Cylinder – BR58010-FS005

Hydraulic pressure becomes linear force in this cylinder, the actuator that converts pump flow into the straight-line push or pull that lifts, tilts, or moves a load on the equipment it serves. A cylinder works by driving a piston and rod through a sealed bore under fluid pressure, and it is replaced or rebuilt when the seals leak, the rod scores, or the bore wears enough to lose holding pressure. Cataloged under hydraulics, it delivers the mechanical work the hydraulic circuit is built to produce.

Leak-down, drift, and slow or weak actuation are the signs a cylinder has worn past service, since a cylinder that cannot hold pressure cannot hold a load. Match the bore, stroke, and port and mount fittings to the cylinder being replaced, since those dimensions govern whether it fits the circuit and produces the correct travel.
