Heavy Thrust in Slim Body
Generates 100N to 300N of maximum push/pull force from a compact Ø13mm or Ø16mm outer diameter, enabling ultra-tight spacing in multi-axis fixtures.
±0.02mm Micro-Repeatability
Precision-ground planetary roller/lead screw mechanics provide deterministic, repeatable sub-millimeter positioning without overshoot or thermal drift.
Brushless Motor Reliability
High-torque brushless DC core motor architecture eliminates brush wear and carbon dust, ensuring long operating life and cleanroom compatibility.
Standardized DF-10PIN
Single integrated DF-10PIN connector carries power, control signals, and feedback, drastically reducing harness bulk inside robotic arms and dexterous hands.

Slim Ø13-16mm profiles allow mounting directly inside forearm arrays or multi-finger bases to actuate tendon cables or pushrods with up to 300N of gripping force.
Medical & Laboratory Automation
Zero hydraulic fluid, zero pneumatic compressor requirements, and cleanroom-compatible brushless design make it the gold standard for pipetting, syringe pumps, and specimen positioning.
Semiconductor & Optical Alignment
±0.02mm repeatability and deterministic position holding under load ensure microscopic alignment stability for lenses, wafer clamps, laser positioning, and die-head adjustment.
Frequently Asked Questions
How does the ZHR-BC series compare to conventional pneumatic cylinders?
Unlike pneumatic cylinders that only stop at two fixed ends and require compressed air lines, valves, and noisy compressors, ZHR-BC provides fully programmable multi-point positioning, controllable thrust (up to 300N), ±0.02mm repeatable accuracy, and quiet, energy-efficient electric power.
What is the difference between ZHR30-100, ZHR30-300, and ZHR25-255?
ZHR30-100 is an ultra-slim Ø13mm, 12V unit with 30mm stroke and 100N maximum force for battery-powered or ultra-tight builds. ZHR30-300 is a 24V, Ø16mm unit delivering up to 300N of stall force with 30mm stroke. ZHR25-255 offers 25mm stroke with an integrated copper front guide sleeve for applications requiring superior lateral rigidity and up to 255N of stall force.
What interface and connector are provided?
All models utilize a standardized DF-10PIN connector. The pinout integrates motor power, ground, serial communication (RS485 / CAN depending on controller configuration), and internal position sensor feedback. Detailed wiring diagrams and pin definitions are included in the downloadable CAD package.
What is the prototype sample lead time and MOQ?
We maintain an engineering evaluation policy with an MOQ of just 1 unit. Standard prototype units are typically prepared and dispatched within 2 to 3 weeks via DHL/FedEx worldwide air express.
