About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100CA
The SC125X100CA is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa. Its 100 mm stroke is paired with a robust 32 mm diameter piston rod and a 28 mm adjustable air cushion for reliable end-of-stroke deceleration.
This model features a rear single clevis mount (CA) for pivoting applications, with the mounting accessory coded F-SC125CA. As a tie-rod cylinder, it offers a compact body length of 203 mm plus the stroke, making it shorter than an equivalent ISO 15552 profile cylinder.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100CA Is Used
Agricultural Equipment Actuation
Operates heavy pivot arms and gates on harvesters or tillage equipment, where the rear clevis mount allows the cylinder body to swing freely.
Heavy-Duty Clamping Fixtures
Applies up to 1.1 tonnes of clamping force in welding jigs and machining centers, holding large workpieces securely during fabrication.
Waste Compactor & Baler Drives
Drives the compression plate in recycling balers, providing the high force needed to compact cardboard, plastics, or metal scrap into dense bales.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100CA the Right Cylinder?
Choose the SC125 bore when your application requires a push force between 6136 N and 11045 N. For lower force needs, stepping down to the SC100 bore provides 3927 N at 0.5 MPa. For higher demands, the SC160 bore offers 10053 N at the same pressure. Ensure a perfect replacement by matching five key points: bore, stroke, port thread (PT), mounting accessory (CA rear clevis), and magnet option.
For this 100 mm stroke, the 32 mm rod is well-supported within the cylinder body for axial loads. If your application involves significant side loading, consider an external linear guide to protect the rod bearing and seals from premature wear.
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 AIRTAC SC125-160 Standard Cylinder SC125X100CA FAQ
At the standard operating pressure of 0.7 MPa, the push force is 8590 N and the pull force is 5734 N. The maximum theoretical push force at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder. It is not a drop-in replacement. It directly replaces another AirTAC SC125 cylinder with the same stroke, PT port, and CA rear clevis mount.
