Retro Arms AEG CNC-Machined Low Profile 9mm Bushings (6 Pack) (GG07-04)

The Retro Arms CNC-Machined Low Profile 9mm Bushings are exceptional durability, improved gearbox performance, and reduced friction due to their precision CNC steel construction. The low-profile design prevents interference with the selector plate in V2 gearboxes, and the hardened steel makes them suitable for high-stress, high-power builds that would quickly wear out standard parts. 

Key benefits

• Increased durability and resilience: Made from hardened, high-grade CNC steel with a hardness of 58-60 HRC, these bushings are extremely resilient and ideal for high-power builds with strong springs that can exceed the lifespan of standard bushings.

• Improved performance and reliability: Precision machining minimizes friction between the gears and bushings, leading to smoother operation and greater reliability over time.

• Reduced friction: The manufacturing process is designed to reduce friction, which helps the gearbox run more efficiently.

• Low-profile design: The 2mm height of the low-profile flange solves common jamming issues with the selector plate in V2 gearboxes, which is a benefit over standard-height bushings.

• High-stress build compatible: Their hardened steel construction makes them suitable for high-stress builds where more conventional parts would fail prematurely.

• Smooth operation: The precision fit and smooth surface finish of the CNC-machined parts contribute to a "surgically smooth" operation of the gearbox. 

Important considerations

• Lubrication: These are metal bushings, not ball bearings, so they require regular lubrication with a product like Vaseline on the gear axis and bushing contact points to prevent friction and jamming.

• Increased resistance: While they last much longer, these hardened steel bushings will cause slightly more resistance to the gears spinning compared to standard ball bearings.
