The DBH 8623Sil radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 68.70 mm shaft diameter, 90.50 mm housing bore and 7.50 mm height make it suitable for equipment where axial space is limited. 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 DBH line, identified with the code 8623Sil. According to the data sheet, it corresponds to a shaft of 68.70 mm diameter, a housing bore of 90.50 mm and a total height of 7.50 mm. The Lx-H-H design indicates a configuration with a sealing lip, reinforcing case and secondary exclusion lip, intended for continuous service in the presence of oils or greases.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is twofold: to prevent lubricant leaks to the outside and to block the entry of dust, water or particles that accelerate wear on bearings and gears. In industrial plants, they are commonly found in equipment operating at moderate speeds and temperatures within the usual range of standard elastomers.

To install a seal, check that the shaft has no burrs or marks that could damage the lip, lubricate the sealing edge and use an installation tool that presses on the metal case, never on the lip. Selection depends on peripheral speed, working temperature and the type of fluid. If the shaft shows wear, it is advisable to consider an alternative size or a seal with an offset lip.

To quote the code 8623Sil, send us the dimensions of your shaft and housing. At MR Accesorios Industriales we check the data against the manufacturer's data sheet to offer you the compatible alternative. We can also review whether your application requires a special design, such as a double lip or a high-temperature-resistant material.

Before replacing a seal, check the condition of the shaft surface and the housing: a scratched surface or excessive play shortens the life of the new seal. If you have doubts, send a photo or the drawing of the sealing area. Our technical team helps you interpret the dimensions and define the right replacement so the equipment can operate again without leaks.
