A lip seal from the DBH line, the DBH 1232 keeps lubricant where it belongs and keeps dust, water and other particles out of the assembly. It fits a 100 mm shaft running inside a 135 mm housing bore, with a 12 mm height. Because the seal is pressed into the housing and its lip rides directly on the shaft, getting the size and the installation right is what decides how long it lasts.

Reading the designation is the quickest way to confirm the fit. The 1232 code covers three measurements: shaft, or d, at 100 mm; housing bore, or D, at 135 mm; and height, or h, at 12.00 mm. The Lx configuration means the seal has a sealing lip with a spring, which is the setup used when oil or grease has to be held back. DBH is one of the seal brands we supply, so the part number is enough for us to look it up for you.

These seals show up wherever a rotating shaft passes through a housing: gearboxes, pumps, electric motors, conveyor rollers and other power transmission equipment. You will also find them on agricultural machinery, linear guideways and hydraulic systems. In each case the seal is what separates the bearing from the surrounding environment, and the bearing is what benefits when the seal is sized and fitted correctly.

Before ordering, compare the three dimensions against the actual hardware. The shaft surface should be ground and free of burrs, and the housing should be clean with no deformation. Lubricate the lip before pressing the seal in, and use a tool that applies force to the outer ring rather than the lip. If the shaft itself is worn, an auxiliary lip or a wear sleeve is worth considering.

Have the full part number plus the shaft and housing dimensions ready when you contact us. We can walk you through what the DBH line offers or point you to another seal that does the same job. Details such as the lubricant, rotation speed and operating temperature help us give you a more precise recommendation.
