The DBH 9423 is a radial shaft seal built to close off the point where a rotating shaft leaves its housing, keeping lubricant inside and dirt outside. Its 50 mm shaft, 68 mm housing and 8 mm width make it a common fit for gearboxes, pumps, motors and transmission units. Our team can help you confirm the size before you order.

Reading the code: 9423 points to one specific size, and the three figures that matter are shaft 50 mm, housing 68 mm, width 8 mm. The Lx designation describes a metal-cased seal with an elastomer lip, a layout meant for retaining grease or oil on a turning shaft. The case holds the seal firmly in the bore, while the lip does the sealing work against the shaft surface. Because the shaft turns continuously in most of these assemblies, the condition of that lip is what decides how well the seal performs.

Where it fits: speed reducers, centrifugal pumps, electric motors, transmission shafts and rollers are the usual homes for this size. In each case the seal keeps particles away from the bearings and gears behind it. Plants in food processing, chemical and general process work also use it when the lip compound suits the fluid being held back. Any 50 mm shaft that needs radial sealing is a candidate.

Installing it: the shaft surface should be smooth, free of burrs and hard enough to resist wear from the lip. Clean the bore and match it to the tolerance set for the 68 mm outside diameter. Put a film of lubricant on the lip before you slide it on, and check that the 8 mm width sits correctly in the housing depth. On high-speed equipment, weigh the elastomer choice against the temperature the seal will see. Our technical team can review the selection if anything is unclear.

Looking for an equivalent: pass along the full part number, or simply measure your old seal and give us the shaft, housing and width figures. From there we can search our seal line for other brands or lip configurations. If the mounting space allows, there may be room for a different height or lip style. The 9423 number locks in this particular size, but nearby options exist.
