The Hydraulic Grapple Cylinder Piston is used to separate the pressure zones inside the cylinder which helps to extend and retract the grapple units of the machine. The piston is machined with grooves to fit elastomeric or metal seals and bearing elements. The difference in pressure between the two sides of the piston causes the cylinder to extend and retract. The piston is attached to the piston rod using threads, bolts, or nuts to transfer the linear motion. Attributes:• Resistance to breakage and deformation under the application of high compression forces in the cylinder• Designed to withstand high and repeated working loads• Resistance to change in properties when used in working temperaturesApplications:This Hydraulic Grapple Cylinder Piston is used to extend and retract the required cylinder for operating and controlling the attached grapple work tool attached to the machine.
