Wear rings & guide rings in hydraulic cylinders are designed to support and guide the piston and piston rod in a hydraulic cylinder. They absorb transverse loads and prevent contact friction between metal parts in the cylinder, thus protecting the seals in the system. Hydraulic wear rings are mainly applied to the piston and piston rod.

WR wear ring is nonmetallic guiding and positioning element. Excellent compression resistance and wear resistance, high load performance and still flexible before it reaches its brittleness temperature. Also easy in installation.
RYT is ptfe bearing strip which has a strong load-bearing capacity. It must be installed for oil cylinders with large partial loads, such as various heavy-duty oil cylinders, high-pressure oil cylinders, and large oil cylinders.
KZT is PTFE Wear Rings used for moving piston and rod in cylinder. With good guide effect, it can absorb radial force anytime, prevent metal-to-metal contact in the cylinder, and reduce the friction.
One of TYS’s branches specializes in manufacturing wear ring seals in different materials, including phenolic resin wear rings, PTFE wear rings, nylon wear rings, POM wear rings, and other materials for piston guide rings. TYS piston wear rings and rod wear rings are non-metallic guide elements with excellent compression and wear resistance, high load-bearing capacity, simple design, and easy installation. TYS keeps many different types of standard metric hydraulic wear rings in stock.
TYS PTFE guide strips can prevent scratches or eccentricity and improve the seal’s durability. The low friction of PTFE material can eliminate creeping. The bronze-filled PTFE wear ring can be cut according to your size.
Although guide rings do not perform a sealing function, they are essential for supporting side loads and maintaining proper alignment inside hydraulic cylinders.
To see how guide rings work together with sealing elements, you may refer to our full hydraulic seals portfolio, where guide rings and sealing components are used as an integrated system.
