Material: Polyacetal resin die-cast.

Moulded version. 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.
