Hydraulic Cylinder DU Bushing is engineered to improve motion stability, reduce sliding resistance, and protect hydraulic cylinder components from premature wear. It is suitable for demanding cylinder assemblies requiring reliable guidance, long service life, and low-maintenance performance.
Hydraulic Cylinder DU Bushing is a self-lubricating sliding bearing designed for hydraulic cylinder applications. It supports smooth reciprocating movement, reduces friction between mating surfaces, and helps protect rods, pistons, and cylinder barrels from excessive wear during continuous operation.
The bushing structure combines a strong backing layer with a porous intermediate layer and a low-friction PTFE or polymer lining. This design allows reliable operation under heavy-duty working conditions while minimizing lubrication requirements and extending the service life of hydraulic equipment.
For hydraulic cylinders facing wear, friction, misalignment, or frequent maintenance issues, DU bushings provide an effective guiding and protection solution. They can be used as piston rod supports, wear rings, or guide elements to improve alignment, reduce side load impact, protect contact surfaces, and enhance cylinder reliability in harsh operating environments.
