The DBH 9463 is a radial shaft seal, the kind of lip seal that sits in a housing bore and wipes against a turning shaft. Its job is twofold: hold lubricant inside the assembly and keep dust, water and particles out. The published dimensions are a 25.40 mm shaft, a 44.50 mm housing and a 7.92 mm height, with an Mx design. Gearboxes, pumps, motors and similar transmission equipment rely on seals like this one to shield bearings and gears from contamination. MR Industrial Accessories supplies the DBH brand and can confirm the size with you before you request a quote.

The code breaks down simply. DBH is the line, 9463 is the item reference, and the three numbers that matter for fit are the shaft, housing and height figures listed above. Mx refers to a single-lip profile built with a metal case and an elastomer element that rides on the rotating shaft. Because the section is shallow, this seal suits compact assemblies where there is little room for the sealing element but the lip still has to hold up over time.

You will find seals in this size range on equipment with rotating shafts: gearboxes, centrifugal pumps, electric motors, compressors, mixers and conveyors. In each case the lip keeps oil or grease from working its way out and stops external contamination from reaching the bearing or gear set. Some maintenance teams also fit one as a secondary barrier in a housing that already has a primary seal, adding protection against dust and splashes.

Installation decides how long the seal lasts. Inspect the shaft first: no burrs, no deep scratches, and a surface finish the lip can run against. The bore should be clean, round and free of dents, with the correct diameter. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in with a tube or socket that contacts only the outer edge, never the lip itself. For high-speed or pressurized service, ask about a reinforced profile or a different elastomer.

When you need a replacement, the fastest route is to send the code stamped on the old seal together with the shaft, housing and height measurements and a photo of the part. From that we can search the same DBH line or another brand we supply. If the shaft shows wear, we can also discuss a repair sleeve or a seal with an auxiliary lip before you commit to the repair.
