The DBH 9533 is a radial shaft seal sized for a 40 mm shaft, a 68 mm housing bore and a 7 mm width, built to the Lx design. It keeps oil or grease where it belongs and keeps dust, water and particles out of gearboxes, pumps, motors and similar rotating equipment. If you know the part number, requesting a quote is straightforward.

Reading the code helps you match the part quickly. The 9533 identifies this seal within the DBH line, and the three figures that usually accompany it describe the fit: shaft 40 mm, housing 68 mm, width 7 mm. The Lx designation points to a single lip with a spring, set up to hold lubricant in one direction of rotation. Together, those details describe a slim-profile seal whose lip rides on the shaft while its outer body stays seated in the housing bore.

You will find seals of this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives. The job is the same in each case: contain the lubricant inside the assembly and keep contaminants out, since grit and moisture speed up wear on bearings and gears. It also works as a secondary barrier on shafts turning at moderate speed with little pressure difference across the seal.

Installation calls for a clean shaft with no burrs or tool marks, and a contact surface with suitable roughness for the lip. Put a little lubricant on the lip before you press the seal in, and keep it square to the shaft rather than driving it in at an angle. When you pick a replacement, match shaft diameter, housing diameter, width and lip design, and also consider the fluid being sealed and the operating temperature.

To get a quote on code 9533, send the shaft and housing dimensions plus the width. It also helps to tell us the equipment it fits and the fluid it handles. With that information we can check for a compatible option in the DBH line or another brand we carry, and confirm tolerances and lip material against the manufacturer's data sheet.
