Part number 9734 is a DBH radial shaft seal with a single sealing lip and a metal case, sized for a 63.50 mm shaft, an 85.55 mm housing bore and a 12.70 mm height. It presses into the housing and its lip rides against the rotating shaft, holding lubricant inside the bearing cavity while keeping dust, water and process particles out. Because the lip flexes, it tolerates slight misalignment. Treat it as a wear item and swap it out as soon as leakage appears.

The Mx design in the DBH line uses one sealing lip with a metal outer case, which is why it fits a plain cylindrical bore rather than a recessed or split housing. The code breaks down simply: 9734 is the reference number you would look up in a catalog or spare parts list, and the three figures that follow describe bore, shaft and width. Here those figures are shaft 63.50 mm, housing 85.55 mm, width 12.70 mm. This is a catalog item, not a made-to-order seal.

Typical homes for a seal this size are gearboxes, pumps, electric motors, line shafts and general process equipment. Two jobs happen at once: oil or grease stays where the bearing needs it, and outside contamination stays out. In food, chemical and water treatment settings that barrier is what keeps the lubricant clean and the bearing running. Maintenance crews also reach for this size when an older machine's original seal is no longer easy to source.

Selection comes down to three measurements taken from the old part: shaft diameter, housing bore and height. The shaft should sit within tolerance, with no burrs, nicks or a worn track where the lip runs; a scored surface shortens seal life. The bore needs to be clean and round. On assembly, coat the lip with the same oil or grease the equipment uses, seat the seal square to the shaft, and drive it in with a tube that contacts only the metal case. Keep the hammer away from the lip and its spring.

To get a quote for 9734, send the three dimensions of the seal you are replacing. From there we can match it in the same brand or in another brand of comparable quality, and we can also look at options such as a second lip or a different elastomer when the fluid or operating temperature calls for it. Complete information gets you a faster answer.

Send part number 9734 over WhatsApp or email, and include a photo of the old seal or the machine's ID plate if you have one. Our team replies promptly and can suggest equivalents or help you confirm the right choice, so a leaking seal does not turn into unplanned downtime.
