[RETRO ARMS] CNC Low Profile Bushing 6mm, 7mm, 8mm, 9mm / 3mm

This is a high-strength, thin bearing machined from 90MnCrV8 tool steel.
The compatible gear shaft is Φ3mm, and the bearing hole sizes are 6mm, 7mm, 8mm, and 9mm.
One package contains 6 pieces.

The surface is blackened to prevent rust and coated with rust-preventive oil.

For overseas-made gear shafts with negative tolerance (approximately Φ2.95mm).
Cannot be used with Tokyo Marui genuine gears that have a thick shaft diameter.

The dimensions are thin, at approximately 2mm thick (flange thickness 0.5mm), and it is almost flush with the gearbox, so it does not interfere with the frame and selector plates other than those compatible with 8mm or 9mm bearings can be used.

This bearing is very hard, at HRC 58-60, so when using gears such as those made by Siegetek Concepts, which have a similar hardness, be sure to use an extreme pressure lubricant that is excellent at lubricating metal to metal.
(Teflon and silicone lubricants are not recommended.)
