Part of the DBH seal range that MR supplies, the 8709Vit is a single-lip radial shaft seal built around a 45 mm shaft. It keeps lubricant where it belongs and blocks dust, water and other particles from reaching the bearings and bushings behind it. The seal presses into a 60 mm bore and measures 9 mm in height, which makes it a frequent replacement item on pumps, motors, gearboxes and other rotating equipment in workshops and plants.

Read the designation as an Lx-R-H seal: the lip rides on the shaft, the outer diameter holds the part in the bore, and the casing height completes the envelope. The numbers to match are shaft 45 mm, housing 60 mm, height 9.00 mm. The series letters tell you the construction and lip compound, which the manufacturer's product page confirms when you ask for a quote.

You will run into this size on centrifugal pumps, electric motors, reducers, transmission shafts and process equipment that runs continuously. In each case the seal is what keeps oil or grease around the bearings and bushings and keeps contaminants out. Agricultural machinery and pumping lines are two common places to find a 45 mm shaft with this seal.

Before ordering, compare the three measurements against the actual bore and shaft. Look at the shaft surface as well: a grooved or burred track will shorten lip life no matter how good the seal is. When fitting, coat the lip with the same lubricant used in service, seat the seal square to the shaft and press on the outer edge rather than striking the lip. A chamfered bore helps the seal enter without distortion.

If the exact size is not what you need, or you want an alternative, send the code 8709Vit or your own measurements over WhatsApp. MR can check the same series or another brand for a seal that does the job. A photo of the old part and the housing helps avoid mix-ups.

MR supplies DBH as part of its seals and oil seals line. If the equipment is still running, replacing a hardening lip early is cheaper than dealing with leakage that reaches bearings and shafts. Message us on WhatsApp with 8709Vit and we will quote the seal or a suitable equivalent.
