About the Airtac SC100 Standard Cylinder SC100X45
The SC100X45 delivers a substantial 3927 N of push force at 0.5 MPa, making it a compact powerhouse for short-throw clamping and pressing tasks. Its 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth end-of-stroke deceleration in a tight 45 mm working stroke.
This double-acting tie-rod cylinder uses a 100 mm bore with PT1/2 ports and operates reliably on filtered air from 0.15 to 1.0 MPa. The body length A is 188 mm, giving a total extended length of approximately 233 mm, ideal for installations where space is limited but high force is non-negotiable.

Where the Airtac SC100 Standard Cylinder SC100X45 Is Used
Short-Stroke Clamping
Generates nearly 4000 N of force in a 45 mm stroke, perfect for fixturing and workpiece clamping where jaw travel is minimal but holding power is critical.
Press-Fit Assembly
Delivers controlled, high-force insertion for bearings, bushings, or pins. The adjustable cushion prevents impact damage to parts during rapid short-stroke cycling.
Diverter Gate Actuation
Quick 45 mm throw diverts heavy packages on conveyor lines. The 25 mm rod resists bending under the repetitive, high-force demands of material handling.
Is the Airtac SC100 Standard Cylinder SC100X45 the Right Cylinder?
For applications needing more force than an 80 mm bore (2513 N at 0.5 MPa), the SC100 series steps up to 3927 N. If your load is lighter, dropping to an 80 mm bore reduces air consumption. At a 45 mm stroke, side loading is rarely a concern, but always align the rod with the load axis to protect the bearing.
When replacing this cylinder, match five points: 100 mm bore, 45 mm stroke, PT port thread, basic (no bracket) mounting, and no magnet. This ensures the new unit drops into the same footprint and plumbing without modification.
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 SC100X45 FAQ
At 0.7 MPa operating pressure, the SC100X45 produces 5497 N of push force and 3681 N of pull force, based on the 100 mm bore and 25 mm rod diameter.
This specific SC100X45 code does not include the -S magnet option, so the piston does not have a built-in magnet. To use CMSG/DMSG sensors, order the SC100X45-S variant which adds a magnetic ring to the piston.
