Bushings are critical yet often overlooked components within AEG gearboxes. These cylindrical bearings support gear axles, ensuring smooth rotation and precise alignment under load. Understanding their function and upgrade options is vital for maintaining performance and preventing gearbox failure.

Why Upgrade Your Bushings?

Replace Fragile Polymer BushingsMost stock AEGs use polymer bushings prone to deformation, cracking, and accelerated wear. Upgrading to metal bushings (steel or brass) significantly extends gearbox life and operational reliability.

Prevent Catastrophic Gearbox Failure

Worn or cracked bushings allow gear misalignment, leading to stripped gears, piston damage, or seized gearboxes. Metal bushings provide essential structural integrity under stress.

Support High-Stress Builds

High-torque motors, heavy springs, or high-RPS builds exert extreme forces. Standard bushings may deform; purpose-built upgrades maintain stability under demanding conditions.

Sizing: Non-Negotiable Precision

Bushings are gearbox-specific. Common sizes:
6mm/7mm/8mm/9mm
Using incorrect sizes causes irreversible gearbox damage. Always verify your shell specifications before purchasing.

Choosing Reliable Upgrade Bushings

For optimal performance and longevity:

• Prioritize material quality: Hardened steel or precision brass resists deformation.
• Demand machining precision: Tight tolerances prevent gear wobble (0.01mm variance ideal).
• Match to your build goals: Standard for reliability, bearings for speed (with trade-offs).

Key Takeaways

• Metal bushings are mandatory for longevity beyond stock polymers.
• Size accuracy is critical – measure your gearbox first.
• Balance performance needs with durability when choosing type.
• Investing in precision-engineered bushings prevents costly failures and secures your AEG’s performance foundation.
