G&G Ball Bearing Bushing

You must check your specific gearbox shell specifications. These are designed exclusively for gearboxes that require 8mm bushings; they will not fit gearboxes designed for 6mm or 7mm sizes.

Ball bearing bushings reduce friction significantly compared to solid metal or nylon bushings. This reduction in friction allows your gears to spin more freely, which can lead to a slightly improved rate of fire and less strain on your motor.

Yes, like all moving internal parts, they should be lightly lubricated with a high-quality, airsoft-safe silicone grease. Avoid using heavy automotive greases, as they can attract debris and gum up the bearings over time.

While these bushings are durable, they are best suited for standard to moderate builds. If you are running an extremely high-stress setup with very heavy springs, solid steel bushings are often recommended to prevent the bearing cages from failing under extreme pressure.

The anti-heat design helps dissipate the friction-generated heat that builds up during sustained, rapid-fire sessions. By keeping the bushing assembly cooler, you reduce the risk of the lubricant breaking down and extend the overall lifespan of your gearbox internals.
