A lip seal such as the DBH 8617Pol works as the barrier between the rotating shaft and the housing: it keeps lubricant inside the assembly and keeps dust, water and other contaminants out. The Lx-H-AH profile pairs a sealing lip with a reinforced body, which suits equipment that runs continuously and sees dirty conditions. Gearboxes, pumps, electric motors and transmissions that support their shafts on bearings or bushings are the usual places where this type of seal is found.

Reading the size is straightforward: shaft 105 mm, housing 142 mm, height 13.00 mm. The Lx-H-AH designation describes how the lip and the body are shaped, with a reinforced section that presses into the housing while the lip rides on the shaft. MR supplies the DBH line, and the part number is ordered just as it appears here. Check the shaft and the bore against these figures, and confirm that their surface finish matches what the seal needs, before you install anything.

Seals in this size range turn up on medium-section shafts: gear units, centrifugal pumps, electric motors, mixers, conveyors and machine tools. Another common job is closing off a ball or roller bearing set in a split housing, where the seal stops grease from working its way out and grit from reaching the raceway. On equipment that vibrates heavily or runs hot, inspect the shaft surface first; a worn or grooved shaft will shorten the life of any new seal.

Choosing a radial shaft seal takes more than the three dimensions. Speed of rotation, working temperature, the lubricant in use and any pressure difference across the seal all shape the decision. The Lx-H-AH profile is often picked where external dirt is present and a lip with good wear resistance is wanted. When mounting, coat the lip with lubricant, seat it square to the shaft and avoid hitting it with a hammer. A damaged bore or a grooved shaft can take a fresh seal out of service within hours.

For an equivalent, send the complete part number 8617Pol along with the shaft, housing and height measurements. With those details we can look through the DBH range or check a compatible option. We can also tell you whether a different lip design or an auxiliary lip will work in your housing. The more you can share about the equipment, the quicker we get to the right part.

Send part number 8617Pol to MR by WhatsApp or email and we will prepare your quote. If the size or the design is unclear, include a photo of the old seal next to the shaft and housing dimensions. Our team handles the seals used across industry every day and will help you settle on the replacement.
