10% carbon PTFE bushing manufacturer

As an established manufacturer specializing in engineered polymer bearings, we produce a broad range of self-lubricating components for demanding industrial applications. Our 10% carbon PTFE bushing for dry running is formulated to deliver reliable performance in environments where external lubrication is impractical, such as food processing equipment, textile machinery, and chemical pumps. The carbon filled PTFE sleeve bearing combines the inherent chemical resistance of PTFE with the mechanical strength of carbon reinforcement, resulting in a bearing that resists deformation under load and offers enhanced wear life. For applications demanding minimal breakaway friction in automation or precision instruments, our low friction carbon PTFE bushing is an ideal choice, while the PTFE bushing for high PV value is engineered to withstand elevated pressure-velocity conditions without compromising wear life in hydraulic cylinders, agricultural equipment, and conveyor systems. Each of these products is manufactured in-house under strict ISO 9001 quality controls, with full traceability of raw materials and dimensional inspection on every batch. We also offer customized sizing and machining to meet exact customer drawings, ensuring a drop-in replacement for existing metal or plastic bearings.

The 10% carbon PTFE bushing is produced through a controlled compression molding and sintering process that achieves uniform carbon dispersion and consistent mechanical properties throughout the wall thickness. Carbon reinforcement significantly improves thermal conductivity, dimensional stability, and wear resistance compared to virgin PTFE, making this bushing suitable for rotating, oscillating, and sliding movements under dry or marginally lubricated conditions. For engineers evaluating bearing materials, the 10% carbon PTFE bushing offers a unique balance of properties: the low friction of PTFE is retained, while carbon reinforcement increases load capacity by 25-40% compared to virgin PTFE and improves resistance to cold flow under static loads. This makes the bushing especially effective in applications with high side loads, frequent starts and stops, or low-speed high-load conditions.

Key product characteristics include:

• Self-lubricating operation with a dry friction coefficient between 0.05 and 0.10, eliminating the need for grease or oil
• Excellent chemical resistance across a wide pH range, including strong acids, alkalis, and most organic solvents
• Continuous service temperature from -200°C to +260°C, with short-term exposure tolerance up to +300°C
• Low moisture absorption (less than 0.01%) and superior dimensional stability under mechanical load
• Reduced stick-slip behavior and low breakaway torque for smooth motion control
• Available in standard and custom sizes to match shaft and housing requirements from 5 mm to 300 mm inner diameter
• Can be supplied as straight, flanged, or thrust washer configurations, as well as split designs for easy installation

Technical specifications for our standard 10% carbon PTFE bushing are summarized below:

We machine these bushings with tight tolerances to ensure precise fits and simplified assembly. Custom variations such as embedded metal casings, helical grooves for debris evacuation, or food-grade FDA-compliant versions are available upon request. Every batch is tested for dimensional accuracy, material hardness, and friction performance before shipment. Typical applications include linkage pins in construction equipment, valve stems in chemical processing, pump wear rings, and food-grade mixers. Because the material is non-corrosive and does not require lubrication, maintenance intervals can be extended and the risk of contamination is minimized. In wet or submerged environments, the bushing performs reliably without swelling or softening.
