The DBH 8776 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Due to its compact dimensions, 13 mm shaft, 22 mm housing and 5 mm height, it is used in small equipment where axial space is limited and rotation speed is moderate. It is a wear part: when it starts to leak, it should be replaced before the lubricant escapes and damages the bearing.

The DBH 8776 is a seal with Lx design, with a sealing lip and metal body that fits by pressure into the housing. Its dimensions are 13 mm shaft diameter, 22 mm housing diameter and 5.00 mm height. The Lx design corresponds to a single-lip seal with spring, suitable for rotating shafts with grease or oil lubrication. The lip works on the shaft and the outer diameter maintains the fit in the housing. It is a common replacement part in power transmission equipment and light machinery.

It is found in small gearboxes, low-power electric motors, centrifugal pumps, compressors, fans and belt or chain drive equipment. It also appears in machine tools, packaging equipment, conveyor belts and compact hydraulic systems. In all those cases it performs the same function: retaining lubricant inside and preventing contaminants from entering from outside. When the seal fails, lubricant loss accelerates bearing wear and can cause an unscheduled stoppage.

To mount it, verify that the shaft is clean, free of burrs or marks, and that the sealing surface is not worn. The housing must be free of impacts and have the correct diameter. Lubricate the lip before inserting it and use a tube or press that bears on the outer diameter, never on the lip. If the shaft shows a groove from the old lip, you can evaluate a seal with an offset lip or a repair sleeve. The selection depends on speed, temperature and the type of lubricant; if you have doubts, ask us.
