A radial shaft seal in the DBH line, the 9712 keeps oil or grease inside the assembly and keeps dust and water out where a shaft turns within a housing. The Ms variant is a single lip with a spring, intended for lubricated rotating shafts. It turns up in gearboxes, pumps, motors and transmission equipment. MR Industrial Accessories supplies this brand and quotes it by part number.

Reading the code is straightforward: the part number is 9712 and the size is given in the order shaft, housing, height. For this seal that means a shaft of 14.2 mm, a housing bore of 28.55 mm and a height of 13.50 mm. The sealing lip rides on the shaft surface while the outer body presses into the bore, so the fit holds by interference. The spring behind the lip keeps it in contact as the shaft turns.

Typical service is any place a rotating shaft passes through a casing: gearboxes, centrifugal pumps, electric motors, compressors, mixers and machine tools. Power transmission drives use it as well, along with agricultural and road equipment where lubricant has to stay in and bearings have to stay protected. Treat it as a wear part. Once the lip hardens or picks up marks, leakage starts and the seal is due for replacement.

When fitting one, look over the shaft first for burrs, scratches or a worn contact band, and make sure the bore is clean and undamaged. Coat the lip with the same oil or grease the equipment runs before you slide it on. Use a tube or a press and apply force evenly on the metal body, never on the lip. If the shaft already has a deep groove, consider a seal that positions the lip on a different track.

Looking for the same seal from another maker, or an equivalent? Send part number 9712 along with the shaft, housing and height figures and we will check options in the DBH line and in the other brands we carry. Without those measurements, the equipment model or the reference printed on the old seal is enough for us to cross it. Our team also helps with selection when you are unsure which variant fits.

MR Industrial Accessories includes the DBH brand in its seals and oil seals range. To get a quote on the 9712, message us on WhatsApp or by email with the part number and dimensions. We answer promptly and can suggest equivalents and help you pick the right seal.
