About the Airtac SC100 Standard Cylinder SC100X250CB
The SC100X250CB is a 100 mm bore, 250 mm stroke double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa. This genuine AirTAC tie-rod cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 port connections, making it a robust actuator for medium-to-heavy linear motion tasks.
The rear double clevis (CB) mounting, supplied as accessory F-SC100CB, allows the cylinder body to pivot during operation, accommodating angular misalignment in swinging or articulating linkages. With a 29 mm adjustable air cushion at each end, the SC100X250CB decelerates the piston smoothly, reducing end-of-stroke impact and noise in high-cycle applications.

Where the Airtac SC100 Standard Cylinder SC100X250CB Is Used
Agricultural Equipment Actuation
The 3927 N push force at 0.5 MPa and rear clevis pivot mount suit heavy-duty movements on harvesters, balers, or tillage implements where the cylinder must swing through an arc.
Material Handling Diverters
With a 250 mm stroke and adjustable cushioning, this cylinder reliably shifts diverters or gates on conveyor lines, handling the impact of redirecting bulk materials or packages.
Press and Clamp Systems
Delivering up to 7068 N at 0.9 MPa, the SC100X250CB provides ample clamping force for woodworking presses, welding fixtures, or assembly jigs where a pivoting cylinder body simplifies mounting.
Is the Airtac SC100 Standard Cylinder SC100X250CB the Right Cylinder?
For applications needing more force, stepping up to the 125 mm bore SC125 series provides 6136 N at 0.5 MPa, while the 80 mm bore SC80 offers 2513 N if a smaller, lighter unit is preferred. At a 250 mm stroke, the 25 mm rod is well-supported within the standard range, but any significant side load should be managed with an external linear guide to prevent rod bearing wear.
When replacing an existing cylinder, match five key points: 100 mm bore, 250 mm stroke, PT1/2 port thread, CB rear double clevis mounting, and the standard TPU seal. This model does not include a magnet, so if sensor-based position feedback is required, select the -S magnet variant and compatible CMSG/DMSG sensors.
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 SC100X250CB FAQ
At 0.7 MPa operating pressure, the 100 mm bore generates 5497 N of push force on the piston. The pull force on the retract stroke is 3681 N, accounting for the 25 mm rod area. These values are based on the official AirTAC SC series thrust table.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length A (188 mm for the SC100) differ. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder matching the bore, stroke, PT1/2 ports, and CB rear double clevis mount.
