The 3411 Series pulley is specifically optimized for use in compact drives within the standard goBILDA U-channel. Its outside diameter is designed to maximize traction and belt contact area while still allowing sufficient space for the belt teeth to move freely relative to the channel walls. The 14 mm center bore allows the pulley to be used with large shafts or tubular axles.
The pulley is made of durable aluminum with a clear anodized finish. The standard goBILDA 16 mm mounting pattern is located around the center bore, making it compatible with all hubs in this series. The side flanges ensure that the 9 mm wide belt remains centered on the pulley even at high speeds or sudden changes in direction.

With 24 teeth, this pulley provides excellent torque transmission and minimizes the risk of belt slippage. The HTD (High Torque Drive) profile promotes smooth engagement, reducing noise and vibration in the drivetrain.
When installing inside the 1120 Series U-Channel, careful alignment of the shafts is recommended, as minimal clearances require high precision installation. To secure the pulley to the hub, use M4 screws that match the depth of your hub's mounting holes.
