The DBH 1299 is a radial shaft seal with a Kx-Bidi lip design, used to keep lubricant in and contaminants out where a rotating shaft passes through a fixed housing. Its dimensions are 108 mm for the shaft, 133.40 mm for the housing bore and 12.00 mm for the height. MR Industrial Accessories supplies this seal and can help you confirm the size before you request a quote.

This seal carries the code 1299 within the DBH series. The three dimensions to check are shaft 108 mm, housing 133.40 mm and height 12.00 mm. The Kx-Bidi designation refers to the lip geometry and its bidirectional layout, which means it can seal with lubricant on both sides or with rotation in either direction. It is not a load or speed rating; those figures come from the manufacturer's data sheet.

Seals of this size are common in gearboxes, conveyor rollers, centrifugal pumps, mixers and continuous process equipment. You will also find them on road construction and agricultural machinery, and in chain or belt drive lines where a 108 mm shaft runs inside a machined housing. The job is always the same: hold oil or grease in the assembly and keep dust, water and particles away from the bearings.

Before installation, confirm that the shaft and housing match the data sheet values. Inspect the shaft for burrs or wear on the sealing track, and make sure the housing is clean and free of impact damage. Press the seal in squarely using a press or a support tube on the outer edge; never strike the lip. Lubricate the lip with the same grease or oil used in the equipment before closing up. If the shaft has a deep groove, a wear sleeve may be the better option.

To request a quote for the 1299, send the shaft, housing and height dimensions you measured on the equipment. A photo of the old seal or the assembly drawing also works. With that information we can point you to an alternative in the same series or another brand we supply, and provide a quote. The code does not have to match exactly; the size is what counts.

MR Industrial Accessories handles seals and oil seals for replacement and maintenance work. If the 1299 is the seal your machine needs, message us on WhatsApp with the code and dimensions. We will reply with a quote and, when applicable, an equivalent option. We can also advise on installation if you tell us the equipment and how the shaft looks.
