Pneumatic Components Series

SOLH CXS high-rigidity thin twin rod cylinder is fully interchangeable with original SMC CXS series. Constructed with integrated coaxial dual pistons and dual guide rods for synchronous actuation, it delivers nearly doubled thrust versus single-piston cylinders of identical bore size with stable anti-rotation accuracy of ±0.1°. Its integrated guiding structure provides strong resistance to lateral and eccentric loads without external auxiliary guides. Four core sub-models are available: CXSM with metal slide bearing boasts outstanding wear resistance, dustproof performance and superior side load capacity for low-speed positioning, pressing and dusty environments; CXSL ball bearing type features ultra-low friction and smooth movement with maximum speed up to 400 mm/s for high-frequency high-speed pick-and-place; CXSWM/CXSWL double through rod versions allow fixture installation on both rod ends for bilateral synchronous lifting and centering transfer. Dual-end rubber buffers are standard; AZ air buffer is optional for φ20/25/32 large bores to absorb violent high-speed impact. Suffix Z denotes built-in magnetic rings for direct installation of D-M9B, D-A93 and other position sensors; non-magnetic variants are available for magnetic-sensitive working conditions. Optional extension lock P and retraction lock R can lock the piston at designated positions. Three-side mounting (bottom, top, side) supports diverse compact mechanical layouts, widely deployed in precision picking, material transfer, positioning and light pressing processes for 3C electronics and general automation production lines.

SOLH TN cost-effective twin shaft cylinder adopts a single-piston dual guide shaft structure with slide bearing guidance for compact layout and excellent cost performance. It comes factory-equipped with built-in magnetic rings and an adjustable front rubber buffer for stroke fine tuning, delivering anti-rotation accuracy of ±0.2°. Synchronized dual shafts restrain torsion and swing to bear slight lateral eccentric loads. Three-direction mounting (top, bottom, side) is available, and side grooves support direct installation of magnetic switches without extra brackets. Two types are supplied: standard single-end rod TN and double through rod TNW, with TNW allowing fixture assembly on both rod ends for bidirectional synchronous centering motion. Compared with TR series, TN features smaller dimensions and lower cost without φ6 bore option; compared with CXS/CXSJ dual-piston twin cylinders, TN outputs single thrust with obvious cost advantages yet lower precision and load capacity. Its working pressure ranges from 0.15 to 1.0 MPa and ambient temperature adaptability covers −20℃~70℃. It is widely used for light-load positioning, simple pressing, workpiece stopping and short-distance transfer for general automation stations with moderate precision requirements and cost control demands. The S-type magnetic ring is standard for the whole series and cannot be removed; default Rc thread can be customized to G thread or NPT thread for overseas projects.

SOLH TR twin shaft cylinder is manufactured in accordance with JIS industrial standards. It adopts a single-piston dual guide shaft structure matched with extended slide bearing bushes, featuring high structural rigidity, excellent torsion resistance and strong anti-deflection capacity superior to cost-effective TN twin shaft cylinders. Bore sizes range fully from φ6 to 32 mm, including standard single-rod TR, double through rod TRW and lightweight compact TRJ variants. Anti-rotation accuracy reaches ±0.1° for bores ≥16 mm and ±0.2° for φ6/φ10 small bores; dual shafts restrict swinging deviation to guarantee stable operation over long strokes. An adjustable front rubber cushion pad cooperates with fixed rear buffer for stroke trimming, impact absorption and noise reduction. Three-way mounting (top, bottom, side) and optional dual-side porting are available; side grooves allow direct assembly of magnetic switches without extra brackets. Built-in magnetic rings marked suffix S are standard, while non-magnetic customized versions are offered for magnetic interference sensitive occasions. Operating pressure ranges 0.15~1.0 MPa with working temperature from −20℃ to 70℃. Standard Rc thread can be converted to G thread or NPT thread for overseas engineering projects. Distinguished from CXS twin cylinders: TR outputs single thrust with prominent mechanical rigidity and stable side-load resistance in long-stroke applications; CXS features dual pistons for double thrust, lower friction and smoother high-speed reciprocation suited for high-frequency short-stroke pick-and-place. Widely applied in precision positioning, workpiece pressing, long-distance stopping & transfer and general automation stations requiring reliable guiding under medium-light loads.

SOLH MK (commonly named MKB) is a combined pneumatic cylinder integrating 90° rotation and linear downward clamping, interchangeable with mainstream MKB series. Bore sizes cover φ12~φ63 and clamping strokes range from 5 mm to 50 mm. Its overall length is shortened by 3~10 mm compared with conventional MK2 models for more compact layout. The allowable inertia torque is upgraded threefold to cope with high-speed clamping of high-inertia workpieces, and the maximum clamping force of φ63 bore reaches 12.4 kN under 0.5 MPa for reliable heavy-load holding. Working cycle: retract upward → 90° left/right rotation → extend for clamping; release follows reverse sequence. Fixed 90° rotation angle with tolerance ±5° ensures stable repetitive positioning. Except φ20 and φ25 bores with 2-side sensor mounting only, other sizes support 4-direction magnetic switch installation for neat wiring without interference. Through holes and double-end threaded holes enable direct mounting and flange installation. Double-side rubber buffers reduce impact, vibration and noise; oil-free design satisfies clean & dust-free working environments. Built-in magnetic rings work with position sensors to monitor clamp/release status; clockwise RZ and counterclockwise LZ rotation directions are optional. It is widely applied in machine tool fixtures, welding positioning, stamping fixing, precision 3C components, semiconductor tray clamping and fixture flipping limiting. It simplifies mechanical design and saves installation space by integrating rotating and clamping functions. Select bore size with clamping force ≥ actual load × 1.5 safety factor and reserve 3~5 mm stroke margin to avoid mechanical collision.

SOLH ACK angle cylinder integrates integrated compound motion of standard 90° rotation / optional 180° turning plus linear downward clamping, with bore sizes ranging from φ25 to φ63. It features a three-guide-groove supporting structure as the core design, which brings superior structural rigidity and strong resistance to eccentric loads, achieving high angular positioning accuracy of ±1.5°, better than ordinary rotary clamp cylinders. Two structural types are available: ACK with single pressure plate for narrow workpieces and ACKD double pressure plate for wide workpieces; counterclockwise left rotation (L) and clockwise right rotation (R) are selectable to match on-site layout. Working cycle: piston rod retracts and lifts up → rotates to avoid workpiece interference → extends downward for clamping; release runs in reverse order for resetting. The piston rod is made of heat-treated alloy steel, the cylinder tube undergoes hard anodizing, matched with imported high-performance sealing rings to realize excellent wear resistance, corrosion resistance, low air leakage and long service life. Four bottom through holes support direct installation and flange mounting; built-in sensor grooves facilitate magnetic switch assembly to monitor clamp and release status. Each bore is equipped with fixed standard clamping stroke; the maximum clamping force of φ63 reaches 1050 N under 0.5 MPa operating pressure. The working pressure ranges 0.15~1.0 MPa with wide temperature adaptability from −20℃ to 80℃. It is extensively adopted in machine tool tooling, welding positioning, anti-shifting fixing for stamping processes, fixture clamping of electronic trays and positioning for turnover mechanisms. It replaces separate rotary and clamping cylinders to simplify mechanical layout and save installation space. Select proper bore size with theoretical clamping force ≥ actual load × 1.5 safety factor, and reserve 3~5 mm stroke margin against mechanical collision.
