9mm open steel bearings (B9CA).
The adoption of these bearings reduces the friction due to the rotation of the gears.
This advantage translates into both a higher burst speed and a better use of the energy contained in the battery.
The open bearing guarantees greater resistance compared to the closed one because the ball bearings that compose it are of larger dimensions.
Another advantage of these bearings is the minimum thickness that does not interfere with the selector plate and the body of the rifles.
The dimensions are:
- external diameter: 9 mm
- internal hole: 3 mm
- thickness: 2.5 mm
