Pneumatic Components Series

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.

SOLH MHY2 cam-driven 180° wide swing pneumatic gripper is fully interchangeable with equivalent SMC models. It adopts cam transmission instead of gear mechanism, achieving maximum 180° opening angle with -3° over-close position to prevent workpiece loosening. Bore sizes cover 10/16/20/25 mm, purely double acting without single acting NO/NC variants, and repeat positioning accuracy reaches ±0.02 mm. Optimized narrow clearance construction enhances dust resistance. Four-side sensor grooves are available, and through-hole mounting is optional. Built-in magnetic rings work with M9 series reed switches to send open/closed feedback signals to PLC. Due to lever transmission, effective clamping force declines sharply with extended jaw overhang; torque verification is required during selection, and clamping arm length is recommended within 35 mm. Ideal for picking and flipping large-diameter tubular and irregular workpieces at miniature robot end effectors. MHW2 gear swing gripper is recommended if power-off holding or larger heavy-duty bore is required; MHZ2 parallel gripper is preferred for centered linear clamping.

SOLH MHT2 toggle-joint heavy-duty self-locking pneumatic gripper is fully interchangeable with equivalent SMC models. The toggle linkage dead-point structure amplifies clamping force by 3~5 times. Mechanical self-locking engages once fully closed, retaining over 80% clamping force after air loss to prevent workpiece dropping, ideal for overhead robot handling and high-safety stations. Bore sizes cover 32/40/50/63 mm, offered in standard D type and updated lightweight DZ variant. Magnetic switches (M9BW) can be mounted on four sides for flexible sensor arrangement. Equipped with high-strength alloy steel jaws and wear-resistant linkages, it supports long-term oil-free continuous operation. Swing angle is limited within 23°~28°, so workpiece clearance must be verified during selection. Widely used for automotive components, cast & forged parts, heavy-duty machine tool loading and safety fixtures for pressing equipment. Unlike ordinary parallel grippers without locking function, MHT2 is the preferred solution for heavy loads requiring anti-drop protection.

SOLH MHW2 rack-and-pinion 180° swing pneumatic gripper is fully interchangeable with equivalent SMC models. Rack & pinion gear drive enables symmetrical synchronous jaw swing, each jaw rotates up to 90° for total 180° opening, with synchronization error ≤0.1° to guarantee balanced clamping and prevent workpiece slipping. Bore sizes range from 20 to 50 mm in purely double acting configuration. Jaws stand perpendicular to the body at full opening, minimizing occupied space and facilitating mechanical avoidance and workpiece flipping. Hard-anodized square aluminum body features four-side sensor grooves for unrestricted magnetic switch installation. Optimized dust-proof sealing supports long-cycle operation in dusty workshops. Compared with cam-driven MHY2, MHW2 delivers higher load capacity and better synchronization; unlike toggle MHT2, it has no power-off self-locking but provides far larger swing angle. Widely used for flipping and handling medium-load workpieces (1~20kg), cartons, large plastic parts and loading/unloading in confined automation stations.

SOLH MRHQ vane-type integrated rotary gripper is fully interchangeable with equivalent SMC models. It integrates a vane rotary module and parallel air gripper into a single actuator, replacing split combination of rotary table plus separate finger cylinder. Overall length is shortened by roughly 20% and tubing drag interference during rotation is eliminated. Bore sizes cover 10/16/20/25 mm with standard 90° and 180° rotation versions. End stop screws enable ±10° total angular fine adjustment. The double-acting parallel jaw achieves repeat positioning accuracy of ±0.01 mm. Five mounting surfaces together with locating bosses and pin holes enable fast centering and multi-orientation assembly. Built-in magnetic rings support up to four M9 series reed switches to detect both rotary limits and jaw open/closed status for full PLC interlock control. Adopting oil-free self-lubricating structure, it is widely used for workpiece gripping, flipping and direction conversion in confined-space 3C electronics and packaging automation lines for light & medium loads from 0.1 to 5 kg. A minimum 30% safety margin is required during load selection.
