About the Airtac SE125 Standard Cylinder SE125X95S
The AirTAC SE125X95S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. Operating at 0.5 MPa, it delivers a substantial 6136 N push force and 5734 N pull force, peaking at 8590 N push when supplied with 0.7 MPa. The 95 mm stroke is driven by a robust Ø32 mm piston rod with an M27x2 thread.
Built with a square extruded aluminum barrel that eliminates external tie rods, this unit resists corrosion and mounts flush against machine frames. The integrated -S magnet allows seamless tracking by CMSE reed and DMSE electronic sensors, while field-adjustable air cushions at both ends absorb hard kinetic impacts at the stroke limits.

Where the Airtac SE125 Standard Cylinder SE125X95S Is Used
Press Brake Tooling
Provides the 6136 N push force required to clamp heavy sheet metal backgauges and tooling arrays securely into position during press brake forming.
Injection Molding Ejector
Drives robust ejection plates inside injection molding machines, using its 95 mm stroke and Ø32 mm rod to push dense plastic parts clear of the mold cavity.
CNC Fixture Clamping
Locks large cast iron or steel automotive blocks into CNC machining centers, utilizing the built-in -S magnet to confirm clamp engagement via DMSE electronic sensors.
Is the Airtac SE125 Standard Cylinder SE125X95S the Right Cylinder?
Generating 1252 kgf of maximum push force at 1.0 MPa, this 125 mm bore cylinder is the largest standard size in the SE range. If your application requires less force, stepping down to the 80 mm bore yields 2513 N of push at 0.5 MPa, offering a lighter, faster 30-800 mm/s cycle speed compared to this model's 30-500 mm/s limit. Because the 95 mm stroke is below the 300 mm threshold, side-load bending moments on the rod bearing are minimized, though an external guide is still recommended for heavy off-center loads. Remember that the adjustable end cushions only decelerate the piston near stroke limits; they do not hold the load if air pressure drops. For position holding, explore a BSE rod lock variant. As a dimensionally interchangeable ISO 15552 component, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders, utilizing the standard PT1/2 port and standardized mounting interface.
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 SE125X95S FAQ
At 0.5 MPa, the SE125X95S generates 6136 N of push force and 5734 N of pull force. When supplied with 0.7 MPa, the push force increases to 8590 N. The maximum push force is 1252 kgf at 1.0 MPa, and the operational speed range is 30-500 mm/s.
Yes, it features a standardized ISO 15552 mounting interface, making it dimensionally interchangeable with other ISO 15552 profile cylinders. However, it cannot hold a load if air is lost; the adjustable air cushions only decelerate the piston near the stroke ends and act as a brake. For true position holding, a BSE rod lock variant is required.
