The DBH 8396 is a radial shaft seal designed to retain lubricant and exclude contaminants in rotating equipment. With a 31.5 mm shaft diameter, 52 mm housing bore, and 8.50 mm width, it fits common gearbox and pump housings. Its Mx configuration—single lip with garter spring—suits lubricated shafts. MR supplies this seal and can help confirm the correct size for your application.
This seal carries designation 8396. The key dimensions are shaft 31.5 mm, housing 52 mm, width 8.50 mm. The Mx design means one sealing lip with a spring, intended for shafts running in oil or grease. The metal case and elastomeric lip work together to maintain contact under normal service conditions.
Typical uses include gearboxes, centrifugal pumps, electric motors, and conveyor rollers. The seal keeps oil or grease inside the assembly while blocking dust, water, and debris. It is a wear item; plan replacement when leakage appears or when the shaft shows grooving or roughness at the contact area.
Before installation, clean the housing bore and shaft, removing burrs and scratches. Apply a thin film of the equipment's lubricant to the seal lip. Press the seal in using a flat tool that contacts only the outer metal case—never the lip. The 8.50 mm width sets the axial space needed; do not force the seal into a shallower groove. If the shaft is worn, a repair sleeve may restore the sealing surface.
To request a quote, send the part number 8396 or the three dimensions along with a photo of the old seal via WhatsApp or email. MR can check equivalent options and advise on lip material and design based on the fluid and temperature.
For selection help, provide the shaft size, housing bore, and width from your equipment. The MR team will confirm whether the DBH 8396 fits or suggest an alternative with the same critical dimensions.
