About the Airtac SC40 Standard Cylinder SC40X600
The AirTAC SC40X600 is a double-acting tie-rod cylinder delivering 628 N of push force and 528 N of pull force at 0.5 MPa. With a 40 mm bore and 600 mm stroke, it operates on filtered air from 0.15 to 1.0 MPa, providing a maximum theoretical thrust of 1130 N at 0.9 MPa.
This model features a 16 mm diameter piston rod with M12x1.25 threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston at end-of-stroke to reduce impact. Its body length A is 142 mm, resulting in a total extended length of approximately 742 mm. Standard TPU seals suit a -20 to +70 °C range.

Where the Airtac SC40 Standard Cylinder SC40X600 Is Used
Material Handling Gates
The 600 mm stroke and 628 N push force at 0.5 MPa efficiently operate diverter gates and stops on medium-duty conveyor lines.
Clamping & Fixturing
Provides consistent clamping force for woodworking or light metal fabrication jigs, with adjustable cushioning to protect the fixture.
Packaging Pushers
Ideal for case packing and palletizing systems where a 600 mm reach is needed to transfer products onto a conveyor or pallet.
Is the Airtac SC40 Standard Cylinder SC40X600 the Right Cylinder?
For higher force requirements, consider stepping up to the SC50 bore, which provides 982 N at 0.5 MPa. If space is constrained, the SC32 bore offers 402 N at 0.5 MPa. This 600 mm stroke exceeds 300 mm, so external guides or a guided cylinder are recommended to protect the 16 mm rod from bending under side loads.
When replacing an existing cylinder, match five key points: 40 mm bore, 600 mm stroke, PT1/4 port thread, basic mounting (no bracket), and the absence of a magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC40X600 FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. Strokes of 300 mm or more, especially with the 16 mm rod, are susceptible to bending under side loads. An external guide rail or a guided cylinder is strongly recommended to prevent rod bearing damage and ensure reliable operation.
