SOLH C85/CD85 stainless steel mini cylinder complies with ISO 6432 international standard and can be directly interchanged with equivalent SMC models. Bore sizes: φ8/10/12/16/20/25 mm. Barrel and piston rod are made of 304 stainless steel with excellent rust and corrosion resistance, applicable to humid, mild acid & alkali environments, as well as clean production lines for food, pharmaceutical and electronics industries. Adopting tie-rod-free crimped end cap structure, the cylinder features slim and lightweight design. Complete variants include standard double acting, single acting spring return/extend, double rod synchronous type and C85K square non-rotating rod cylinder. CD85 versions are equipped with built-in magnetic ring for position detection via magnetic switches. Standard rubber cushion is supplied; suffix C air cushion is optional for φ10~25 models to absorb impact under high-speed operation. The minimum starting pressure reaches 0.05MPa, supporting long-term oil-free operation with piston speed from 50 to 1500 mm/s, perfect for high-frequency short-stroke reciprocation. Full sets of ISO standard mounting options are available: integrated clevis, flange, foot mount, trunnion mount and more. Compared with MI and MA cylinders, C85 owns globally recognized ISO dimensions, bringing outstanding convenience for equipment replacement in overseas markets. A minimum 50% thrust safety margin is recommended during selection.

SOLH CG3 ultra-short lightweight pneumatic cylinders serve as an upgraded replacement for traditional CG1 series round actuators. Constructed with high-strength aluminum alloy barrel and end caps paired with hard chrome-plated piston rods, this series cuts overall weight by 24% and shortens total length up to 51mm for remarkable space optimization. Available in bore sizes ranging from φ20mm to φ100mm, it supports four-direction air port arrangement to enable flexible piping layout inside compact machinery. Multiple structural variants cover double-acting, spring single-acting, double-rod and hexagonal anti-rotation piston rod versions to satisfy diversified linear drive demands. Standard rubber cushion mitigates mild end impact, while optional air buffer suits high-speed operation up to 1000mm/s. Low-friction composite sealing realizes oil-free operation with service life exceeding 8 million working cycles; CDG3 magnetic integrated models support magnetic switch installation for PLC position feedback and automatic linkage control. We maintain stable mass production and sufficient spot inventory, widely applied in packaging equipment, electronic assembly lines and general light industrial high-frequency automation with outstanding cost efficiency.
