China Electrical Switchgear Interlock System Manufacturer, Supplier, Factory

SOLH MGP series thin compact guide rod cylinder is dimensionally interchangeable with genuine SMC products. It adopts an integrated structure of cylinder barrel, dual guide rods and precision bearings with built-in torsion resistance and powerful lateral load capacity without external guiding accessories. Its flat slim structure cuts 17%~24% weight compared with conventional cylinders, perfectly suitable for compact automation operations such as pressing, positioning, lifting and workpiece transfer. Three sub-types classified by bearings cover diverse working conditions: MGPM with metal sliding bushings features outstanding wear resistance and dustproof performance for heavy lateral loads and dusty low-speed cyclic work; MGPL ball bushings deliver ultra-low friction and smooth motion for high-speed frequent reciprocation; MGPA zero-clearance high-precision ball bearings achieve anti-rotation accuracy up to ±0.01mm for precision fitting and calibration. Bore sizes range from φ12 to 100 mm with standard strokes of 5~300 mm. Standard dual-end rubber buffers are equipped, while AZ air cushion buffers are optional for bores above 20 mm to absorb severe impact during high-speed heavy-duty movement. Built-in slots support direct installation of D-M9, A93 magnetic switches without extra brackets for tidy wiring. Operating pressure ranges from 0.12 MPa to 1.0 MPa with a minimum actuating pressure of 0.1 MPa under ambient temperature of -10℃~60℃. Widely deployed in electronic PCB positioning & pressing, inspection jig lifting, packaging feeding and general automation limiting clamping, it acts as a highly versatile integrated guided pneumatic actuator.

SOLH VT325 direct acting 3-port poppet solenoid valve adopts full elastic sealing and supports zero-pressure startup, operating stably under 0–1.0MPa positive pressure and full vacuum down to -101.2kPa. Six switchable circuit functions are integrated in one valve for wide versatility. Optimized internal flow channel delivers ultra-high flow capacity with C=6.1 dm³/(s·bar) and response time ≤30ms, ideal for high-flow rapid pneumatic switching. It features lubrication-free elastic seals and standard non-locking manual override, supporting single piping or dense manifold stacking for valve islands with Rc1/4 & Rc3/8 ports. Widely used in robotic arms, vacuum adsorption, air blowing, packaging, textile and woodworking automation equipment.

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 I type single clevis joint for pneumatic cylinder rod end, low cost U clevis hinged connector with ±5° swing. Carbon steel / stainless construction, female thread M10×1.25 M36×2.0 matching 32-200 mm bore cylinders, pin hole φ10-36 mm. AirTAC/SMC/domestic naming compatible (F M10×1.25I, I 32, CA2 40 I). Ideal for push pull loads, linear guides and flipping mechanisms.
