The DBH 9650 is a radial shaft seal used wherever a rotating shaft passes through a housing and lubricant has to stay inside. Gearboxes, pumps, motors and transmission equipment rely on this kind of lip seal to hold oil or grease in place and to keep dust and water out. Its three key measurements are 47 mm at the shaft, 80 mm at the housing and 13.80 mm in height, and those are the figures that decide whether it drops into your assembly.

Reading the designation is straightforward. The 47 x 80 x 13.80 mm size is what you compare against the old seal: shaft diameter, housing bore and overall height. When all three line up, the part goes in without machining or adapters. The lip runs against the rotating shaft while the outer diameter seats in the housing bore, usually a metal housing, closing the assembly.

This seal suits rotating-shaft equipment that has to retain lubricant: gearboxes, reducers, centrifugal pumps, electric motors, rollers and transmission machinery. It also fits units where outside contamination such as dust or wash water must be kept away from the bearing area. Selection comes down to shaft and housing dimensions plus the lip design, chosen according to the fluid and the rotation speed involved.

Installation calls for a few checks first. Look for burrs or wear on the shaft where the lip will contact, and confirm the housing is clean and not deformed. Put a little lubricant on the lip, then press the seal in squarely, without tilting or hammering one side. If the shaft already shows a groove, a seal with the lip set in a different position may be the better route. Speed, temperature and the lubricant in use all affect the final choice.
