SOLH HFR pivot-linkage 180° wide-opening pneumatic gripper is driven by piston linkage to rotate jaws. Each jaw swings up to 90°, forming a straight line when fully opened to provide maximum clearance and eliminate mechanical interference during pick-and-place. Bore sizes cover 10/16/20/25/32 mm with purely double acting design. The -2°~-5° overclose angle ensures stable clamping. Three mounting surfaces (side, bottom, rear) are available; locating pin holes on the base improve assembly accuracy, and suffix-N through-hole mounting is optional. All models come with built-in permanent magnets and sensor grooves compatible with CMSH magnetic switches. Optimized dust-proof jaw structure and anti-friction metal separators deliver service life over 5 million cycles for moderately dusty workshop environments. Widely used for gripping and turnover of deep-cavity workpieces, large plastic housings and box materials. MHW2 gear-driven swing gripper can be considered for medium-load applications if extreme avoidance clearance is unnecessary. A minimum 30% safety margin must be reserved during torque calculation; extended jaw overhang greatly reduces effective clamping torque.

SOLH MBB lightweight tie rod standard cylinder is an upgraded lightweight model, 10% lighter than traditional MB series and fully compliant with ISO15552 standards for direct replacement of imported tie rod cylinders. Featuring double-end adjustable air cushion and square end caps, it ensures high rigidity, low noise and stable oil-free operation, suitable for medium-load and high-frequency working conditions. It covers multiple variants and diverse mounting options, widely used in conveying equipment and general automation machinery. With mature mass production and sufficient stock, it supports stable batch supply and exports worldwide.

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.

FZRN21 series Ac and HV indoor vacuum load break switch, this product has a breaking capacity, safety and reliability, long life, can operate freguent, compact structure, small size, light weight, the basic no need to maintain. FZN21-12 series high-voltage vacuum load switch is mainly composed of framer, disconnecting switch (current-limiting fuse of the combiner is in the disconnecting switch), vacuum switching tube, grounding switch, spring operating mechanism and so on. This product has compact structure, small volume, long life, strong closing and breaking capacity, and easy operation and maintenance. The vacuum switch is equipped with a spring-operated mechanism, which adopts an electric motor (another manual) spring energy storage, and there are two types of closing methods: electromagnet closing and manual splitting and closing. The disconnecting switch, vacuum switch and earthing switch are interlocked with each other (mechanical interlocking) to prevent misoperation. FZN21-12D/T630-20, FZN21-12DR/T125-31.5 type high-voltage vacuum load break switch and fuse switch are operating in three-phase AC electrical 12kV, 50Hz power distribution system, with a compact, small size, light weight, long service life, high making and breaking ability, safe and reliable, and if load switch cooperated with fuse namely fuse switch can replace those fuses with higher cost, easy and convenient operation and maintenance
