Technic, Axle

Drive motion and structure in your builds with LEGO Technic axle parts—key components that connect, rotate, and support mechanical functions. These long, rod-like elements serve as the backbone for moving parts in LEGO Technic sets, offering strength, precision, and alignment across a wide range of creations.

LEGO Technic axles come in various lengths and colors, typically measured in module units. You’ll find straight axles, stop-axles, and even axle-pin hybrids that allow seamless integration with Technic beams, gears, connectors, and wheels. Their cross-shaped profile ensures a tight grip and precise fit with Technic gear teeth and rotating parts.

You’ll find Technic axles in nearly all mechanical themes, including LEGO Technic, Mindstorms, and Control+. Builders use them to transmit power from motors, link moving components, or anchor structures that require rotational support. From complex gearboxes and robotic arms to steering systems and vehicle chassis, axles are essential for both structural integrity and functional movement.

These axles are designed for low friction and high strength. This allows for smooth rotation while maintaining durability under tension or torque. In many builds, Technic axles act as both connectors and motion drivers, reducing the number of elements needed to support mechanical systems.

Whether you’re creating a simple pulley or a multi-speed transmission, LEGO Technic axles provide the control and reliability required for advanced engineering. Their compatibility with LEGO gears, bushings, and beams makes them a must-have for custom MOCs, robotics, or any build that moves.

Strengthen and animate your designs with LEGO Technic axle parts—where every spin, turn, and movement starts with precision.
