About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190STC
The AirTAC SC125X190STC is a double-acting single-rod pneumatic cylinder delivering a robust 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 190 mm stroke is well within the 1500 mm standard range for this bore, making it a reliable workhorse for medium-travel linear actuation.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion pivot (TC mount with TCM1 bracket, order code F-SC125TC) that lets the cylinder swing through an arc. The 32 mm piston rod, PT1/2 ports, and 28 mm adjustable air cushion provide dependable deceleration without external shock absorbers.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190STC Is Used
Pallet & Case Handling
The 6136 N push force at 0.5 MPa easily transfers heavy pallets or cases across roller conveyors. The centre trunnion mount allows the cylinder to pivot as the load moves, reducing rod side-load.
Clamping & Forming Presses
Delivers up to 11045 N of clamping force at 0.9 MPa for holding workpieces during welding, gluing, or light forming. Magnetic piston sensors confirm clamp position before the cycle starts.
Grain Chute Diverters
The 190 mm stroke and pivoting TC mount suit grain or aggregate chute gates. The adjustable cushion softens the gate impact at end of travel, protecting the cylinder and structure.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X190STC the Right Cylinder?
Choose 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 load is lighter, stepping down to an SC100 bore saves space and air (3927 N at 0.5 MPa). For heavier demands, the SC160 bore jumps to 10053 N at 0.5 MPa. This 190 mm stroke is standard, but always confirm the rod bearing can handle any side load.
For a direct replacement, match five points: 125 mm bore, 190 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor feedback. The SC is a tie-rod cylinder—shorter than an ISO 15552 profile—so dimensional interchangeability is limited to another AirTAC SC of the same configuration.
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 SC125X190STC FAQ
At 0.5 MPa, push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X190STC means a magnet is built into the piston. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without extra brackets.
