The DBH 9109 is a radial shaft seal built to keep lubricant in and contaminants out on rotating shafts. It fits a 31 mm shaft, a 45 mm bore, and an 8 mm width, with an Lx design that uses a single lip and a metal case. This seal works across many industrial machines, and MR can help you confirm it matches your equipment.
This seal from DBH carries the part number 9109. The shaft diameter is 31 mm, the housing diameter is 45 mm, and the height is 8.00 mm. Its Lx construction means one sealing lip and a metal outer shell, which suits rotary shaft applications. These measurements allow it to drop into standard housings as a replacement for worn seals and keep the assembly sealed.
You will find this size in gearboxes, pumps, electric motors, and drive shafts, as well as in agricultural machinery, conveyors, and hydraulic systems. It holds oil or grease inside while shielding bearings from dust and moisture. Because it is compact, it fits tight spaces around 31 mm shafts.
Before installation, check that the shaft and bore match the listed dimensions. The shaft should be smooth and free of burrs. Lubricate the lip before pressing the seal in, and use a proper mounting tool to avoid damage. Consider shaft speed, temperature, and the fluid being sealed when selecting. If you are unsure, send us your details and we will help you verify the choice.
