Material: Polyacetal resin die-cast. Bores machined. Pressure
angle 20°. With high hardness and low friction coefficient these plastic
gears can be used in various set-ups, even under water. Note Regarding
the Machining Inside these die-cast parts are some cavities caused by
production. These parts should therefore not be drilled too deep. With
larger bores or when grooving the cavities might become visible. This
often does not affect the functionality.
