Hengshui Machinery manufactures precision hydraulic cylinders for industrial automation: servo-controlled positioning systems, hydraulic clamping and fixture systems, stamping presses, injection moulding machines, transfer and assembly lines, and robotic end-effectors. Automation cylinders demand tighter dimensional tolerances, lower friction, higher positioning accuracy, and greater cycle-life consistency than many other cylinder types.
Our automation cylinders are produced to tighter bore tolerance (H7) and rod tolerance (h6 or g6) than general industrial cylinders, with special low-friction seal configurations (PTFE-backed or coated variants) for smooth servo response and minimal stick-slip. We manufacture precision bore tubes honed to Ra 0.2–0.4 µm, and offer integrated position transducer mounting provisions and magnetic piston options for reed-switch or Hall-effect position sensing.

Swing-arm, block, and hollow piston clamping cylinders for precision machining fixtures. High clamping force, repeatable position, no creep under machining loads.
Main ram cylinders for hydraulic blanking, punching, and deep-drawing presses. High-cycle, high-force; servo pressure control for variable force profiles.
Tie-bar cylinders and platen movement cylinders for injection moulding machines. Bore up to Ø250 mm; high-cycle; low-friction seals for precise clamp force control.
Precision stop-and-go indexing cylinders with integrated cushioning and end-of-stroke sensing for automated transfer line workpiece indexing.
Low-friction cylinders with integrated transducer mounting for closed-loop servo-hydraulic position, velocity, or force control axes.
Precision cylinders with extremely low friction for green compact and ceramic sintering press applications requiring precise force-displacement profiles.
Cylinders for body-in-white welding fixtures, part clamping jigs, and assembly robots in automotive manufacturing plants.
All products available with custom bore, stroke, seals, and surface treatment. OEM/ODM manufacturing from drawings or samples.
