The DBH 8678 is a radial shaft seal designed to retain lubricant and exclude contaminants where a rotating shaft passes through a housing. With a 25.00 mm shaft diameter, a 35.00 mm housing diameter and a 7.50 mm height, it fits compact power transmission and general machinery applications. MR Industrial Accessories supplies it as part of its seals and oil seals line.

This seal corresponds to the Mx design, which defines the lip geometry and metal body construction. The dimensions come from the 8678 designation: shaft 25.00 mm, housing 35.00 mm, height 7.50 mm. Before mounting, verify these three values against your shaft and housing to ensure a proper fit.

Radial shaft seals like the DBH 8678 are commonly found in gearboxes, pumps, electric motors, transmission shafts and process equipment. They serve two purposes: keeping oil or grease in and keeping dust, water or particles out. In dirty or wet environments, they work alongside other seals to protect bearings and gears from premature wear.

When selecting a radial shaft seal, consider shaft diameter, housing diameter and depth, rotation speed, working temperature and lubricant type. The Mx design influences how the lip performs against the fluid. During installation, orient the lip toward the lubricant side, ensure the shaft is clean and free of burrs, and use a tool that presses on the metal edge, never on the lip.
