The DBH 9177 is a radial shaft seal built to keep lubricant inside a housing and keep dust, water and other contaminants out. Its designation tells you the three dimensions you need: shaft 133.40 mm, housing 155.55 mm, width 14.00 mm. The Mx design refers to the lip and body configuration, which the manufacturer's data sheet describes in detail. MR supplies this brand, so you can source the seal by part number.

Reading the code is the fastest way to confirm a match. The 9177 identifies the item within the DBH line, and the three figures in the designation follow the usual order for this type of seal: d for the shaft, D for the housing bore and h for the width. Before ordering, measure the shaft and the bore of your equipment and compare them with those values. A seal that is even slightly off in any of the three will not seat or seal correctly.

You will find seals of this type in gearboxes, pumps, electric motors, conveyor rollers and power transmission machinery. Their job is to hold oil or grease at the rotating shaft and block the entry of dust, water and foreign particles that would otherwise reach the bearings and internal parts. Keeping that barrier intact is what protects the rest of the assembly.

The Mx designation points to a particular lip and body configuration. If your application runs at high speed, sees extreme temperatures or handles aggressive fluids, check the manufacturer's data sheet for the material and lip details of this version. Correct installation also matters: use the right tools, keep the lip free of nicks and seat the seal square in the bore.

If the dimensions you need are close to but not exactly these, send the measurements anyway. MR serves customers throughout the United States and in several Latin American countries, and the team can suggest equivalent options and help you choose. Just give the part number 9177 or your shaft, bore and width figures.
