The DBH 5690 is a radial lip seal built to hold lubricant in place and keep dust, water and other contaminants out of rotating assemblies. Its Mx design belongs to the DBH seal range, and its three working dimensions are a 34.93 mm shaft, a 63.55 mm housing bore and a 12.70 mm height. MR supplies this seal as one more item in its seals and radial shaft seal catalog for industrial maintenance work.

Reading the code is the quickest way to confirm you have the right part. The 5690 number identifies this seal, while the Mx designation tells you which construction variant inside the DBH line you are looking at. The three dimensions work together: the lip runs on the rotating shaft, the outer diameter seats in the housing cavity, and the height sets how much axial room the installation needs. All three have to line up with your equipment before you order.

Seals of this size turn up in gearboxes, pumps, electric motors, reducers and other power transmission equipment. The job is always the same: keep oil or grease where it belongs and stop particles, water or dust from getting in. Plants running continuous processes often replace them on a preventive schedule, before a leak shows up, and the same dimensions appear in agricultural and industrial machinery with shafts close to 35 mm.

Selection comes down to matching the shaft, the housing and the available depth. Check the shaft surface first: burrs, scratches or heavy wear will shorten lip life no matter how good the seal is. At installation, coat the lip with the same oil the equipment uses and drive the seal in with a tube that presses on the outer diameter, never on the lip. Keep it square to the housing and avoid impacts.

If you are not sure about compatibility, send the code 5690 along with your shaft, housing and height measurements. A photo of the old seal or the assembly drawing works too. With that information we can point you to a direct alternative in the same brand or in another line we carry, matching the same critical dimensions and a similar configuration.
