Guanshuo China factory mass-produces high-precision servo motor shafts. Adopting CNC turning and ultra-precision grinding technology, the measured coaxiality is strictly controlled within ≤0.005mm, and the dynamic balance correction can reach G1 grade. The lightweight low-inertia structure greatly improves the high-speed response speed of servo equipment. The shaft supports three hardening processes: nitriding, chrome plating and surface quenching. Custom structures such as taper, spline, internal thread and keyway are available to match encoders and couplings. The factory owns 11 shaft patents and ISO9001 qualifications, provides free sample test reports and a unified 24-month warranty, serving as the core transmission parts for procurement of high-end precision servo equipment.

Below are frequently asked questions from global purchasers about servo motor shaft precision, customization, service and performance, with detailed real-data answers based on official product specifications and factory standards.
A: Our servo motor shaft adopts CNC turning and ultra-precision grinding process with stable finished coaxiality ≤0.005mm. Extremely low radial runout greatly reduces friction vibration and operation noise during high-speed running, eliminates positioning offset after long-term operation and maintains micron-level repeated positioning accuracy of automated equipment without decay.
A: All finished products go through independent dynamic balance correction to reach top industrial G1 grade. Compared with conventional G2.5/G6 motor shafts, vibration and noise are greatly reduced at high rotating speed, perfectly suitable for long-time continuous high-speed operation of silent precision servo equipment without jitter or abnormal noise.
A: Three mature surface strengthening processes are optional: surface quenching, nitriding and chrome plating. Hardened shaft surface gains higher hardness and wear resistance, maintaining original precision after long-term non-stop operation and effectively extending the whole service life of servo motors.
A: Customizable structures include 1:10 standard taper, M4~M12 internal thread, keyway, spline, double step and taper surface. Structural sizes can be adjusted according to encoder, coupling and brake assembly drawings to quickly match non-standard servo systems and shorten project delivery cycle.
A: Yes. Standardized CNC processing, grinding and dynamic balance procedures with fixed parameters. Every batch undergoes full inspection via 2D projector, dynamic balance tester and roughness meter with complete test reports. Coaxiality, runout and balance grade are highly unified for strong assembly interchangeability.
A: Applicable to CNC processing equipment, automatic transplant sliding tables, precision testing instruments, new energy lithium battery processing equipment, intelligent warehouse sorting equipment and all industrial automation devices equipped with servo drive systems requiring high positioning accuracy and fast response.
A: Free sample trial production is supported. Complete dimensional test reports, dynamic balance records and material process certificates can be supplied for each batch before delivery.
