What is a phenolic resin with cotton fiber guide ring？
Phenolic resin with cotton fiber guide rings are used for hydraulic cylinder piston or piston rod, support piston or piston rod movement parts. Guide rings can prevent the piston or piston rod in the process of movement and cylinder direct contact and friction, to protect the cylinder and the piston or piston rod is not damaged.
What are the effects caused by improper use or operation of guide rings?
1. Cavity, rough piston rod surface, scratch and wear the seals
2. Improper size is easy to lead to leakage or channeling of the cylinder.
Kintowe phenolic resin with cotton fiber guide ring is high-strength laminated material based upon the thermosetting phenolic resin and reinforced with high-quality cotton fiber and finally finished with heat solidifying process under certain pressure and temperature. This material is featured in its high load sustainability, excellent temperature resistance, abrasion resistance and excellent dimensional stability. It is applied to the production of guide rings of hydraulic cylinders, support rings, engineering machineries, bushings for the pivot axles for vehicles, thrust plates, guiding sleeves for the pillars of hydraulic machines, etc.
