Our plastic gears are used across multiple industries including:
Q: What are the main advantages of plastic gears over metal gears?
A: Plastic gears offer several benefits including lighter weight (up to 80% reduction), inherent lubrication properties, corrosion resistance, noise reduction (up to 50% quieter operation), and cost-effectiveness for medium-duty applications. They also eliminate electrical conductivity concerns and don't require additional surface treatments.
Q: How do I choose the right plastic material for my gear application?
A: Material selection depends on multiple factors: POM (acetal) offers excellent dimensional stability and low friction for precision applications; Nylon provides good impact resistance and fatigue life; PEEK is suited for high-temperature environments. We recommend consulting our engineers who will consider your load requirements, operating environment, temperature range, and chemical exposure to suggest the optimal material.
Q: What maintenance do plastic gears require?
A: Plastic gears typically require less maintenance than metal gears. They don't need lubrication in many applications, though some high-performance polymers may benefit from occasional grease application. Regular inspection for wear patterns or deformation is recommended, with typical service life ranging from 500,000 to over 5 million cycles depending on load conditions and material selection.
