About the Airtac SE125 Standard Cylinder SE125X600SFTC
The AirTAC SE125X600S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a substantial 6136 N push force at 0.5 MPa. Its extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies bracket alignment. The integrated -S magnet enables seamless position tracking with AirTAC CMSE reed or DMSE electronic sensors.
Equipped with a 600 mm stroke and an FTC center trunnion mounting accessory, this unit handles heavy linear transfer tasks. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when moving massive payloads at speeds up to 30-500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X600SFTC Is Used
Automotive Body Panel Press
Provides the 8590 N push force at 0.7 MPa required to lift and index heavy sheet metal stampings between robotic welding stations.
Palletizer Strapping Module
Utilizes the 600 mm stroke to extend across a wide conveyor, positioning heavy timber pallets for automated banding equipment.
Heavy-Duty Metal Straightener
Leverages the FTC trunnion mount to accommodate pivot articulation while applying 1252 kgf max force to flatten thick steel billets.
Is the Airtac SE125 Standard Cylinder SE125X600SFTC the Right Cylinder?
When sizing this 125 mm bore, evaluate your thrust margins: stepping down to the 100 mm bore drops the 0.5 MPa push to 3927 N, while the 125 mm bore is the largest standard size available, offering a maximum 1252 kgf at 1.0 MPa. Because this 600 mm stroke is non-standard and exceeds the 500 mm standard threshold for this bore, it is made-to-order and requires careful alignment. The FTC trunnion pivot minimizes angular rod stress, but an external guide rail is strongly recommended to prevent rod-bearing bending under heavy lateral loads.
For retrofits, the standardized ISO 15552 footprint guarantees dimensional interchangeability with other ISO 15552 profile cylinders, allowing you to reuse existing PT1/2 port plumbing and mounting hardware without machining. Note that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking mechanism, so a BSE rod lock is required if the load must be held during air loss.
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 SE125X600SFTC FAQ
This 125 mm bore cylinder 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, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operating speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable with any standard ISO 15552 profile cylinder, sharing identical mounting and PT1/2 port dimensions. The built-in -S magnet is designed specifically for flush mounting with AirTAC CMSE reed switches and DMSE electronic sensors in the three sensor grooves.
