When a shaft turns inside a housing, the DBH 1297 radial shaft seal keeps lubricant where it belongs and keeps dust and water out. It is a wear item: once it starts weeping oil or letting grit through, it has done its job and needs replacing. MR Industrial Accessories supplies this seal and can help you confirm the size before you order.

The three values that matter on this part are 133.40 mm for the shaft, 165.10 mm for the housing bore and 15.90 mm for the height, which sets how deep the seal sits in the bore. The Kx-R-H designation describes a lip configuration with a reinforced body built for tougher service. The code 1297 is simply the manufacturer's reference for this size, so do not read it as an inch measurement or as part of another series. If your equipment lists this reference, those three dimensions are what decide whether it fits.

You will find seals like this one in gearboxes, pumps, electric motors, rollers and other transmission equipment, as well as in agricultural machinery, industrial washers and conveying systems. The job is always the same: hold the lubricant in and block particles from getting in. Which lip compound and spring are used depends on the fluid in the machine and the temperature it runs at, so it pays to have those details ready when you ask about a replacement.

Before pressing a new seal in, check the shaft for burrs or grooves and make sure the bore is clean and free of dents. Put a film of lubricant on the lip, then seat the seal square to the shaft so the lip does not roll or distort. If the old seal died from heat or contamination, look at the bearing and the lubricant as well, since the seal is often the messenger rather than the cause. Shaft diameter, bore, height, fluid type and shaft speed are the inputs that confirm whether the Kx-R-H geometry is the right choice.

To get a quote on code 1297, send us that code together with your shaft and bore dimensions. A photo of the worn part or the assembly drawing works just as well. From there we can find an equivalent in the same brand or in another line that does the same job. You do not need to have the part number in hand; the dimensions and what the equipment does are enough for us to start the search.

MR Industrial Accessories supplies the DBH brand. Message us on WhatsApp with the code 1297 or with your measurements and we will prepare the quote. We can also look at whether a different lip profile or a different material would handle your fluid better. One inquiry should be all it takes to get the correct part.
