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.
