China-based manufacturer | Export-focused B2B service | Fast turnaround
Why Self-Lubricating Plastics
Eliminate external lubrication, reduce maintenance, and enhance mechanical efficiency in demanding motion and sliding applications.
Lower Friction
Smoother motion without external oil or grease, reducing energy consumption and heat generation.
Reduced Maintenance
Cleaner operation with no contaminating lubricants, ideal for food, medical, and clean environments.
Extended Wear Life
Improved durability in sliding, oscillating, and reciprocating contact compared to unlubricated metals.
Seizure Resistance
Eliminates stick-slip and cold welding issues common in metal-on-metal contacts.
Noise Reduction
Inherent damping properties reduce operational noise and vibration in moving assemblies.
Application Versatility
Options for chemical resistance, high temperature, electrical insulation, and particulate-sensitive environments.
Common use cases: plain bearings, bushings, wear strips, valve seats, thrust washers, guide rails, gears, cams, rollers, and dry-running seals.
Materials We Machine
Leveraging a wide range of internally lubricated and tribological polymer grades to meet exacting performance requirements.
PTFE
Virgin & filled. Exceptional low friction, chemical resistance. Ideal for seats, seals, and low-load bearings.
UHMW-PE
Tough, impact-resistant, low-friction. Excellent for guides, wear strips, and conveyor components.
POM / Acetal
PTFE, silicone, oil-filled grades. Stable, machinable. Gears, bushings, precision sliders.
PEEK
Unfilled & tribological grades (PTFE, graphite, carbon fiber). High temp, high PV capability.
PPS
PTFE-filled. Dimensional stability, chemical resistance, dry-run tribology at elevated temperatures.
PAI / PI
Tribo-grades with PTFE/graphite. Exceptional high-temp wear and stiffness for demanding interfaces.
Nylon (PA)
PA6, PA66, PA12. MoS2 or oil-filled. Economical self-lubricating bushings, gears, guides.
PET / PBT
Engineering grades. Low wear, good dimensional stability for precision low-friction parts.

Design Guidelines for Self-Lubricating Parts
Optimize your component design for machinability, performance, and longevity in self-lubricating applications.
Fit Selection
Use clearance fits that account for thermal expansion and potential swell, especially for hygroscopic materials like nylon.
