When a gearbox, pump or motor starts weeping oil around a rotating shaft, the DBH 5608 radial shaft seal is a standard replacement. It is a lip seal with a metal outer body that presses into the housing and a sealing lip that rides on the shaft. The size is given as 20 mm shaft, 33 mm housing and 10 mm height, which makes it easy to cross-check against the old part before ordering.

The code 5608 belongs to the DBH line of radial shaft seals. The Lr design means the seal has a sealing lip and a metal reinforcement, so it holds lubricant inside the housing and keeps dust and water out where the shaft turns. The three numbers you need to confirm are shaft diameter (d) 20 mm, housing bore (D) 33 mm and height (h) 10 mm. The same 5608 reference appears on the manufacturer's data sheet if you need to verify the exact replacement.

Seals of this size show up in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. Their job is to close the lubricant chamber and stop particles from getting in and wearing out bearings and gears. Because the lip is a wear item, it should be replaced as soon as a leak or steady drip appears.

Selection depends on shaft speed, operating temperature and the lubricant in use. Before installation, coat the lip with lubricant and make sure the shaft is clean and free of burrs or scratches that could cut the seal. Press the seal in evenly on the outer diameter, never hammering on the lip. If the housing bore is worn, a repair sleeve may be needed first.

If you are looking for an equivalent to the 5608, send the full code, the shaft and housing dimensions, the height and a photo of the old seal. With that information we can check for an alternative in the same DBH line or another brand we carry, and we can also help when the shaft or housing has special tolerances.
