For rotating shafts that need reliable oil or grease retention, the DBH 8221 radial shaft seal is a direct-fit option. It keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching bearings and gears. The seal fits a 51 mm shaft, a 63 mm housing bore and has a 6 mm height, and it uses the Ms design. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.
The DBH 8221 carries part number 8221 and is built to the Ms configuration: one sealing lip with a metal outer case. In practical terms, that makes it suitable for lubricated rotating shafts. Its three key measurements are shaft diameter 51 mm, housing diameter 63 mm and height 6.00 mm. Those figures match common housing sizes, so a worn seal can be swapped out without machining or adapting the machine.
You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. In each case it holds oil or grease in and keeps contamination out, which protects bearings and gears. Because it is a wear part, check it during scheduled maintenance. Hardening, cuts or a lip that has lost its elasticity are signs that replacement is due.
Correct installation extends seal life. Inspect the shaft first: it should have the right hardness and surface finish, with no burrs or marks that could score the lip. Apply the same oil or grease used in the application to the lip before fitting. Press the seal in squarely to the shaft, using a tube that contacts the outer diameter only, never the lip. If the housing bore is worn, look at a taller seal or a repair sleeve as an alternative.
When you need a cross-reference, send the part number 8221 or the three dimensions of the seal you are replacing. Adding the equipment brand and model helps us identify a compatible option. MR Industrial Accessories works with multiple brands and can advise on the best match for your application.
