Custom CNC Turning Eccentric Hollow Shaft for Aerospace Parts & Components

Eccentric shaft refers to the CNC Turning Part whose axis of the outer circle and the outer circle are parallel but not coincident, generally fixed on the rotating shaft of the motor through the eccentric hole. The recess pressure on the eccentric shaft is different, which caused circumferential flow. The CNC machining eccentric hollow shaft is different from the eccentric solid shaft, the diameter of the hollow shaft is more than the solid shaft and require more space. Hollow shafts have a more polar moment of inertia, thus they can transmit more torque compared to solid shafts.

Dajin Precision Hardware Co., Ltd is an ISO 9001:2015 certified manufacturer of CNC turning eccentric hollow shaft for aerospace, mechanical, and more industries from prototype to production. Our CNC turning eccentric hollow shaft with its center offset from that of the axle, made of nodular cast iron or common metal treated with a machined surface finish. You can find various high-quality CNC turning shafts like servo motor shaft, aerospace drive shafts, laser shaft alignment, driven shaft for motor, horizontal shaft for cooled diesel engine, hollow eccentric shaft, precision aluminum shaft, machined brass shaft, linear drive shaft and more.
