A rotating shaft needs a dependable barrier to keep lubricant where it belongs and keep dust and water out. The DBH 5566 radial shaft seal fills that role, sized for a 101.60 mm shaft, a 126.95 mm housing bore and a 12.70 mm height, with the Mx lip design. MR Industrial Accessories LLC supplies this seal and can help you confirm it fits your assembly.

The designation 5566 identifies this seal in the DBH line. Reading the number alongside the dimensions is the fastest way to check a replacement: shaft 101.60 mm, housing 126.95 mm, width 12.70 mm. The Mx design uses a single lip with a spring, a common configuration for general rotating shaft service. Keeping the 5566 reference on hand makes cross-referencing against other brands straightforward.

You will find seals of this type in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In each case the job is the same: hold oil or grease inside the housing and block dust, water and particles from reaching bearings and gears. A worn lip lets contamination in and lubricant out, which shortens the life of the parts around it.

Before pressing a new seal into place, inspect the shaft surface for burrs, scratches or wear at the lip contact area. Clean the housing bore and confirm it is round and free of damage. Apply a compatible grease to the lip, then seat the seal squarely. When selecting a replacement, account for shaft speed, operating temperature and the fluid being retained. If any of those details are unclear, share your equipment data with us.
