A radial shaft seal such as the DBH 9853Vit keeps lubricant where it belongs and keeps dust, water and particles out. It mounts on the shaft and closes against the housing, so the two diameters and the height are what decide whether it fits: 12.5 mm at the shaft, 22.5 mm at the housing and 5 mm of height. That small envelope puts it in compact assemblies, from miniature motors to light pumps and gear units. MR Industrial Accessories supplies the DBH seal line and helps you match the seal to the shaft, the housing and the working conditions.

Reading the designation is the fastest way to confirm the part. The DBH 9853Vit code sits inside the brand's radial seal range, and the three figures that follow describe the seat: shaft 12.5 mm, housing 22.5 mm, height 5.00 mm. Its Lx design is a single-lip seal built with a metal case and an elastomeric lip, made for rotating shafts that run with lubrication. Change the shaft diameter or the bore and the interference is lost, so these values are the ones to check on the drawing or with a caliper before the order goes out.

Where does a seal this size show up? Mostly in places with little room and moderate speeds: fractional-horsepower electric motors, small centrifugal pumps, worm gearboxes, light transmission housings, fans and machine tools. The job is always the same, holding oil or grease in and holding contaminants out, which is what protects the bearings and gears from accelerated wear. It also appears as a secondary barrier on control shafts and selector shafts.

Installation is straightforward but not forgiving. The shaft surface has to be clean, with no burrs or machining marks, and the lip should be lubricated before the seal slides on so it is not torn or rolled during assembly. Press it into the housing with a firm, even fit, without hammering that could distort the metal case. When you select the seal, weigh the rotation speed, the operating temperature and the fluid being retained, because a seal chosen for mineral oil is not the same as one for grease or for a wet environment. On a worn shaft, a seal with an auxiliary lip is worth considering.

For an equivalent, send the code 9853Vit together with the shaft and housing dimensions, a photo of the removed part and, when you have it, the equipment it came from. That is enough for us to identify the alternative in the same series or in another DBH seal line that drops in without re-machining. We can also tell you whether the housing will accept a different height or whether a design with dust protection suits the application better.

The DBH brand forms part of our seals and oil seals line. If the code is already in hand, message us on WhatsApp and we will quote the 9853Vit or the seal that matches your equipment. Describe the working conditions and we will help you settle on the right option.
