The DBH 9117 is a radial shaft seal that sits in the housing bore and rides against the turning shaft. It keeps lubricant where it belongs and keeps dust, water and debris out. Its designation gives the three values you need to match: shaft 26.00 mm, housing 47.00 mm, height 6.30 mm. The Lx design is a single lip with a spring. Gearboxes, pumps, motors and power transmission equipment are the usual homes for a seal this size. MR Industrial Accessories LLC supplies it as a brand.

Reading the code is the fastest way to check a replacement. The 26.00 mm figure is the shaft the lip contacts, 47.00 mm is the bore it presses into, and 6.30 mm is how tall the seal stands. The Lx design means one elastomeric lip backed by a spring: the lip wipes the shaft, the spring holds steady pressure on it, and the metal outer case grips the housing. Because the lip works against a moving surface, it is a wear part. Heat, grit and time harden or score it, and that is when you see a weep turn into a drip.

Seals of this size turn up in reducers, centrifugal pumps, electric motors, compressors and belt or chain drives, and also in machine tools, agitators and conveyors. Whatever the machine, the job is the same: keep the oiled side separate from the outside. Where dust, chips or washdown water are present, the seal is the first line of defense, so add it to the route during every maintenance interval rather than waiting for a leak.

Installation goes better with a few habits. The shaft surface should be clean and free of burrs, nicks or a worn groove where the lip rides, and the bore should be smooth with no dents. Coat the lip with the same oil or grease the equipment runs before you seat it. Drive it in with a tube or spacer that presses on the outer edge, never with a direct hammer blow. If the shaft already shows a groove, a seal that positions the lip elsewhere may be the better answer. Speed, temperature and the lubricant in use all feed into the final choice.

For an equivalent, send the code 9117 together with the shaft, bore and height measurements and the fluid involved. A photo of the removed part or the drawing helps too. With that information we check options in the DBH line and in other brands we carry, and where there is room we can look at a different height or a design that fits the application more closely. Quotes go through WhatsApp or email by part number, and our team answers promptly, confirms the size and suggests equivalents when needed.
