The DBH 5685 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. Its dimensions are 31 mm shaft, 53.97 mm housing bore and 19.05 mm width. The Mr design refers to the lip and body configuration. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.

With a 31 mm shaft, 53.97 mm housing bore and 19.05 mm width, the 5685 designation tells you the three critical dimensions. The Mr design indicates a specific lip and body arrangement for rotating service. When replacing a seal, match all three dimensions; even a small difference can affect how the lip contacts the shaft and how the seal sits in the housing.

You will find this type of seal on pumps, electric motors, gear reducers, transmission boxes and other machinery with rotating shafts. It retains oil or grease and blocks dust, water and other particles. Automotive and agricultural equipment also use these seals where protection against contamination matters for bearings and gears.

Before installation, clean the shaft and housing and remove any burrs. Lubricate the seal lip, then check that the 19.05 mm width fits the housing depth. Selection depends on speed, temperature and the fluid being retained. If you are unsure, send the part number or your dimensions and the MR team can help you verify compatibility.
