About the Airtac SE125 Standard Cylinder SE125X195S
The AirTAC SE125X195S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a robust 6136 N push force at 0.5 MPa, leveraging a 125 mm bore and a 195 mm stroke to power demanding industrial equipment. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant profile that mounts flush against machine frames.
This model includes a built-in magnet (-S) for non-contact position sensing via AirTAC CMSE reed or DMSE electronic switches. To survive high-kinetic-energy end-of-stroke impacts, it features field-adjustable air cushioning at both ends, allowing technicians to fine-tune deceleration and eliminate hard mechanical stops.

Where the Airtac SE125 Standard Cylinder SE125X195S Is Used
Press Brake Tooling
Provides the 8590 N push force at 0.7 MPa required to actuate heavy press brakes and stamping dies, utilizing the adjustable cushion to soften high-speed impacts.
Pallet Dispenser Ejection
Drives robust ejection arms in automated palletizing lines, using the 195 mm stroke to push heavy loads reliably off conveyor rollers.
Injection Mold Clamping
Secures large injection mold halves, relying on the 1252 kgf maximum thrust and the rigid extruded aluminum barrel to maintain alignment under high pressure.
Is the Airtac SE125 Standard Cylinder SE125X195S the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this 125 mm bore cylinder is suited for high-force operations. If your application requires less energy, the 100 mm bore model offers 3927 N of push force at 0.5 MPa; conversely, if you need maximum power, the 125 mm is the largest standard SE size available, reaching 1252 kgf at 1.0 MPa. Remember that a standard SE cylinder will drift and cannot hold a load if air pressure drops—use a BSE rod lock variant for secure positioning.
For a 195 mm stroke, the substantial 32 mm rod and M27x2 thread handle significant side loads, but any extended, unsupported piston rod is prone to bending under lateral stress. Always pair this cylinder with an external guide rail to prevent rod-bearing damage and ensure smooth linear movement. Being dimensionally interchangeable per ISO 15552, it serves as a direct drop-in replacement for other ISO 15552 cylinders, sharing standard mounting hardware and PT1/2 ports.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X195S FAQ
