Wear Rings and Strips
Update:2016-04-08
Wear rings and strips accommodate radial loads of forces acting on the cylinder assembly and guide the rod in the cylinder head as well as guide the piston in the cylinder bore.
Guides are generally made of a polymer material which avoids 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.
Work more smoothly against the cylinder tube and sealing surfaces
Avoid wear of cylinder surfaces despite the presence of contamination particles
High resistance to insufficient lubrication at low speeds
Provides larger contact area due to higher degree of elastic deformation which distributes the load more evenly and reduces stress to the counter surface
Provides certain self-lubricating ability
The most common materials for wear guides are listed below.
Glass fibre reinforced polymide (glass filled nylon)
Phenolic/fabric composites
PTFE (bronze filled)
