When oil or grease has to stay inside a rotating assembly, the DBH 9231Vit radial shaft seal does that job between the shaft and its housing. Its measurements are 84 mm at the shaft, 104 mm at the housing bore and 11.00 mm in height, with an Lx-Hel design. Gearboxes, pumps and power transmission units are the usual places where this size turns up. MR Industrial Accessories supplies this brand and can check the dimensions with you before you ask for a quote.

Reading the code helps when you compare it against the old part. The 84 mm figure is the shaft diameter the lip runs on, 104 mm is the bore where the seal sits, and 11.00 mm is the height or width of the ring. The Lx-Hel designation tells you the seal carries a lip plus a helical spring, so contact on the shaft is maintained as it rotates. This arrangement suits shafts that turn under permanent lubrication, and it asks for a ground surface with no scoring, since a rough track shortens lip life.

You will find this size in gearboxes, centrifugal pumps, electric motors, rollers and other transmission equipment. The task is always the same: hold the lubricant in and keep dust, water and other contaminants out. Agricultural and general industrial machinery running at moderate speeds and normal working temperatures also use it.

Installation is straightforward if the bore is clean and free of burrs and the shaft shows no splines or wear at the contact zone. Put a little lubricant on the lip, then press the seal in square to the shaft so it does not twist or sit crooked. If the shaft already has a visible wear groove, moving the lip to a slightly different position is one option worth reviewing. Speed, temperature and the lubricant in use are the factors that settle the final choice.

For an equivalent, send the code 9231Vit together with the shaft, bore and height measurements, and a photo of the removed seal if you still have it. With that information we look at options in the DBH line or in other brands we carry and tell you which one fits without machining the housing. We can also check the Lx-Hel design against the manufacturer's data.

MR Industrial Accessories includes the DBH brand in its range of seals and oil seals. If the equipment is down or running, message us on WhatsApp with the code and dimensions and we will prepare the quote and help you decide between the same size and an alternative.
