SOLH CJ1 ultra-miniature pin pneumatic cylinder is interchangeable with equivalent SMC models, offered in φ2.5 and φ4 bore sizes. φ2.5 is single acting spring return only, while φ4 supports both single acting and double acting versions. Slim and ultra-lightweight (2~3.5g), it features no built-in cushion for rapid response. The rod-side air port can be rotated ±90° to facilitate tubing layout. External threads on both ends enable direct axial fixing without extra brackets. It delivers thrust ranging from 0.64 to 6.3 N at 0.5 MPa, suitable for micro loads below 100 g to avoid impact damage to delicate tiny workpieces. NBR seals support oil-free operation for clean environment. Widely applied in short-stroke high-frequency push-pull tasks including 3C button durability testing, chip ejection, micro component positioning, precision instrument fine-tuning and miniature actuators for medical devices. A thrust safety factor of at least 50% is recommended during selection.

VBI-24 medium voltage vacuum circuit breaker is a kind of indoor medium voltage switch equipment with 50Hz/60Hz three phase AC 24kV rated voltage, which combined the technology of the ABB corporation in Switzerland and developed in China. Product complies with the standard GB1984 & IEC62271-100. VBI-24VCB usually mounted into switchgear panel KYN28 and XGN. It is applicable in occasions with frequent operation, has functions of high-speed recloser, Multiple Opening/Closing, reliable mechanical interlock. It has fixed type & withdrawable type. It adopts the composite insulated material, there is no pollution and explosion danger, the insulation level is high. VBI-24 indoor medium-voltage sealed vacuum circuit breaker is suitable for air-insulated indoor switches and is used for control and protection in power grids with AC and rated voltage of 24KV and below. Vacuum circuit breakers are used in frequent It has extremely excellent performance in operation and situations where the circuit breaker current needs to be opened, fully meets the requirements of automatic closing, and has high reliable operation and service life.

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.
