About the Airtac SC100 Standard Cylinder SC100X155
The AirTAC SC100X155 is a double-acting tie-rod cylinder delivering a push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 155 mm stroke, this model features a 25 mm diameter piston rod, PT1/2 ports, and an adjustable pneumatic cushion of 29 mm at each end to decelerate the piston smoothly.
This cylinder has a body length A of 188 mm, giving a total extended length of approximately 343 mm. It operates on filtered air within a standard pressure range of 0.15-1.0 MPa and a temperature range of -20 to +70 °C using its default TPU seals. The SC100X155 is a basic configuration without a magnet, mounting accessories, or special seals, offering a cost-effective solution for straightforward linear push-pull applications.

Where the Airtac SC100 Standard Cylinder SC100X155 Is Used
Clamping & Fixturing
The 3927 N push force at 0.5 MPa makes the SC100X155 ideal for heavy-duty workholding, welding jigs, and assembly fixtures where a compact 155 mm stroke securely locks components in place.
Material Handling
Provides robust linear actuation for diverters, gates, and pushers on conveyor lines. The 25 mm rod and tie-rod construction offer rigidity for repetitive pushing tasks in distribution centers.
Press & Forming Assist
Suitable for light press-fit operations, bending assists, or stamping ejection. The adjustable cushion absorbs impact at the end of the 155 mm stroke, protecting tooling during high-cycle forming processes.
Is the Airtac SC100 Standard Cylinder SC100X155 the Right Cylinder?
Select the SC100X155 when your application requires approximately 4000 N of force at typical plant pressure. For lower force requirements around 2500 N, consider stepping down to the 80 mm bore SC80 series; for higher demands near 6100 N, the 125 mm bore SC125 series is the next step up. This model uses standard PT ports and comes without a built-in magnet.
For a drop-in replacement, match five key points: a 100 mm bore, a 155 mm stroke, PT1/2 port threads, a basic (no bracket) mounting configuration, and the absence of a magnet. This is a tie-rod cylinder with a shorter body length than an ISO 15552 profile, so it is not dimensionally interchangeable with ISO 15552 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 SC100 Standard Cylinder SC100X155 FAQ
At 0.5 MPa, the theoretical push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The maximum theoretical force at 1.0 MPa is 801 kgf.
No. The SC100X155 is a double-acting cylinder and does not hold its position when air pressure is exhausted or the directional valve is centered. The piston will drift or drop. If load holding is required, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
