Plastic pully 47mm x 20mm bore dia 6.5mm

Plastic Pulley 47mm x 20mm Bore Dia 6.5mm

The plastic pulley is a lightweight yet durable rotating component designed for DIY mechanisms, robotics projects, and educational prototypes. Because it pairs well with plastic gears and other motion-transfer parts, this pulley is widely used in motorized systems that require smooth, low-friction movement. Its strong build also makes it suitable for small machines where an acetal pulley alternative is required without compromising stability.

With a diameter of 47mm and a precise 6.5mm bore, this plastic  pulley fits most standard shafts used in robotic platforms and mechanical assemblies. Its balanced structure ensures consistent rotation, which is especially useful when working on pulley reduction setups, belt-drive systems, or STEM engineering activities. Additionally, makers who frequently build plastic gears based mechanisms will find this pulley extremely convenient due to its compatibility and easy installation.
