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

Polyketone resin plastic bevel gears with ratios from 1:1 to 5:1 are high-performance components designed for efficient power transmission at a 90-degree shaft angle. These gears, typically die-cast from ivory-colored polyketone (PK), offer superior wear resistance, low friction, and a longer lifespan compared to traditional materials like polyacetal (POM) or nylon, even without lubrication. They operate effectively in temperatures from -40°C to +140°C and are suitable for use in wet environments due to low moisture absorption and excellent chemical resistance.

Description
Additional information

Available in modules ranging from 1 to 3, with machined bores from module 1.5, these gears are sold individually, requiring two matching gears of the same module and ratio for proper operation. For a 1:1 ratio, two gears with identical tooth counts are needed, while uneven ratios like 5:1 require gears with different tooth counts. Their high abrasion resistance and tribological properties make them ideal for precision mechanics and machine-building applications.
