China air cushion oscillating cylinder Manufacturer, Supplier, Factory

SOLH RQ thin cylinder is interchangeable with SMC RQ/RDQ series. It adopts innovative ringless built-in air cushion structure with 3 times energy absorption capacity of CQ2 rubber buffer and 50% lower operating noise. The ultra-slim square barrel is 20% shorter than conventional air cushion thin cylinders, and mounting dimensions fit CQ2 and CQS for direct upgrade replacement. Variants cover non-magnetic RQ, magnet-equipped RDQ and lockable RLQ for vertical load anti-drop. Suitable for continuous high-speed reciprocation at 50~500mm/s. Bore sizes φ20~100mm and supports oil-free operation. Widely used in high-cycle automation loading/unloading, precision clamping and positioning requiring low impact and low noise.

SOLH SE tie-rod-free square standard cylinder complies with ISO15552 and VDMA24562 standards, directly interchangeable with FESTO DNC and SMC CP96S series. Integrated square aluminum barrel delivers high rigidity, fitted with double-end adjustable air cushion and 3-side sensor grooves for flexible installation. Variants include single rod, double rod, stroke adjustable and BSE lockable type, suitable for medium-heavy load and long-stroke high-frequency applications. Hard-anodized barrel supports oil-free operation with multiple mounting options, widely adopted for machine tools, packaging and conveyor automation. Custom long-stroke service, sufficient stock and stable bulk supply for global automation manufacturers.

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.

A Switchgear Drawer Microswitch is a vital component in the operation and safety of electrical switchgear systems. Designed for precision and reliability, this microswitch is typically installed within the switchgear drawer mechanism to detect and signal the position of the drawer—whether it is fully inserted, withdrawn, or in an intermediate position. The microswitch operates by actuating when the drawer moves, sending an electrical signal that can control various interlocking and safety functions.
