The DBH 6743 is a radial shaft seal used to keep lubricant in and contaminants out of rotating equipment. It fits a 25 mm shaft, a 45 mm housing bore, and has a 10 mm height. The Lx design features a single sealing lip with a spring and no external dust lip, making it suitable for tight axial spaces.
This seal is identified by code 6743 and comes from the DBH line. Its dimensions are 25.00 mm shaft diameter (d), 45.00 mm housing diameter (D), and 10.00 mm height (h). The Lx configuration means a single lip with spring, without an outer dust lip. The elastomer lip and metal case work together to seal under continuous rotation.
You will find this seal in centrifugal pumps, electric motors, gear reducers, gearboxes, and transmission shafts. Its job is to seal the gap between shaft and housing, keeping oil or grease where it belongs and blocking dust, water, or particles. As a wear part, it should be replaced at each preventive maintenance interval or whenever a leak appears.
Before installing, check that the shaft surface is hard enough and finely finished, and that the housing bore is clean and free of burrs. Lubricate the lip with the same oil or grease used in service. Press the seal in with a tool that contacts the metal case only, never the lip. When selecting a replacement, consider peripheral speed, temperature, and the fluid being retained.
