Polyketone Resin Plastic Bevel Gears Ratio 1:1 – 5:1

Polyketone resin plastic bevel gears with ratios from 1:1 to 5:1 are precision-engineered components designed for transmitting motion at a 90-degree shaft angle. Made from aliphatic polyketone (PK), a high-performance thermoplastic, these gears offer superior wear resistance, low friction, and excellent dimensional stability due to low moisture absorption compared to polyamide (nylon) or polyacetal (POM). They are injection-molded with straight teeth, typically featuring an engagement angle of 20°, and are available in modules ranging from 0.5 to 3.
