About the Airtac SC100 Standard Cylinder SC100X840TC
The AirTAC SC100X840TC is a double-acting single-rod pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa. With an 840 mm stroke and a 25 mm diameter piston rod, this model is built for medium-to-long linear movements in industrial automation. The body length A measures 188 mm, and the total extended length reaches approximately 1028 mm.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (order code F-SC100TC), allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. Standard PT (Rc) ports are 1/2 inch, and the adjustable air cushion (29 mm length) decelerates the piston smoothly at stroke ends. Operating pressure ranges from 0.15 to 1.0 MPa with a speed of 30-800 mm/s.

Where the Airtac SC100 Standard Cylinder SC100X840TC Is Used
Material Handling Gates
The 840 mm stroke and pivoting trunnion mount operate diverter gates on wide conveyors, sorting packages or bulk materials with a powerful 3927 N push at standard line pressure.
Welding Fixture Clamping
Provides long-reach clamping in automotive or structural welding jigs. The TC mount allows the cylinder to swing clear for part loading and unloading between cycles.
Agricultural Equipment Actuation
Controls the tilt or lift of hoppers and chutes on farming machinery. The tie-rod construction and trunnion pivot handle dusty outdoor conditions reliably.
Is the Airtac SC100 Standard Cylinder SC100X840TC the Right Cylinder?
For applications requiring slightly less force, the 80 mm bore SC80 series provides 2513 N at 0.5 MPa. If more force is needed, the 125 mm bore offers 6136 N at the same pressure. At 840 mm of stroke, the unsupported rod length is significant; ensure side loads are minimal or use an external guide rail to prevent rod bending and premature bearing wear. The TC centre trunnion mount allows the cylinder body to pivot, absorbing misalignment in the plane of motion.
To ensure a correct replacement, match five key points: 100 mm bore, 840 mm stroke, 1/2 inch PT port thread, centre trunnion (TC) mounting accessory, and the absence of a built-in magnet. This model is a direct swap for another AirTAC SC100 tie-rod cylinder with identical 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 SC100 Standard Cylinder SC100X840TC FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100 is a double-acting cylinder and will drift or drop if pressure is exhausted. For load holding, you must add an external pilot-operated check valve or a mechanical rod lock.
