The DBH 9707 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It fits a 12 mm shaft, a 20 mm housing and a 4 mm height, and uses the Mt design. Because the sealing lip rides directly on the shaft, the seal wears over time and is replaced once oil starts escaping or dirt begins to enter.

This seal carries part number 9707 and the designation 12x20x4 mm. Its Mt design combines a metal outer case for press fitting with a flexible sealing lip. The small cross-section suits shafts of small diameter where there is little room along the axis but a dependable seal is still required.

Typical installations include gearboxes, pumps, electric motors, compressors and other power transmission equipment. The seal also appears in machine tools, agitators and lubrication systems. In each case it works in two directions at once: it holds oil or grease inside the housing and blocks dust, water and chips from reaching the bearing.

Before fitting a replacement, confirm that the shaft and housing are clean and free of burrs or scratches. Apply lubricant to the lip, then press the seal in with a tube that contacts only the outer diameter, never the lip. The shaft surface should be polished and free of splines. For equipment that runs with strong vibration or high temperature, verify the lip material and the service range on the manufacturer's product page.

To quote an equivalent, send part number 9707 together with the shaft, housing and height dimensions. It also helps to include the lubricant type, rotation speed and working temperature. With those details we review options in the DBH line or other brands we supply, always checking the technical data sheet before quoting.

MR Industrial Accessories supplies the DBH brand. If you already have the old seal on hand, send the stamped part number or the dimensions you measure with a caliper. We reply by WhatsApp with the matching reference and quote.
