Hollow Shaft Electric Cylinders

Coaxial Rotary-Linear Actuators for Complex Multi-Axis Automation & Seamless Internal Routing

 

Hollow Shaft Electric Cylinders are next-generation precision linear actuators engineered with an integrated through-axis hollow bore. This coaxial architecture allows high-flex electrical cables, pneumatic hoses, vacuum lines, laser paths, or secondary drive shafts to pass directly through the center of the actuator, eliminating external mechanical interference.

 

By merging high-speed linear motion with a through-hole design, this series delivers unprecedented space savings and integration flexibility. It is the definitive solution for high-precision multi-axis automation, rotary-linear combined systems, and demanding industrial applications where traditional solid-shaft cylinders fail.

 

 
 

Operational Challenges We Solve

Eliminate Cable Fatigue & Failure

The hollow bore routes cables internally, completely preventing twisting, kinking, and snapping during complex 360° continuous rotary and linear motion.

Maximize Space Optimization

Replaces bulky external brackets and drag chains, combining linear and rotary mechanisms into one coaxial footprint—reducing your overall machine footprint by 25% to 40%.

Minimize Contamination Risks

Ideal for cleanroom environments such as semiconductor and medical lines. Enclosed internal routing locks friction particles inside, maintaining environment purity.

 

Technical Parameters & Standard Selection
 

Technical Note for Engineers:We utilize high-grade alloy steel ball screws (Precision Class C5 or C7) and integrated anti-rotation guide mechanisms to ensure maximum torsional rigidity. Custom backlash scaling ≤ 0.01 mm is available upon request.

FAQ

 

Q: What materials and components can safely pass through the hollow shaft?

A: Our hollow bores are engineered for high-flex electrical cables, sensor lines, pneumatic/vacuum hoses, cooling tubes, laser paths, or auxiliary mechanical rods. The internal bore features smooth, chamfered transitions to ensure zero abrasion to routing jackets.

Q: Can we use our own preferred brand of servo motors?

A: Absolutely. We provide flexible inline or foldback motor adapter plates customized to match your specified motor dimensions (such as Siemens, Rockwell, Fanuc, Panasonic,安川 Yaskawa, or Delta). Simply provide the motor drawing, and our team does the rest.

Q: How do you guarantee long-term reliability in vertical multi-axis installations?

A: For vertical installations, we equip the cylinder with an integrated anti-rotation guide mechanism and offer motors with optional electromagnetic safety brakes to prevent back-driving or axis dropping during unexpected power losses.

Q: Do you support low-volume prototype orders for R&D projects?

A: Yes. We fully support industrial innovation and offer an MOQ of 1 unit for initial engineering prototypes, backed by the same 48-hour CAD turnaround to support your strict R&D timeline.
