ASG Infinity CNC Custom Airsoft AEG Motor – U-18000 High Torque (Long Axle)

Elevate your AEG’s performance with the ASG Infinity CNC Custom Motor U-18000 – Long Axle, engineered for serious airsoft techs and players who demand unmatched torque and build quality. Whether you're upgrading your DMR platform or enhancing a support weapon, this motor is built to deliver smooth, reliable power with extreme precision.

At the heart of this motor lies ASG’s commitment to performance and innovation. Crafted from CNC-machined aerospace-grade aluminum, the motor housing offers both heat dissipation and structural strength, ideal for intensive, sustained fire. Its CNC-machined chromoly pinion gear ensures long-lasting durability and resistance to wear—even in high-stress gearboxes.

Built for High Torque Performance

The ASG Infinity U-18000 motor is designed specifically for high torque builds, making it ideal for upgraded springs, longer barrels, or heavier bolt-action simulations in AEG platforms. Its 28 TPA (turns per armature) setup provides the torque you need to pull strong springs without overheating or excessive drain on your battery.

While many motors compromise between speed and strength, the U-18000 is tuned for torque-focused reliability—perfect for designated marksman rifles, support builds, and techs who prioritize power delivery over rate of fire. The 0.65mm armature wire supports a stable current flow while ensuring maximum efficiency under load.

Ultra Durable, Low Maintenance

Durability is where this motor truly shines. The chromoly pinion gear offers resistance to stripping and deformation, especially under high tension or with misaligned gears. Combined with the CNC body and neo magnets, the ASG U-18000 motor stands up to long-term use with minimal maintenance required. This makes it an excellent choice for players who put their gear through harsh environments or long skirmishes.

The neodymium magnets further enhance power retention and torque generation, giving you strong startup speeds even when paired with high gear ratios. Whether you’re running semi-lock builds, full-auto support, or precision fire, this motor’s engineering is optimized for long-term performance.

Compatibility & Application

This version of the ASG Infinity motor is the Long Axle variant, which fits most Version 2 gearboxes found in M4, M16, MP5, G3, and similar AEG platforms. If you’re running a standard AEG and looking to upgrade your internal motor for higher torque performance, this motor is a direct-fit solution.

Tech-friendly and purpose-built for power-hungry builds, it pairs excellently with reinforced gearboxes, M120-M150 springs, and upgraded pistons and gear sets.
