About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150LB
The SC125X150LB is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa, rising to 11045 N at the maximum operating pressure of 0.9 MPa. With a 125 mm bore and 150 mm stroke, this ISO 6430 class tie-rod cylinder uses a 32 mm diameter piston rod and M27x2 rod thread for robust linear actuation.
This model is configured with an LB foot mount (F-SC125LB) for secure surface mounting, and features adjustable air cushioning with a 28 mm cushion length to decelerate the piston smoothly. The standard PT1/2 port and TPU seals suit a -20 to +70 °C operating range, making it a reliable workhorse for medium-speed industrial tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150LB Is Used
Heavy Material Handling
The 6136 N push force at 0.5 MPa makes this cylinder ideal for lifting, transferring, or positioning heavy components on assembly and conveyor lines.
Press & Clamping Fixtures
Delivering up to 11045 N at 0.9 MPa, the SC125X150LB provides the high clamping force needed for industrial presses, welding jigs, and machining fixtures.
Gate & Damper Actuation
The foot-mounted design and 32 mm rod diameter offer the rigidity needed to operate heavy sliding gates, hopper doors, and air dampers in processing plants.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150LB the Right Cylinder?
Select the SC125 bore when your application needs between 6136 N (push at 0.5 MPa) and 11045 N (push at 0.9 MPa). If your force requirement is lower, stepping down to the SC100 bore provides 3927 N at 0.5 MPa. For higher forces, the SC160 bore delivers 10053 N at 0.5 MPa. The 150 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
To ensure a correct replacement, match five key points: bore (125 mm), stroke (150 mm), port thread (PT), mounting accessory (LB foot mount), and magnet option (none on this model). For strokes of 300 mm or more, always consider an external guide or guided cylinder to protect the rod bearing from bending under side load.
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 SC125X150LB FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a standard ISO 15552 cylinder, so it is not dimensionally interchangeable. For a correct replacement, match the SC series specifically, verifying the 125 mm bore, 150 mm stroke, PT port thread, and LB foot mount.
