About the Airtac SC80 Standard Cylinder SC80X90TC
The SC80X90TC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). With an 80 mm bore and a 90 mm stroke, this model is configured with a centre trunnion mount, making it ideal for applications where the cylinder body needs to pivot during operation.
This tie-rod cylinder uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The total extended body length is approximately 272 mm, based on a 182 mm base body length plus the 90 mm stroke. It features an adjustable pneumatic cushion (28 mm length) to decelerate the piston smoothly at end-of-stroke.

Where the Airtac SC80 Standard Cylinder SC80X90TC Is Used
Pivoting Conveyor Gates
The centre trunnion mount allows this 80mm bore cylinder to pivot, making it perfect for actuating diverter gates on conveyor systems where the cylinder body must swing through an arc.
Clamping & Fixturing
With 2513 N of force at standard shop air, the SC80X90TC provides robust, repeatable clamping for welding fixtures or assembly jigs, especially where the mount needs to self-align.
Agricultural Machinery
Ideal for heavy-duty agricultural equipment like bale handlers or chute controls, the trunnion mount absorbs misalignment and the TPU seals perform reliably in dusty, outdoor conditions.
Is the Airtac SC80 Standard Cylinder SC80X90TC the Right Cylinder?
Choose the SC80X90TC when your application requires a pivoting motion, as the TC centre trunnion mount (supplied with the TCM1 bracket, part code F-SC80TC) allows the cylinder to swing. If a fixed linear mount is needed, consider the basic or LB foot-mounted variants. For higher force requirements, stepping up to the SC100 bore provides 3927 N at 0.5 MPa; for a lighter, more compact solution, the SC63 bore delivers 1559 N.
To ensure a correct replacement, match five key points: bore (80 mm), stroke (90 mm), port thread (PT), mounting accessory (TC centre trunnion), and magnet option (none on this model). For strokes of 300 mm or more, an external guide is recommended to protect the rod from side-load bending, though at 90 mm this is typically not a concern.
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 SC80X90TC FAQ
At the standard operating pressure of 0.5 MPa, this double-acting cylinder produces 2513 N extending and 2268 N retracting. The maximum force at 0.9 MPa is 4523 N push.
No, the AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement for another AirTAC SC80 tie-rod cylinder with matching stroke, PT ports, and TC mount.
