The DBH 6703 is a radial shaft seal built to sit on a rotating shaft and close off the housing around it, holding lubricant in and keeping dust, water and other particles out. It carries the Lx designation, which points to a single lip with a spring, and its size is given as 30 mm shaft, 52 mm housing and 7 mm height. MR Industrial Accessories offers it within its seals and oil seals range.

Reading the code and the numbers is the fastest way to confirm a match. The 6703 identifies the seal, while the three figures describe where it fits: shaft 30.00 mm, housing 52.00 mm, height 7.00 mm. A metal case gives the seal its structure and the lip does the sealing. Because the Lx design uses one lip with a spring, it suits rotating shafts that run with oil or grease. In service it keeps the lubricant where it belongs and stops outside matter from reaching bearings or bushings.

You will find this seal in gearboxes, centrifugal pumps, electric motors, fans, mixers and power transmission assemblies, as well as in agricultural machinery, conveyors and process equipment with continuous shaft rotation. The job is the same in every case: hold the lubricant film at the bearing and shield it from contamination.

Before installing a replacement, compare the shaft diameter, housing diameter and height against the dimensions of the part you are removing. The shaft should be clean and free of burrs or marks, and the housing should not be deformed. Lubricating the lip first helps it seat, and a press tool that pushes the seal in squarely, without direct hammer blows, keeps it from going in crooked. A tilted seal or a scored shaft will cut its service life.

If you are looking for an equivalent, send the complete seal part number along with the shaft, housing and height dimensions, plus a photo or sample of the part. With that information we can search the DBH line or other brands we carry, and we can also tell you whether the Lx design is the right choice for your equipment.
