The DBH 8443 radial shaft seal is a lip seal that is mounted in the housing and closes against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. With dimensions of 100 mm shaft, 125 mm housing and 13 mm height, and Kx design, it is a replacement part for industrial equipment. MR Accesorios Industriales supplies this brand and advises you so that you choose the right oil seal for your equipment.

This item is a DBH 8443 radial shaft seal, identified by its designation 8443. Its dimensions are 100 mm shaft diameter (d), 125 mm housing diameter (D) and 13.00 mm height (h). The Kx design corresponds to a specific construction configuration within the DBH line. The oil seal combines an elastomeric lip with a metal body that fits into the housing; the lip runs on the shaft and seals by contact. Always verify these three dimensions before replacing an oil seal, because even a minimal difference prevents installation or causes leaks.

Typical applications for an oil seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases it fulfills the function of retaining the oil or grease inside the assembly and preventing contaminants from entering from outside. It is a critical part in environments with dust, humidity or frequent washing, where protecting the bearing or the bushing extends the service life of the equipment. If the oil seal fails, loss of lubricant accelerates wear of the moving parts.

To correctly select and install this oil seal, verify that the shaft diameter, housing diameter and height match the values indicated. The Kx design determines the shape of the lip and of the metal body, so it is not advisable to replace it with another design without evaluating the application. During installation, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicular to the shaft and avoid striking it. A damaged lip or a crooked installation causes premature leaks. If the shaft shows wear or roughness, consider a repair or an oil seal with a larger lip coverage.
