GUIDE RING

In hydraulic cylinders the most commonly used guides are guide rings and guide strips. They accommodate radial loads of forces acting 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 contamination       particles
• 4.high resistance to insufficient lubrication at low speeds
