ASG - INFINITY High-Performance AEG Motor CNC U-18000 Long Axle
Built to deliver brute torque with unwavering consistency, the ASG INFINITY High-Performance CNC U-18000 Long Axle Motor is a powerhouse for serious airsoft custom builders. Clocking in at approximately 18,000 RPM, this motor is engineered for high-drag builds, such as Designated Marksman Rifles (DMRs) or torque-demanding gear sets. If your goal is controlled, precise shots over raw rate of fire, the U-18000 is a perfect fit — especially when used with M95 to M115 springs from the ULTIMATE Mil-Spec range.
Every part of this long axle motor is precision-crafted using CNC machining to ensure the highest standard of fit and performance. It features CNC aluminium end caps, a steel pinion gear, and a stainless steel shaft, all encasing a powerful silicon steel rotor. Rare-earth magnets provide thermal stability and improved magnetic efficiency, while oversized carbon brushes and silver-plated wiring ensure optimal electrical transfer. With a design focused on durability and high-torque output, the U-18000 is ideal for expert-level builds where performance under pressure is critical.
