Features:
Positive and negative, Center out shaft motor.
Ball bearings are used for special high speed special motors for water gun..The performance is stable and reliable, can be positive/reverse, the structure solid material obtains a lot of customer’s approval!.
The delay of the projectile is minimized, only because of its strong torque, which can push the spring every time.
Ball bearing configuration: ball bearing, the upper and lower parts, wear-resisting, Heat conduction slow.
