About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190SCB
The SC125X190SCB is a large-bore, double-acting tie-rod cylinder delivering a substantial 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 190 mm stroke and a robust 32 mm piston rod, it is built for heavy linear handling tasks where pivoting alignment is required.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear double clevis mount (-CB suffix, accessory F-SC125CB) that allows the cylinder body to pivot on a fork. The adjustable air cushion (28 mm length) decelerates the piston smoothly, and the PT1/2 port thread ensures straightforward pneumatic connections.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190SCB Is Used
Heavy Machinery Positioning
Pivoting gate or chute control on agricultural equipment, using the rear clevis to accommodate the arcing motion of the mechanism.
Wastewater Valve Actuation
Operating large butterfly or gate valves in treatment plants, where the 11045 N max force provides reliable shut-off against fluid pressure.
Pallet Transfer Systems
Pushing heavy pallets onto a conveyor lift, with the clevis mount allowing the cylinder to self-align and avoid binding under load.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190SCB the Right Cylinder?
Select the SC125 when your application needs force in the 6136 N range at 0.5 MPa. If you can work with 3927 N, stepping down to a 100 mm bore saves space and air consumption. For a 190 mm stroke on a 32 mm rod, side-load forces must be managed carefully—use an external guide rail or linear bearing to protect the rod bearing from bending moments.
For replacement, match five points: 125 mm bore, 190 mm stroke, PT port thread, the -S magnet option for sensor compatibility, and the CB rear double clevis mounting. This is an ISO 6430 class tie-rod cylinder, shorter than an ISO 15552 profile, so it is not a drop-in replacement for that standard.
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 SC125X190SCB FAQ
At 0.5 MPa (5 bar), 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 reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. As a standard double-acting pneumatic cylinder, it will drift or drop if pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at end-of-stroke; it is not a locking or holding brake. An external rod lock or pilot-operated check valve is required for position holding.
