50WR phenolic resin wear ring
Guide ring, also known as support ring, is a part used on the piston or piston rod of hydraulic cylinder or cylinder to support the movement of piston or piston rod. It can prevent direct contact and friction between piston or piston rod and cylinder block during movement, and protect cylinder block and piston or piston rod from damage.
Phenolic guide ring is a new type of green environmental protection material. It is made of thermosetting linear phenolic resin as the base material, high-quality cotton fiber or other fibers and their fabrics as the reinforcing material, and an appropriate amount of wear-resistant and antifriction additives.
Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.
It has high mechanical properties, good oil resistance, low water absorption and high wear resistance. For the piston and piston rod running in the hydraulic cylinder, the guide ring has a precise guiding effect and can absorb the radial force generated at any time. At the same time, the guide ring can prevent the metal contact of the sliding parts in the hydraulic cylinder. Compared with metal guide rings, non-metal guide rings have many advantages.
 |
Advantages: 1. Good wear resistance and long life; 2. Avoid contact between metals; 3. Low compression deformation; 4. Vibration absorbing; 5. Minimal water absorption; 6. The groove is simple and easy to install; 7. Low maintenance cost. |

Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.
The function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.
A glass filled nylon wear ring, also called wear band, offers high bearing load capacity over a broad range of temperatures.
SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.
The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.
Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.
JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be PEEK, modified PTFE.
