About the Airtac SE125 Standard Cylinder SE125X1500
The AirTAC SE125X1500 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic applications. Operating at 0.5 MPa, it delivers a substantial 6136 N push force and 5734 N pull force, scaling to a maximum of 1252 kgf at 1.0 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact footprint that resists corrosion and mounts flush against machine frames.
This 125 mm bore unit features a PT1/2 port, a robust Ø32 mm piston rod with an M27x2 thread, and a 40 mm cushion length. It lacks a built-in position sensor magnet on this specific SKU, but the field-adjustable air cushions at both ends allow technicians to fine-tune end-of-stroke deceleration, protecting machinery from impact shocks during high-speed 30-500 mm/s operations.

Where the Airtac SE125 Standard Cylinder SE125X1500 Is Used
Automotive Body Welding
Provides the 6136 N push at 0.5 MPa required to clamp heavy vehicle chassis panels securely in robotic spot-welding fixtures over a 1500 mm span.
Injection Mould Ejection
Drives large plastic injection mould bases, utilizing the 1252 kgf maximum force to reliably strip bulky automotive interior panels from deep-cavity dies.
Palletizer Strapping
Actuates heavy-duty strapping and sealing heads over wide conveyor lanes, using the 1500 mm stroke to accommodate oversized industrial pallet loads.
Is the Airtac SE125 Standard Cylinder SE125X1500 the Right Cylinder?
Generating 6136 N of push force at 0.5 MPa, this 125 mm bore cylinder is the largest standard size in the SE series. If your application requires less force, stepping down to the 100 mm bore yields 3927 N of push, while this SE125X1500 remains the ceiling option for the most demanding loads. As a dimensionally interchangeable ISO 15552 component, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders, matching the 125 mm bore, 1500 mm stroke, PT1/2 port, and standard mounting accessories.
Because this model utilizes a 1500 mm stroke, the unsupported mass of the piston rod introduces a risk of rod-bearing bending under side loads. For any heavy push or pull extending over this distance, incorporating an external guide rail is strongly recommended to prevent premature seal wear. Additionally, the field-adjustable air cushion decelerates the piston near stroke end but does not lock or hold the load if air pressure is lost; for position holding, an external pilot-operated check valve or a BSE rod lock variant is required.
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 SE125X1500 FAQ
The SE125X1500 generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N, and the absolute maximum push force is 1252 kgf when operated at the maximum 1.0 MPa pressure.
No, the SE125X1500 is a double-acting cylinder and the adjustable air cushions only decelerate the piston near stroke end; they do not act as a mechanical brake. If the application must hold a vertical load without live air pressure, you must use a BSE series rod lock cylinder or an external pilot-operated check valve.
