Wear-resistant POM
For meshing or sliding wear and clearance growth, shortlist MoS₂-modified EMS102 and EMS162. Start with EMS102 for flow-sensitive molding and EMS162 when tensile strength leads selection.
Materials for moving parts
Motion Components
Continuous meshing calls for attention to tooth wear and heat; frequent starts and stops to stick-slip and impact. Compare lubricated, toughened or reinforced POM against the dominant risk, shortlist candidate grades and define molding-trial comparisons.

Typical components
Material requirements for moving parts
Transmission & actuation
For continuous meshing, control tooth heat and wear; for starts or reversals, balance root loading with impact toughness.
Precision Gear
Balance root fatigue and tooth wear. For continuous high speed, control heat and whine; for high-torque starts, prioritize root loading and impact.

Wear-resistant POM
For meshing or sliding wear and clearance growth, shortlist MoS₂-modified EMS102 and EMS162. Start with EMS102 for flow-sensitive molding and EMS162 when tensile strength leads selection.
View materials & gradesLow-friction POM
Include PTFE-lubricated EPTL402 in comparisons when low-speed starts, dry sliding or stick-slip noise are prominent. Record starting resistance, running torque and wear separately for steel–plastic and plastic–plastic pairs.
View materials & gradesRotary support
Bore wear widens radial clearance; eccentric load and heat accelerate failure. Compare starting torque and bore retention, then temperature rise under loaded rotation.
Roller
Bore wear increases radial runout; tread slip changes rolling resistance. Compare bore-clearance retention and tread wear separately alongside stiffness.

View materials & gradesLinear guidance
For frequent starts, address stick-slip noise; for long reciprocation, clearance growth. Compare starting force and wear by steel/plastic rail and dust exposure.
Guide Ring
Eccentric loading heats local contacts and accelerates one-sided wear. Prioritize friction and wear at the interface, then check guide clearance and uneven wear after reciprocation.
