Wear Resistant PTFE Guide Ring for Hydraulic Shock Absorbers

This wear-resistant PTFE guide ring is precision-engineered for hydraulic shock absorber rod guide assemblies. Manufactured from filled or virgin PTFE resin, it delivers low-friction guidance, exceptional chemical resistance, and stable mechanical performance across an extreme temperature range of -180 degree C to +260 degree C. Produced with German DMG CNC machining centers under IATF16949:2016 quality management, every guide ring ensures consistent dimensional accuracy and long service life for automotive, truck, and heavy-duty applications.

Our PTFE guide ring is available as a gasket, washer, flat gasket, or custom profile to match your rod guide assembly requirements. Key properties include:

• Made of filled or virgin PTFE resin for maximum material flexibility
• Strong anti-chemical properties for long-term fluid compatibility
• Stable operation under extreme temperatures from -180 degree C to +260 degree C
• Consistent apparent density of 2.10 - 2.30 g/cm3 for reliable performance
• Tensile strength exceeding 15.0 MPa for structural integrity under load
• Ultimate elongation above 150% for installation flexibility without cracking
• Excellent non-sticky surface for easy maintenance and contaminant removal
• Good mechanical properties with no distortion and low friction coefficient

Q: What is the difference between filled PTFE and virgin PTFE?

Virgin PTFE is pure polytetrafluoroethylene offering the lowest friction and best chemical resistance. Filled PTFE incorporates additives such as glass fiber, carbon, bronze, or graphite to enhance specific properties like wear resistance, compressive strength, or thermal conductivity. Our engineering team can recommend the optimal grade based on your operating conditions.

Q: Can you produce guide rings to my exact dimensions?

Yes. We specialize in OEM production based on customer drawings or samples. With our German DMG CNC machining centers and in-house mold making workshop, we can achieve precise custom dimensions. If you do not have drawings, we can design according to your application requirements.

Q: What is the minimum order quantity?

Our standard MOQ is 1,000 pcs per order. For new sample development and trial runs, smaller quantities can be arranged upon discussion.

Q: How long does mold making and sample delivery take?

New mold development typically takes 7 days, with sample delivery in approximately 10 working days. For orders using existing molds, we can leverage our extensive mold library to save mold costs and reduce lead time significantly.

Q: What quality certifications do you hold?

We are IATF16949:2016 certified for automotive quality management. Our products have passed all relevant industry certifications and are widely approved and adopted by both domestic and international enterprises.

Q: What temperature range can this guide ring withstand?

Our PTFE guide rings operate stably from -180 degree C to +260 degree C, making them suitable for virtually all automotive and industrial hydraulic applications. For applications exceeding this range, please contact us to discuss alternative material options.

Q: Do you have existing molds that can save us tooling costs?

Yes. After many years of continuous production, we have accumulated a very large inventory of existing molds. If your required dimensions match an existing mold, we can eliminate or significantly reduce the mold cost for your order.
