Ant Spinner Pulley – 18T-3m-05

Description

A lightweight aluminium pulley designed for belt-driven weapons in antweight combat robots.

The 18-tooth pulley is compatible with HTD3M and S3M timing belts up to 5 mm wide. It mounts directly onto the 5 mm shaft of an outrunner motor using the motor’s prop nut, with two additional M3 set screws providing extra security.

At only around 3.5 g, it is a good option for compact weapon systems where keeping the drivetrain light is important.
