CNC Machined Aluminum Timing Pulley

Machined from high-strength aluminum alloy, this timing pulley features a precision-machined outer groove profile designed to engage with synchronous belts for accurate rotary power transmission. The component integrates a central through-bore for shaft mounting, surrounded by a raised hub that ensures proper axial alignment and load distribution within the drive assembly.

Six evenly spaced clearance holes on the flange face facilitate secure bolting to mating hubs or motor shafts, while six threaded holes positioned on the pitch circle diameter allow for the installation of set screws or locking pins to prevent rotational slippage under torque. The uniform spacing and concentricity of these features are critical for maintaining dynamic balance and minimizing vibration during high-speed operation.

Production leverages CNC turning and milling capabilities to achieve tight tolerances on the bore diameter, groove geometry, and mounting interfaces. Our facility utilizes CMM inspection and dynamic balancing equipment to verify dimensional accuracy and rotational stability, ensuring reliable performance in automation systems, robotics, and precision machinery applications.
