POM Guide Rings
Product Details
Product Introduction
Pom guide rings in hydraulic cylinders the most commonly used guides are guide rings and guide strips. They accommodate radial loads of forces acting on the cylinder assembly and guide the rod in the cylinder head as well as the piston in the cylinder bore.Guides are made of polymer materials and prevent metal-to-metal contact between moving parts in a working hydraulic cylinder. Compared to metal guides, polymer guides provide the following advantages in hydraulic cylinders:
• Significantly longer service life
• Work more smoothly against the cylinder bore and the sealing surfaces
• Avoid wear of cylinder surfaces despite the presence of contamination particles
• High resistance to insufficient lubrication at low speeds
• Larger contact area due to higher degree of elastic deformation distributes the load and reduces stress to counter-surface
• Certain self-lubricating properties
POM is polyacetals and polyamides are among some of the technical plastics.As a result of their favourable properties-good dimensional stability,high level of hardness,stiffness and strength with good toughness and resistance to chemicals,as well as good sliding and abrasion behaviour,they help in pushing the application limits favourably in several cases.
Product Parameter
Temperature range ℃: | -45℃ ~ +100℃ |
Pressure resistance bar(RT): | dynamic 500 bar, static 750 bar |
Main application: | Guide rings,Backup rings,Seal housings |
Resistant to: | Several organic media such as alcohols,aldehydes,esters and glycols,petrol and mineral oils,diluted alkaline solutions.e.g.suds,diluted acids and good resistance to hydrolysis. With PA, you need to reckon with weight gain resulting from water absorption. |
Not resistant to: | Oxidising chemicals and concentrated acids,in case of homo-polymerisation,long-term use in water beyond 65℃ is not favourable.Damage caused by UV radiation,carbon-filled types are more resistant to UV radiation. |
Product Details
Pom guide rings are used as piston and rod guides due to their outstanding friction behavior, stick-slip free running and good resistance to high temperatures and chemicals.
Advantages
- No stick-slip effect when starting for smooth operation even at very low speeds
- Minimum static and dynamic friction coefficient for low operating temperature and energy loss
- Outstanding lubrication conditions further improved by the teardrop structure
- Suitable for non lubricating fluids depending on material for optimum design flexibility
- High wear resistance ensures long service life
- Installation grooves according to ISO 10766
- Suitable for most hydraulic fluids in relation with the majority of modern hardware materials and surface finish depending on material selected.
- Suitable for new environmentally-friendly hydraulic fluids
- The embedding of foreign particles is enhanced
- Good damping effect, absorbs vibrations
