About the Airtac SC100 Standard Cylinder SC100X990
The AirTAC SC100X990 is a double-acting single-rod pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 990 mm stroke approaches the maximum standard length for the 100 mm bore, making it suitable for long-travel material handling or pressing operations where a 25 mm diameter rod provides robust column strength.
This tie-rod cylinder features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 188 mm, giving a total extended length of approximately 1178 mm. Ports are PT1/2 with an M20x1.5 rod thread, and the standard TPU seals operate reliably from -20 to +70 C.

Where the Airtac SC100 Standard Cylinder SC100X990 Is Used
Long-Stroke Material Transfer
The 990 mm stroke pushes or pulls heavy components between conveyor lines or workstations, using its 3927 N force at 0.5 MPa to move large fabricated parts reliably.
Heavy-Duty Clamping & Fixturing
Applies up to 7068 N of clamping force at 0.9 MPa for welding jigs or assembly fixtures, holding large workpieces securely during machining or fabrication.
Pallet & Container Handling
Operates gates, diverters, or push-off mechanisms in logistics systems, where the 25 mm rod and tie-rod construction withstand repetitive impact loads in dusty environments.
Is the Airtac SC100 Standard Cylinder SC100X990 the Right Cylinder?
Select the SC100 bore when your application needs around 3900 N of force at standard plant pressure; if you require roughly 6100 N, step up to the SC125 (6136 N push at 0.5 MPa). For a lighter, more compact solution, the SC80 provides 2513 N. At a 990 mm stroke, the extended rod is long—ensure the load is guided externally or use a guided cylinder if significant side forces are present, as a long unsupported rod is vulnerable to bending and bearing wear.
For direct replacement, match five points: 100 mm bore, 990 mm stroke, PT1/2 port thread, basic mount (no factory-fitted bracket), and no built-in magnet. This model uses the default TPU seal and PT threads, so confirm your existing cylinder matches these specifications exactly.
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 SC100X990 FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder, so mounting dimensions and body length A (188 mm) differ. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder with matching bore, stroke, PT1/2 ports, and basic mounting.
