WCP Aluminum HTD Timing Pulley – 5mm Pitch, 9mm Width, 1/2" Hex Bore

The WCP Aluminum HTD Timing Pulley from WestCoast Products (WCP) is engineered for high performance power transmission in robotics and automation systems. Designed to pair with 5 mm pitch HTD timing belts, this pulley offers a lightweight and efficient alternative to chain drives while maintaining the strength required for demanding applications such as FIRST Robotics Competition drivetrains.

Machined from high strength aluminum and finished with a black anodized coating, it delivers precise motion transfer, excellent wear resistance, and long service life. The 1/2 in hex bore allows for direct integration with common FRC hex shafting, simplifying installation and ensuring secure torque transfer.
