OVJ Plastic Pulley 25mm

The OVJ Plastic Pulley is a small, circular pulley made of white plastic, designed for use in mechanical systems and educational kits.

Each pulley features a deep groove around its circumference, ideal for guiding a belt or string, and a central hole for mounting on an axle or shaft.

Identical in design, they are commonly used to redirect force, transmit motion, or lift objects in DIY projects, robotics, and small-scale machinery.

Their lightweight yet durable construction makes them suitable for classroom experiments and hobbyist applications.
