The AirTAC Airtac SC32 Standard Cylinder SC32X820S is a genuine double-acting standard air cylinder with a Ø32mm bore and 820mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X820 is a double-acting tie-rod cylinder delivering a push force of 402 N at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). Its 12 mm diameter piston rod and 21 mm adjustable air cushion are sized for moderate, repetitive linear tasks. The 820 mm stroke sits within the 1000 mm maximum standard stroke for this 32 mm bore, making it a readily available configuration.
With a body length A of 140 mm, the total extended length reaches approximately 960 mm. The PT1/8 port and M10x1.25 rod thread connect easily to standard pneumatic circuits. This genuine AirTAC SC cylinder is built with a TPU/NBR seal package rated for -20 to +70 °C and is filtered-air ready at 40 µm.

The 820 mm stroke pushes lightweight diverters or gates on packaging conveyors, routing products between lanes with the 402 N force available at 0.5 MPa.
Applies 724 N of push force at 0.9 MPa for pressing bushings or pins into light assemblies, with the adjustable cushion softening end-of-stroke impact on delicate parts.
Extends a labeling head or ink stamp across an 820 mm reach. The tie-rod design allows easy maintenance in high-cycle labeling stations.
Choose the SC32X820 for light-duty pushing, sorting, or clamping where the 402 N force at 0.5 MPa is sufficient. If the load requires more force, step up to the SC40 bore, which provides 628 N at the same pressure. For strokes of 300 mm or more, always check for side loads—an unsupported 12 mm rod at 820 mm extension is vulnerable to bending. Use an external guide rail or switch to a guided cylinder if the load is not perfectly axial.
When replacing an existing cylinder, match five points: 32 mm bore, 820 mm stroke, PT port thread, basic (no mounting accessory) configuration, and the absence of a magnet. This ensures a direct drop-in fit for another AirTAC SC32 tie-rod unit.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
No. The SC32X820 is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. To hold a load without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
