About the Airtac SC80 Standard Cylinder SC80X75CA
The SC80X75CA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 75 mm stroke, this model is configured with a rear single clevis (CA) mount, making it ideal for applications where the cylinder body needs to pivot during actuation.
This unit features a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 port connections. The total extended body length is approximately 257 mm, calculated from the 182 mm base body length plus the 75 mm stroke. It includes an adjustable air cushion (28 mm length) to decelerate the piston smoothly at the end of travel, reducing impact and noise.

Where the Airtac SC80 Standard Cylinder SC80X75CA Is Used
Dump Trailer Gate Actuation
The rear clevis mount allows the cylinder to pivot as it opens and closes a hopper or trailer gate, handling the 2513 N push force needed to move bulk materials reliably.
Clamping Fixtures
Provides 2513 N of clamping force at standard line pressure for holding workpieces in machining or welding jigs, with the clevis enabling a compact, swinging installation.
Diverter Gate Control
Operates a pivoting diverter arm on a conveyor system. The 75 mm stroke and adjustable cushion provide precise, soft-stop positioning for sorting packages or materials.
Is the Airtac SC80 Standard Cylinder SC80X75CA the Right Cylinder?
For applications requiring higher force, consider stepping up to the SC100 bore, which provides 3927 N of push force at 0.5 MPa. If a lower force and a more compact body are acceptable, the SC63 bore offers 1559 N at the same pressure. The CA rear clevis mount (part F-SC80CA) allows the cylinder to swing in a single plane, accommodating angular misalignment in the driven mechanism.
When replacing an existing cylinder, ensure a precise 5-point match: 80 mm bore, 75 mm stroke, PT3/8 port thread, rear single clevis mounting, and the absence of a magnetic piston. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; it is a direct replacement only for other AirTAC SC80 series or equivalent tie-rod cylinders matching these specifications.
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 SC80 Standard Cylinder SC80X75CA FAQ
At 0.5 MPa, the cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X75CA is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop under load. The adjustable air cushion only decelerates the piston at the stroke end to reduce impact; it is not a locking or holding brake. For load-holding safety, you must add an external rod lock or a pilot-operated check valve.
