About the Airtac SE125 Standard Cylinder SE125X170
The AirTAC SE125X170 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. Operating at 0.5 MPa, it provides a formidable 6136 N push force and 5734 N pull force, scaling to a maximum of 1252 kgf at 1.0 MPa. The extruded aluminum barrel omits external tie rods, yielding a smooth, corrosion-resistant exterior that mounts flush against machine frames without snagging.
This 125 mm bore unit features a Ø32 mm piston rod and a PT1/2 port. It lacks a built-in position magnet, meaning no CMSE or DMSE sensors can be fitted to this specific SKU. To absorb the high kinetic energy generated by moving large masses at speeds up to 500 mm/s, the cylinder incorporates field-adjustable air cushions at both ends, allowing technicians to dial in end-of-stroke deceleration and eliminate hard impact stress.

Where the Airtac SE125 Standard Cylinder SE125X170 Is Used
Hydraulic Press Ejection
Provides the 6136 N push force required to eject heavy forged metal components from a 170 mm stroke hydraulic press bed, utilizing the smooth profile barrel for flush press-frame mounting.
Injection Mold Clamping
Delivers up to 1252 kgf at 1.0 MPa to secure heavy injection mold tooling plates, relying on the field-adjustable cushions to soften the 170 mm stroke ends and protect expensive mold halves.
Structural Beam Straightening
Applies massive opposing thrust to deform and straighten thick structural steel beams, where the Ø32 mm rod handles the high compressive loads without buckling within the 170 mm travel.
Is the Airtac SE125 Standard Cylinder SE125X170 the Right Cylinder?
When sizing this 125 mm bore model, compare its 6136 N push force at 0.5 MPa against its neighbors to ensure you have the exact capacity required. Stepping down to the 100 mm bore yields 3927 N, which is often sufficient for lighter fixtures and saves space. If you need maximum thrust, this 125 mm bore is the largest standard option available in the SE series. Because this is a double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; applications requiring static holding must integrate an external rod lock like the BSE series or a pilot-operated check valve.
For a drop-in retrofit, this cylinder is dimensionally interchangeable per ISO 15552 standards, matching the 170 mm stroke, PT1/2 port, and standard mounting interface of equivalent profile cylinders. The 170 mm stroke is below the 300 mm threshold, so standard rod-bearing bending is minimal, but the sheer mass of the 32 mm rod still requires verifying your mounting hardware can handle the lateral inertia during reversal.
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 SE125X170 FAQ
The SE125X170 delivers 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, with an absolute maximum push of 1252 kgf at 1.0 MPa. The operating speed range for this 125 mm bore cylinder is 30-500 mm/s.
No, the SE125X170 is a standard double-acting cylinder and the piston will drift if air is lost or the valve is centered. The adjustable air cushions only decelerate the piston near the end of the stroke; they do not lock the load. For secure holding, use a BSE series rod lock cylinder or an external pilot-operated check valve.
