Description
Material: Polyketone (PK), ivory-colored. Moulded version. Bores machined. Pressure angle 20º. Usable also under water or other mediums. Lower friction than polyacetal gears leads to much larger lifespan, even without lubrication. Much higher safety against tooth breaking, specially at longterm usage. Temperature Range: -40°C to +140°C due to the load.
