Spur gear made of polyketone die-cast with hub module 2.5 50 teeth tooth width 17mm outside diameter 130mm PN: 28705001

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.
