The DBH 8229Sil radial shaft seal is a lip seal that closes off the passage of lubricant and blocks the entry of dust, water or particles at the point where a shaft rotates inside a housing. Its Lx design and its dimensions of 39.42 mm shaft, 63.55 mm housing and 12.70 mm height place it in equipment where axial space is limited and a reliable seal is required. It is used in pumps, motors, gearboxes and reducers.

This oil seal is identified by its designation 8229Sil and by the Lx design, which corresponds to a sealing lip with a metal body and a geometry designed to retain lubricant against the shaft. The catalog dimensions are 39.42 mm shaft diameter (d), 63.55 mm housing diameter (D) and 12.70 mm height (h). Those three dimensions are what determine whether the seal fits your equipment: the shaft diameter governs the lip and the housing diameter governs the outer fit.

Typical applications of a radial shaft seal of these dimensions appear in centrifugal pumps, electric motors, gearboxes, mixers and transmission equipment where there is a shaft rotating inside a support. It is also found in agricultural machinery, process lines and industrial pumping equipment. In all cases it performs the same function: separating the lubricated side from the environment and preventing oil or grease from escaping through the shaft exit.

To install it, verify that the shaft diameter and surface condition are within acceptable limits, with no burrs or marks that could damage the lip. The housing must be clean and free of deformation, and the seal must go in perpendicular, without blows that could tilt it. Before fitting it, lubricate the lip with the same oil or grease used in the equipment. If the shaft shows wear in the contact area, consider a neighboring size or a seal with the lip in a different position.

If you need an equivalent or a close size, send us the part number 8229Sil together with the shaft, housing and height dimensions, and the brand of the equipment where it is installed. With that data we can look for an alternative within the DBH line or from other brands we carry, always confirming the technical data sheet before offering it. The more complete the information about the assembly, the more accurate the proposal will be.
