricated. It is a common replacement part in pumps, gearboxes and power transmission equipment.

This item is a radial shaft seal from the DBH line, identified by the code 8225. According to the product page data, it corresponds to a shaft of 105 mm diameter (d), a housing of 130 mm (D) and a total height of 18.00 mm (h). The indicated design is A 123, a single-lip profile with a spring that ensures continuous contact on the shaft. DBH is a brand that MR carries, so the replacement is available under that designation and its standardized dimensions.

Typical applications for a seal of this size include centrifugal pumps, gearboxes, mixers, conveyors and process equipment where the shaft rotates inside a fixed housing. In these assemblies, the seal separates the oil or grease from the outside environment and extends bearing life. It is also used in large electric motors and machine tools that require constant lubricant containment.

To select correctly, verify that the shaft, housing and height dimensions match those of the original seal. 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 used in the equipment, insert the seal perpendicularly and tap only on the outer ring. If the shaft shows wear, consider a repair sleeve or an alternative size.

Send us the data of the old seal: shaft diameter, housing diameter and height. With those three dimensions we can look for an equivalent in the same DBH line or in another brand we carry. We can also advise you if the A 123 design is not suitable for your application and a different lip profile is better.
