The diameter of the shaft that goes into the gearbox is Φ9.4mm to Φ9.95mm in 0.05mm increments.
There are a total of 12 different custom motor towers in the lineup.
By narrowing the clearance with the gearbox, the tilt of the motor inside the grip is suppressed.
This reduces noise. The dimensions of each part, except for the shaft diameter, are as shown in the photo.
The shaft length is compatible with various long standard motors.
Please measure the dimensions of the motor tower inlet of your gearbox and select the appropriate size.
There are two ball bearings at the tip and base of the motor tower.
