The DBH 6403 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of contaminants such as dust, water or particles. With dimensions of 48 mm shaft diameter, 80 mm housing diameter and 13 mm height, and an A 094 design, it is a common replacement part in industrial equipment. MR Accesorios Industriales carries this brand and can advise you so you choose the correct seal.

This item is a radial shaft seal from the DBH brand, identified by the code 6403. Its dimensions are: shaft diameter (d) 48 mm, housing diameter (D) 80 mm and height (h) 13.00 mm. The A 094 design corresponds to a specific construction configuration that defines the lip type and material. It is a sealing component for rotating shafts, not for reciprocating motion or high pressures. It is press-fitted into the housing and its flexible lip contacts the shaft to form the seal.

Typical applications for a seal such as the 6403 include gearboxes, pumps, electric motors, conveyor rollers and transmission equipment. In all cases, it protects bearings and gears from the ingress of dirt and prevents oil or grease leaks. It is commonly found in agricultural machinery, process equipment and continuous conveying systems. Its selection depends on shaft speed, operating temperature and the type of lubricant, among other factors.

To install a seal correctly, check that the shaft has no burrs or marks and that the contact surface is polished. Lubricate the lip before installation and make sure the housing is clean and undamaged. When selecting a replacement, in addition to the dimensions, take into account the lip material (NBR, FKM, etc.) and the spring type. If the original seal has a different designation, we can look for a compatible alternative with the same dimensions and performance.
