The DBH 9357 radial shaft seal is a lip seal that is fitted into the housing and closes against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 22 mm shaft, 50 mm housing and 8 mm height, and Lx design, it is a common size in gearboxes, pumps and transmission equipment.

This item is a radial shaft seal from the DBH line, identified with the part number 9357. Its dimensions are 22.00 mm shaft diameter, 50.00 mm housing diameter and 8.00 mm height, with an Lx design. The Lx design corresponds to a single-lip seal with a spring, intended for rotating shafts with lubrication. The flexible lip runs on the shaft and the outer metal case is fitted by interference in the housing. It is a wear part: over time the lip hardens or wears and starts to leak.

Typical applications for a seal of this size appear in gearboxes, gearmotors, centrifugal pumps, mixers, industrial washing machines and belt- or chain-driven transmission equipment. It is also used on fan, compressor and machine tool shafts where the oil must be separated from the environment. In all those cases it performs two functions at the same time: it prevents the lubricant from escaping and stops the ingress of contaminants that accelerate the wear of bearings and gears.

To install it properly, check that the shaft is within tolerance and free of burrs, and that the housing has the correct diameter and depth. Lubricate the lip before inserting it and use a tube or press that bears on the metal edge, never on the lip. If the shaft shows a worn track, consider fitting the seal with the lip in a slightly shifted position or replacing the shaft. The selection depends on speed, temperature and the type of lubricant; therefore it is advisable to confirm the Lx design against the manufacturer's data sheet.
