Air Cylinder

SOLH HLS / HLSL twin-shaft slide cylinders adopt line-contact cross roller guides, delivering much higher rigidity, repeat positioning accuracy and eccentric load resistance than HLQ ball guide models. Two variants are available: standard HLS with side-mounted compact cylinder for medium-small loads without severe offset; symmetrical HLSL with centered cylinder and dual parallel rollers for heavy loads, large eccentric torque and ultra-precision demands. Bore sizes cover 6–25 mm and strokes 10–150 mm. Twin piston rods provide powerful thrust and anti-torsion performance, while built-in floating joints eliminate lateral deflection stress. The base supports 3-direction mounting holes, the slide carriage reserves multi-surface fixture threads & positioning pins, and magnetic ring plus sensor slots come as standard. Adjustable air buffers, hydraulic shock absorbers and external mechanical stops are optional accessories. Operating temperature ranges from -20℃ to 70℃. Widely used in semiconductor, medical automation, machine tool jigs and other heavy-duty ultra-precision transfer & clamping positioning stations.

SOLH MSQ rack-and-pinion rotary actuator is fully interchangeable with equivalent SMC rotary tables. Driven by symmetrical dual piston gear rack structure, it generates 3~4 times higher torque and superior radial & axial load capacity versus vane-type CRQ cylinders. Two grades are available: MSQB standard series with H9 tolerance and MSQA high-precision series featuring H8 fit and ±0.01mm repeat positioning accuracy. The rotary table is pre-machined with locating pin holes and fixture tapping holes, plus a central hollow through hole for wiring & tubing routing. Equipped with dual-end angle adjustment screws for infinitely adjustable swing range 0~190°, fixed 90°/180° swing variants are optional. Two damping solutions are offered: standard rubber bumpers and suffix-R integrated hydraulic shock absorbers (L low kinetic energy / H high kinetic energy). Dual piping layouts include default end-face ports and E side front ports. Built-in magnetic rings support M9BW reed switches to transmit position feedback signals to PLC. Frame sizes range from 10 to 200, pre-filled with long-life grease for lubrication-free operation. Widely applied to PCB optical inspection, microchip precision positioning, packaging direction switching, machine tool workpiece flipping and mini manipulator end rotary joints for indexing, turnover and multi-angle positioning automation.

SOLH MSZ three-position rack-and-pinion pneumatic rotary cylinders are dedicated rotary actuators engineered to achieve three-point locking positioning (left limit / intermediate stop / right limit), solving the limitation of conventional two-position rotary cylinders lacking mid-station positioning. This series only needs one 5/3-way center-pressure solenoid valve for full position switching, removing complicated dual-valve pneumatic circuits to simplify system layout and lower overall engineering costs. The intermediate locking position supports ±10° fine angular adjustment, while the left and right travel limits are separately tunable within 0~95°, delivering flexible multi-angle positioning. It is classified into four specifications: basic MSZB, high-precision MSZA, rubber buffer MSZB-R and hydraulic buffer MSZA-R. The dual-rack dual-piston internal structure effectively eliminates gear backlash and outputs steady torque during frequent position switching. The integrated rotary plate comes with reserved locating pin holes for direct workpiece installation, paired with a central hollow through-hole to pass wiring and air tubing neatly. Standard side sensor grooves fit D-M9B & D-A93 magnetic switches to realize real-time signal feedback of three working stations. MSZA boasts positioning accuracy up to ±0.02 mm, while hydraulic buffer variants absorb large collision energy perfectly for high-speed heavy-duty rotation. Adopting oil-free self-lubricating design for long-term stable running, this rotary cylinder is widely deployed in workpiece sorting diversion, multi-station indexing, electronic positioning inspection and packaging automated steering flip procedures.

SOLH HRQ dual piston rack & pinion rotary cylinder includes micro sizes HRQ2/3/7 and medium-to-large HRQ10~HRQ200 with infinitely adjustable swing angle 0~190°. It outputs higher torque and stronger bending/radial load capacity than vane rotary actuators. Three configurations are available: basic mechanical stop buffer (low-cost for light low-speed duty), -A integrated hydraulic shock absorber (high-speed heavy load precise stopping), and -A(S) hydraulic version with stainless steel end caps for humid & slightly corrosive environments. The rotary table features central hollow through hole for tubing and wiring, and side sensor slots compatible with universal magnetic reed switches. Micro models adopt bottom mounting holes while medium/large sizes provide multi-side mounting taps for flexible layout. Pre-filled long-life grease enables lubrication-free operation. Selection requires simultaneous verification of torque, radial/axial load and bending moment. Widely used for rotary indexing in automatic assembly, material sorting, packaging capping and jig turnover stations.

SOLH MHZ2 standard-stroke and MHZL2 long-stroke parallel air grippers are fully interchangeable with equivalent SMC models. Driven by symmetric dual pistons and precision linear guide rails for synchronous jaw movement, they deliver ultra-high repeat positioning accuracy of ±0.01mm with bore sizes 10/16/20/25 mm. Three actuation modes are available: D double acting for maximum clamping force and continuous mass production; S single-acting normally open, which automatically releases workpieces upon air cut to avoid crushing at hot stamping stations; C single-acting normally closed with spring holding force without air supply to prevent workpiece drop for overhead robot handling. A full range of interchangeable jaws (narrow, thin flat, side tapped for extended fixtures) and multiple body port layouts (standard side port, end side port, axial push-in port) are optional. Built-in magnetic rings work with M9BW reed switches to transmit open/closed position signals to PLC interlock systems. MHZ2 features short stroke and high cycle speed up to 180 cpm for tiny miniature parts, while MHZL2 adopts extended guide rails for wide opening stroke to handle deep-cavity molds and large thick plates. All jaws, fittings and sensors are cross-compatible between the two series. Widely deployed for PCB & chip sorting, precision hardware loading/unloading, packaging clamping and workpiece transfer at robot end effectors in 3C, hardware and packaging automation lines.

SOLH MHF2 ultra-thin dual-piston linear guide parallel air gripper is fully interchangeable with equivalent SMC models. Its ultra-flat body height is only roughly one-third of MHZ2, effectively reducing bending moment at robot end effectors. Bore sizes range from 8 to 32 mm. It is purely double-acting with built-in throttle valves for speed adjustment. Each bore offers three stroke variants: D short, D1 medium and D2 long, with repeat positioning accuracy ±0.04~±0.05 mm. Four-sided sensor grooves enable multi-direction mounting including bottom tapping and through-hole installation; -F single-jaw fixed type is optional. Φ25/32 large sizes adopt recirculating ball guides for enhanced rigidity. Built-in magnetic rings work with M9B/M9N/M9P reed switches for position feedback. Ideal for height-restricted compact spaces, miniature linear modules, small robot EOAT, semiconductor and 3C precision assembly. During selection, jaw overhang length must be limited and bending moment verified with a safety factor ≥1.5.

SOLH MHL2 rack-and-pinion wide-stroke parallel pneumatic gripper is fully interchangeable with matching SMC models. The rack & pinion transmission ensures synchronous jaw movement, providing high rigidity and powerful clamping force, suitable for both external clamping and internal expanding gripping. Bore sizes cover 10/16/20/25/32/40 mm with purely double-acting design. Each bore offers three stroke variants: D short, D1 medium and D2 long, with repeat positioning accuracy of ±0.1 mm. Integrated built-in dust wiper seals enable stable operation in dusty harsh environments such as machine tool workshops. Four-side sensor grooves support flexible multi-orientation installation. Sizes 10~25 adopt standard M5 ports, while 32/40 support optional G / NPT export threads. Effective clamping force decreases with extended jaw overhang; a safety factor ≥1.5 is required during load calculation. Widely used for sheet material, tray and heavy workpiece handling, machine tool loading/unloading and packaging automation for large-size component gripping.

SOLH MHS3 3-jaw and MHS4 4-jaw wedge-cam self-centering hollow pneumatic grippers are fully interchangeable with equivalent SMC models. Wedge cam transmission drives synchronous jaw centering, achieving repeat positioning accuracy of ±0.01 mm. Bore sizes range from 16 to 125 mm. Standard double acting (D) design, with optional single acting normally closed (C) / normally open (E) spring return versions. The central hollow through hole allows routing of air tubes, ejector pins and optical fibers, supporting both external clamping and internal expanding gripping. Evenly spaced three jaws of MHS3 provide superior coaxiality, ideal for shafts, discs and ring-shaped workpieces. Orthogonally arranged four jaws of MHS4 deliver stable constraint for square, rectangular and irregular flat parts to avoid tilting. Built-in permanent magnets are compatible with M9BW series magnetic switches. The low-profile compact body fits robot end effectors perfectly. Derivative variants include dust-protected MHSJ3 and extended hollow MHSH3. Widely applied to machine tool loading/unloading, bearing press-fitting, handling of 3C circular & square components and concentric assembly of tubular workpieces.

SOLH MHC2 pivot-type angular swing pneumatic gripper is fully interchangeable with equivalent SMC models. A rocker arm mechanism drives jaws to rotate around the bottom pivot with maximum single-jaw swing angle of 30°, differing from linearly moving MHZ2 parallel grippers. Bore sizes cover 6/10/16/20/25 mm, available in D double acting and S single-acting normally open variants (no NC normally closed version). Built-in one-way throttle valves enable direct speed adjustment. Pre-installed magnetic rings work with M9BW reed switches to transmit jaw status signals to PLC systems. The low-profile compact body is ideal for outer wrapping clamping in equipment with limited in-depth space. Due to lever principle, effective clamping torque drops sharply with extended fixtures; load verification based on jaw overhang length is compulsory during selection. Widely applied for outer clamping of 3C plastic housings, bottle caps and tubular small parts, side feeding and pick-and-place for miniature robot end effectors. MHZ2 parallel grippers are recommended for applications requiring centered high-precision gripping, long fixture loads or power-off holding function.
