MR Industrial Accessories supplies this brand and helps you select the right seal for your application.

The 9878 designation identifies a radial shaft seal with these dimensions: shaft 72 mm, housing 93.30 mm, width 7.95 mm. The A 146 design refers to a specific construction within the DBH line. The sealing lip contacts the rotating shaft while the outer case presses into the housing. Before replacing, confirm that all three dimensions match your equipment.

Seals of this size are common in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. Their role is to contain lubricant and block dust, water and particles, which helps protect bearings and gears. As a wear part, it should be inspected at every preventive maintenance interval and replaced if you see leaks, hardening or lip wear.

Proper installation starts with cleaning the housing and shaft and checking for burrs or scratches. Lubricate the lip before inserting the seal. Press it in perpendicular, without hammer blows that could deform the case. If the shaft shows wear, an auxiliary lip design may be needed. Speed, temperature and lubricant type all affect selection; share those details and we can guide you to the right variant in the DBH line.
