Product Specifications

Technical details and manufacturing context for Drive Shaft/Bearing Assembly

Definition
The Drive Shaft/Bearing Assembly is a critical component of the Tool Arm that combines a rotating shaft with bearing support to transfer torque from the power source to the working end of the arm while maintaining precise alignment and minimizing friction. It enables smooth rotational motion and handles mechanical stresses during operation.
Working Principle
The drive shaft transmits rotational force from the motor or gearbox, while the bearing(s) reduce friction between the rotating shaft and stationary housing, supporting radial and axial loads to maintain alignment and rotational stability within the Tool Arm structure.
