PEEK Gears & Bearings
Polyetheretherketone (PEEK) is a premier choice for manufacturing high-performance gears and bearings that must endure demanding mechanical, thermal, and chemical conditions. At Canyon Components, we offer both standard and custom-engineered PEEK gears and bushings designed for critical applications in aerospace, medical, semiconductor, and industrial machinery. PEEK's ability to maintain dimensional integrity, resist wear, and perform under thermal and chemical stress makes it an ideal replacement for metal and lower-grade plastics in precision motion and support components.

PEEK Material Advantages
PEEK offers a unique combination of tribological and mechanical benefits:
- Low Coefficient of Friction: Naturally slick surface minimizes wear and heat generation.
- High PV (Pressure-Velocity) Limits: Sustains high rotational speeds under load.
- Self-Lubricating Grades: Filled versions with PTFE, graphite, or carbon fiber reduce the need for external lubricants.
- Excellent Dimensional Stability: Minimal creep under load and low thermal expansion ensure tight tolerances.
- Thermal and Chemical Resistance: Operates in continuous service temperatures up to 260°C (500°F) and withstands aggressive chemicals, steam, and cleaning agents.
Machined vs. Molded Gears and Bearings
Canyon Components supports both precision machining and injection molding of PEEK gears and bushings:
- Machined PEEK Parts: Ideal for low to mid-volume production, prototypes, and applications requiring ultra-tight tolerances or complex geometries. CNC machining allows for quick turnaround and design flexibility.
- Molded PEEK Parts: Best for high-volume production, molded components reduce per-part cost and can include integrated design features like self-centering hubs or lubrication grooves.
Our team can advise on the most cost-effective and performance-appropriate method for your specific project.
Please consult a Canyon Components Engineer about your specific application and we will use our decades of experience to formulate a solution that fits your need.
