The DBH 5521 is a radial shaft seal designed to keep oil or grease contained in equipment with rotating shafts. It is press-fitted into the housing, and its flexible lip runs against the shaft to block leaks and keep out dust or water. With a 35 mm shaft, 52.37 mm housing and 11.11 mm height, and the Mz design, it serves as a replacement in gearboxes, pumps and electric motors. MR Industrial Accessories supplies this seal as a brand.

This seal belongs to the DBH line and carries the code 5521. Its dimensions are shaft 35 mm, housing 52.37 mm and height 11.11 mm. The Mz design indicates a sealing lip with a metal case, built to retain lubricant and exclude contaminants in rotating service. It is a precision component that presses into the housing and needs a properly finished shaft surface for the lip to seal effectively.

Seals of these dimensions are commonly found in gearboxes, reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In each case, the seal keeps oil or grease inside the assembly and shields bearings and gears from particles. They also suit equipment exposed to splashes or dusty conditions, as long as the lip material is compatible with the fluid and the operating temperature.

When selecting and installing this seal, confirm that the shaft and housing match 35 mm and 52.37 mm. The housing must be clean, free of burrs and have a sound entry chamfer. Lubricate the lip before fitting and avoid impact during installation. The 11.11 mm height sets the axial space required. If the shaft is worn or rough, consider a repair sleeve or consult our technical team.
