The guide ring mainly plays a guiding role, and is mainly suitable for guiding the piston and piston ring in the hydraulic cylinder, and plays a supporting and guiding role.
Guidance series products are：Guide ring, guide sleeve, support ring, stop ring, L-shaped stop ring, phenolic cloth guide ring, gasket, guide belt.
The guide ring, also known as the support ring, is a piston or piston rod hydraulic cylinder or cylinder used to support the piston or piston rod moving parts, it can prevent the cylinder body from direct contact and friction during the movement of the piston or piston rod, and protect the cylinder body and the piston or piston rod are not damaged. Commonly used materials for guide rings are polyoxymethylene (POM) or PTFE (PTFE+bronze, PTFE+carbon, PTFE+graphite, etc.).
The hydraulic cylinder support guide ring is generally made of engineering plastics with good self-lubricating and anti-wear properties such as PTFE, polyoxymethylene, polyamide (nylon PA). The use of support guide rings has the following advantages:
(1) No cylinder is pulled out, and the leakage is small. The outer surface of the support ring is completely separated from the inner wall of the piston cylinder. No matter how serious the "tension" phenomenon is, there will be no "cylinder pulling" phenomenon. Due to the high coaxiality of the friction pair and the more uniform radial clearance, the leakage is reduced Small.
(2) Polish and thin the inner wall of the cylinder to protect the seal. The support ring on the piston slides back and forth relative to the inner wall of the cylinder, which is equivalent to polishing the inner wall of the cylinder with a soft substrate. Therefore, the lower the surface roughness, the better. Tiny polished metal powders are embedded in the soft surface of the ring to protect the seal.
(3) Good bearing capacity and easy replacement. The PTFE bearing ring is resistant to (25 ~ 30) MPa, and the reinforced glass fiber synthetic resin is resistant to (270 ~ 350) MPa. The guide ring is open type (floating type), easy to replace after wear and tear
