Reduce rotating mass without losing useful stiffness
Hollow sections and material transitions need enough structure around journals, shoulders and torque-transfer features while meeting the mass target defined by the motor design.
A fast control loop still depends on physical geometry. Shaft mass distribution, runout, straightness and torque-transfer interfaces can return as vibration, noise or inconsistent assembly after the component enters the motor.
YUBAO manufactures drawing-based precision motor shafts, hollow shafts, friction-welded shafts, spline shafts and gear shafts for servo motor and industrial automation projects.

YUBAO reviews the supplied drawing around mass distribution, torque transfer, fit and repeat production, then connects hollow geometry, welded structures, splines and gear features to a practical manufacturing route.
Hollow sections and material transitions need enough structure around journals, shoulders and torque-transfer features while meeting the mass target defined by the motor design.
Journals, shoulders, splines and gear features need a controlled datum chain. Radial error can otherwise return as vibration, noise or difficult assembly.
Torque-transfer and locating interfaces must assemble without forcing axial position, fit or concentricity away from the released drawing.
Machining, welding, treatment and final inspection must stay linked so later batches preserve the relationships approved in the first part.
Every product shown here belongs to YUBAO’s established manufacturing range. The final geometry, material, treatment and inspection scope remain controlled by the customer drawing.
Stepped shafts with drawing-defined journals, shoulders, threads and coupling features tied to one functional datum plan.

View hollow shafts →Different materials or section sizes joined before final machining of the datums that control the finished shaft.
View welded shafts →Torque-transfer shafts where engagement, fit, concentricity and the adjacent locating surfaces must work as one interface.
View spline shafts →Integrated gear-and-shaft components that reduce separate interfaces while preserving tooth-to-shaft alignment.
View gear shafts →Turning establishes the references. Hollowing and friction welding change the structure. Spline or gear machining, heat treatment and grinding then have to preserve the relationships defined by the finished-part drawing.
01Establishes journals, shoulders, threads and the datum references used by later operations.
02Controls wall thickness, internal transitions, concentricity and access for finish machining.
03Places the joint and machining stock so finished datums can be recovered after welding.
04Generates torque-transfer features while protecting the spline-to-shaft or tooth-to-shaft datum relationship.
05Finishes journals and runout-sensitive surfaces tied to concentricity, surface condition and final fit.
06Balances hardness, wear resistance and dimensional stability before final finishing.
A shaft can meet isolated dimensions and still create assembly or motion problems when journals, shoulders, splines and gear features do not relate to the same references. YUBAO focuses inspection on those drawing-defined relationships.
The agreed plan follows the part through machining, welding, treatment and final verification, giving engineering and purchasing evidence tied to the released drawing rather than a generic checklist.
Journals, shoulders, bores, splines and gear references are checked in the relationships that locate the component.
Rotating features are verified from the agreed references so radial error is not hidden by isolated measurements.
Engagement, profile, lead, pitch and tooth runout are inspected where the drawing requires them.
Joint control, material certificates, hardness results and treatment records can remain linked to the batch.
In-process checks, final inspection, CMM measurement and gear inspection are selected to match part risk.
Retained records and batch traceability give later orders a controlled reference to the approved sample.
Removing mass changes stiffness and machining access; friction welding introduces another structural transition. Early review connects the finished geometry, mating parts and production route before the design reaches tooling.
Each checkpoint answers a practical question before the next begins, keeping engineering, quality and purchasing aligned on what has been confirmed.

Send the drawing or sample together with speed, torque, duty cycle, target mass or inertia where relevant, mating-part information, material, treatment, quantity and estimated annual demand.
Yes. Hollow shafts are manufactured to the drawing, with wall thickness, datum structure, machining access and critical fit requirements reviewed before sampling.
The route can include joint-location review, welding control, post-weld machining and inspection of the finished datum and runout features.
Yes. Projects can begin with engineering review, samples or a controlled trial batch before repeat production is approved.
No. YUBAO manufactures drawing-based mechanical components including precision shafts, hollow shafts, welded shafts, spline shafts and gear shafts. Motors, encoders, brakes, drives and electronic controls remain outside YUBAO’s supply scope.
The material, heat treatment and surface-protection route is selected from the drawing, speed, load, wear and dimensional-stability requirements.
