Why do materials determine the level of appearance? You'll find out when you know what the guide ring is made of?
From the strict sense, guide ring is not belong to seal categories, because the guide ring doesn’t have the function of sealing, but in a broad sense, guide ring is a seal product, because the guide ring is one of the indispensable auxiliary seal in the combination sealing structure, which can be used to guide the piston and piston rod, to avoid the contact of metal surface.
Accustomed to the cold metal color of industrial parts, when you see the seal of macaron color, do you see the light at the moment? This is the guide ring.
To know that the color of the guide ring is not just because it looks good, the color of the guide ring represents the difference of its material.
In order to be more suitable for the working environment, there are many materials for the guide ring, such as phenolic resin composite materials, polyester resin composite materials, filled PTFE materials, POM materials etc., it can also be customized according to different working conditions.
Phenolic resin composite materials, reinforced with cotton fabric
Advantages:
Good mechanical strength, good dimensional stability, good chemical resistance, standard materials for hydraulic cylinders and wear rings.
Operating temperature: -40℃ ~ 130℃
Polyester resin composite materials
Advantages:
Good stability, low water absorption, high wear resistance, good self lubrication.
Application: Shipping, chemical plants, railways, agriculture, hydraulics, water/sewage treatment.
Filled PTFE materials
Advantages:
Good chemical stability, good heat and cold resistance, apply to oil, water, steam, chemicals and other medias; High mechanical strength, high pressure resistance, good wear resistance; Low friction coefficient, good self-lubrication.
Application: metallurgy, petrochemical, construction machinery, light industry machinery and other fields.
POM materials
Features: low cost, medium load bearing capacity, easy to install.
Operating temperature: -30℃ ~ 125℃
Application areas:
Commonly used in heavy equipment, agricultural machineries, trucks and cranes.
