About the Airtac SE125 Standard Cylinder SE125X1000
The AirTAC SE125X1000 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a substantial 6136 N push force at 0.5 MPa and utilizes a PT1/2 port with a robust Ø32 mm piston rod. Because it is built to the ISO 15552 / VDMA 24562 standard, this cylinder is dimensionally interchangeable with other ISO 15552 cylinders, allowing you to retrofit existing machinery without altering mounting footprints.
This model features an extruded aluminum barrel without external tie rods, which streamlines the body profile and prevents internal corrosion buildup while allowing flush mounting on multiple sides. The field-adjustable air cushioning at both ends can be precisely tuned via a set screw to absorb the kinetic energy of a 1000 mm stroke, ensuring smooth deceleration rather than harsh mechanical impacts. Note that this specific SKU lacks a built-in magnet, so it cannot directly host CMSE or DMSE position sensors without modification.

Where the Airtac SE125 Standard Cylinder SE125X1000 Is Used
Automotive Tier-1 Press Ejection
Utilizing the 6136 N push force at 0.5 MPa, this cylinder reliably ejects heavy stamped chassis panels from a 1000-ton press bed over its 1000 mm stroke.
Heavy Machinery Assembly Line
Drives the main lifting platform to raise and lower 1250 kgf of drivetrain components during automated robotic bolting on a heavy equipment assembly line.
Palletizer Strapping Actuator
Actuates the heavy-duty strapping and sealing head over a 1000 mm vertical traverse to secure oversized steel pallets in a high-throughput logistics hub.
Is the Airtac SE125 Standard Cylinder SE125X1000 the Right Cylinder?
Selecting the SE125X1000 is appropriate when your application requires moving heavy loads over a long distance, demanding the maximum 1252 kgf available at 1.0 MPa. If you need slightly less force, stepping down to the 100 mm bore yields a 3927 N push at 0.5 MPa; conversely, the 125 mm is the largest standard SE bore available. Because this cylinder features a 1000 mm stroke, the unsupported length of the Ø32 mm rod under high side loads can induce rod-bearing bending—an external guide is strongly recommended to prevent premature seal wear.
Keep in mind that a standard SE cylinder cannot hold a load in place if air pressure is lost or the control valve is centered; the piston will drift. If your machinery requires mid-stroke position holding or fail-safe braking, you must integrate an external pilot-operated check valve or transition to the AirTAC BSE rod-lock variant. Furthermore, the adjustable end cushions only decelerate the piston near the stroke endpoints and do not act as a mechanical brake.
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 SE125X1000 FAQ
This 125 mm bore cylinder provides 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a maximum push of 1252 kgf at 1.0 MPa. Its operational speed range is 30-500 mm/s.
Yes. The SE125X1000 is a true ISO 15552 / VDMA 24562 profile cylinder, meaning its mounting dimensions and PT1/2 port locations are standardized for drop-in interchangeability with other ISO 15552 profile cylinders, simplifying retrofits.
