About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1500
The SC125X1500 is a heavy-duty double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 32 mm diameter piston rod and a 28 mm adjustable air cushion, this tie-rod cylinder is built for demanding linear applications requiring a full 1500 mm stroke.
This model belongs to the ISO 6430 class of big-bore cylinders, featuring a PT1/2 port and an M27x2 rod thread. The body length A is 203 mm, resulting in a total extended length of approximately 1703 mm. Its robust construction makes it suitable for heavy lifting, pressing, and material handling tasks where substantial force is essential.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1500 Is Used
Heavy Pallet Lifting
Provides the high force needed to lift and stack heavy pallets in automated warehouses, utilizing its full 1500 mm stroke for vertical movement.
Log Sorting Pusher
Acts as a powerful diverter in sawmill lines, pushing large timber logs onto different conveyor paths with 11045 N of force.
Industrial Compactor
Drives the compression plate in waste or recycling compactors, delivering consistent high-force strokes to reduce material volume.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1500 the Right Cylinder?
Select the SC125X1500 when your application demands force in the 6000-11000 N range. If your load requires less force, consider stepping down to the SC100 bore, which provides 3927 N at 0.5 MPa. For even higher force requirements, the SC160 bore offers 10053 N at the same pressure.
For this 1500 mm stroke, carefully evaluate side-loading conditions. Long, unsupported strokes on a 32 mm rod are susceptible to bending under lateral forces. To ensure reliable operation and prevent premature seal or bearing wear, use an external guide rail system or a guided cylinder variant to absorb side loads. When replacing this cylinder, match the 125 mm bore, 1500 mm stroke, PT1/2 port thread, basic mounting configuration, and the absence of a magnet sensor option.
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 SC125X1500 FAQ
The theoretical push force at 0.5 MPa is 6136 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The maximum theoretical force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. The SC125 is an ISO 6430 class cylinder. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with the same stroke, port thread, and mounting configuration.
