The DBH 5322Sil is a radial shaft seal sized for a 20 mm shaft, a 32 mm housing bore and an 8 mm width, built in the Lx design. Seals of this type keep lubricant where it belongs and keep dust, water and other contaminants out of rotating assemblies such as gearboxes, pumps, electric motors and power transmission equipment. The flexible lip rides against the shaft so the seal holds up through continuous rotation. We supply this brand within our seals and oil seals line and can help you match it to your equipment.

Reading the designation helps when you compare it against a worn part. DBH identifies the radial shaft seal family, 5322Sil is the reference, and the three figures describe the fit: shaft 20 mm, housing 32 mm, width 8 mm. The Lx design pairs a sealing lip with a metal case, so the seal presses into a cylindrical bore and stays put. A spring behind the lip keeps contact pressure even against the shaft, and the lip elastomer does the actual sealing work. It belongs to the standard radial shaft seal and oil seal category, which makes cross-referencing straightforward.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and similar power transmission assemblies. In every case the job is the same: hold oil or grease inside the housing and block dust, water and particles from getting in. Machine tools and agricultural equipment with shafts turning continuously are also common homes for it. Because the housing bore is only 32 mm, it fits into compact spaces where a larger seal will not go.

Before installing a replacement, confirm the shaft diameter sits within the recommended tolerance and that the running surface is fine and free of grooves or wear marks. The bore should be clean and free of burrs. Drive the seal in with a proper installation tool and keep the hammer away from the lip. Put a light film of lubricant on the lip first, and check that the spring faces the fluid side. If the shaft shows play or misalignment, a more flexible design may serve you better.

When you need a cross-reference, send the part number 5322Sil or simply your shaft and housing dimensions. Our team can propose alternatives from the same brand or from other brands we carry, keeping the dimensions and design type intact. If your installation space calls for a different height or a lip with special characteristics, we can point you in the right direction as well.
