About the Airtac SC40 Standard Cylinder SC40X920
The AirTAC SC40X920 is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa, making it suitable for medium-duty linear actuation across a long 920 mm working stroke. Its 16 mm diameter piston rod and PT1/4 ports provide a robust connection for air supply, while the 21 mm adjustable cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.
With a body length A of 142 mm, the total extended length reaches approximately 1062 mm. This model is a genuine AirTAC SC tie-rod cylinder, engineered for reliable performance in applications requiring a compact yet powerful actuator. The standard TPU seals ensure reliable operation within a temperature range of -20 to +70 °C.

Where the Airtac SC40 Standard Cylinder SC40X920 Is Used
Material Transfer
Pushes or lifts components along a 920 mm path on packaging or assembly conveyors, handling moderate weights with the 628 N force at standard plant pressure.
Clamping & Fixturing
Provides a long-reach clamping action for woodworking or metal fabrication jigs, where the 920 mm stroke securely holds large workpieces in place.
Bin Pushing
Actuates a pusher plate to divert or index bins and cartons on gravity or powered roller conveyors in distribution centers.
Is the Airtac SC40 Standard Cylinder SC40X920 the Right Cylinder?
Selecting the SC40X920 means choosing a 40 mm bore cylinder for a 920 mm stroke application. If your force requirement is slightly lower, the 32 mm bore offers 402 N at 0.5 MPa; for higher force, stepping up to the 50 mm bore provides 982 N. Always match replacements by bore, stroke, PT port thread, and basic mounting configuration. For this 920 mm stroke, ensure the rod is supported against side loads—consider an external guide or a guided cylinder if the load is not purely axial, as a long, unsupported 16 mm rod can be susceptible to bending under lateral forces.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC40 Standard Cylinder SC40X920 FAQ
At 0.5 MPa (approximately 73 psi), the SC40X920 generates 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552 profiles. Replace only with another AirTAC SC40 cylinder of matching stroke, port, and mounting.
