Phenolic fabric resin guide rings, as high-performance industrial seals, play an important role in modern industry. Their unique physical and chemical properties enable them to maintain stable performance in a variety of harsh environments.
You often use and purchase phenolic resin wear ring seals, but how much do you know about them? Let’s explore their more amazing features.
Performance Features
High-Temperature Resistance: They maintain stable performance in temperatures ranging from -60°C to 120°C, and even from -50°C to 150°C, making them suitable for high-temperature environments.
High Wear Resistance: Phenolic resin hydraulic cylinder guide rings offer high wear resistance, ensuring a long service life under high-speed operation and heavy loads. After tests show that they reduce wear by over 40% compared to ordinary nylon guide rings, ensuring a long service life even under harsh conditions such as heavy loads, high frequencies, and long travels.
High Corrosion Resistance: They offer strong corrosion resistance and excellent resistance to a variety of chemical media. They are not easily corroded by oils, acids, alkalis, and other substances and can adapt to complex chemical environments.
Strong Dimensional Stability: The preheating process during the thermoforming process eliminates volatile moisture and prevents shrinkage and deformation, thereby ensuring the dimensional accuracy of the guide ring and maintaining excellent guiding accuracy during operation.
High Compressive Strength: Phenolic resin hydraulic cylinder wear rings are typically reinforced with high-strength fiber fabrics (such as glass fiber and polyester fiber). The fiber network structure imparts high compressive strength and load-bearing capacity, capable of withstanding radial loads up to 50 N/mm², meeting the demands of heavy-duty operating conditions.
Low Friction Coefficient: Under dry friction conditions, the friction coefficient is only 0.08-0.12, and the fiber network structure effectively absorbs lubricant, achieving a near-self-lubricating effect. This low friction coefficient is maintained even in low- or no-lubrication conditions.
Vibration and Noise Reduction: With an elastic modulus between that of metal and pure plastic, it effectively absorbs mechanical vibration and impact, reducing piston rod vibration and preventing damage to seals caused by vibration, thereby improving system operation smoothness.
Impurity Absorption: Allows impurities to embed within the guide ring, preventing damage to the cylinder and seals, thereby protecting the seals from particulate matter.
Why Choose Phenolic Guide Rings?
When choosing a hydraulic guide ring material, you know the advantages of choosing phenolic guide rings are as follows:
Excellent Overall Performance: Combining high load-bearing capacity, wear resistance, high temperature resistance, chemical resistance, vibration damping, and low friction, they meet the needs of a variety of complex operating conditions.
Long Service Life: Maintains a long service life even under harsh operating conditions such as heavy loads, high temperatures, and vibration, reducing downtime, maintenance, and replacement costs.
Easy Installation: It has excellent machinability and can be machined into the required size and shape through processes such as turning, making installation relatively simple and quick.
High Cost-Effectiveness: Although its cost is relatively high, its excellent performance and long service life make it a highly cost-effective option in the long run.
In addition to the numerous advantages mentioned above, phenolic guide rings also have their disadvantages:
Unsuitable for high-speed operation: Although they have a low coefficient of friction, their performance is limited at high speeds exceeding 0.5m/s to 1 m/s, making their use inadvisable.
Difficult to process: Due to the high hardness and strength of the material, processing is relatively difficult, requiring high-quality equipment and processes.
High density: Their relatively high density may increase the weight of the equipment.
Phenolic resin piston & rod guide rings, due to their excellent overall performance, excel under complex operating conditions such as heavy loads, high temperatures, and vibration. They are essential components in hydraulic systems and other mechanical transmission equipment.
However, when selecting a phenolic resin, it is important to comprehensively consider its performance characteristics, advantages, and disadvantages based on the specific operating conditions to ensure that it meets the requirements of your equipment.
