Guide Rings

Guide rings and guide strips In hydraulic cylinders the most commonly used guides
are guide rings and guide strips. They accommodate radial loads of forces acng on
the cylinder assembly and guide the rod in the cylinder head as well as the piston
in the cylinder bore. Guides are made of polymer materials and prevent
metal-to-metal contact between moving parts in a working hydraulic cylinder.
Compared to metal guides, polymer guides provide the following advantages in
hydraulic cylinders: 1) Significantly longer service life 2) Work more smoothly against
the cylinder bore and the sealing surfaces 3) Avoid wear of cylinder surfaces despite
the presence of contaminaon parcles 4) High resistance to insufficient lubricaon
at low speeds 5) Larger contact area due to higher degree of elasc deformaon distributes the load and
reduces stress to counter-surface 6) Certain self-lubricang properes
