The DBH 6603 is a radial shaft seal sized for a 120 mm shaft, a 150 mm housing bore and a 12 mm height. Its job is to keep lubricant where it belongs and to keep dust, water and other contaminants out of the bearing or bushing area. Because the seal presses into the housing and rides on the rotating shaft, the finish and condition of both surfaces have a direct effect on how long it lasts.

This seal belongs to the DBH line and carries the designation 6603. The dimensions are shaft 120 mm, housing 150 mm, width 12.00 mm. Its design type is Lx, which describes how the lip and the outer body are built. It is a single-unit replacement part intended for equipment already built to this size.

Typical locations for a seal like this include gearboxes, pumps, electric motors, rollers and other transmission assemblies where a shaft turns inside a lubricated housing. In plants you will find them on conveyors, mixers, mills and machine tools. They are also common on older machines, where matching the original size is the practical way to keep the housing untouched.

Selection comes down to three checks: shaft diameter, housing bore and height. It also pays to inspect the shaft surface where the lip will run; scratches or wear there will prevent a proper seal even with a new part. During installation, lubricate the lip and press the seal in evenly on its metal edge with a suitable tool. Do not strike the lip. Remove any burrs from the housing bore before fitting.

If the Lx design does not suit your application, tell us the equipment and the lubricant used, and we can point you toward the correct configuration.
