About the Airtac SE125 Standard Cylinder SE125X460S
The AirTAC SE125X460S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a robust 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a completely flush exterior that resists corrosion and simplifies the mounting of adjacent machine components. Equipped with a built-in magnet (-S), this unit readily interfaces with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.
Designed for substantial load handling, this 125 mm bore actuator features a 32 mm piston rod and operates at speeds of 30-500 mm/s. The field-adjustable pneumatic cushioning at both ends allows technicians to manually fine-tune end-cap deceleration via a set screw, effectively softening hard mechanical stops during high-mass transfers. It is a true ISO 15552 / VDMA 24562 profile cylinder, ensuring strict dimensional interchangeability for seamless retrofits.

Where the Airtac SE125 Standard Cylinder SE125X460S Is Used
Automotive Press Die Clamping
Delivers 6136 N of push force at 0.5 MPa to securely hold heavy stamping dies in place during automated press cycles, utilizing the 460 mm stroke to clear the tooling area during load changes.
Heavy Machinery Assembly Press
Provides the necessary thrust for seating large industrial bearings into heavy machinery housings, where the adjustable end cushions absorb the shock of high-mass initial contact.
Pallet Diverting Arm
Actuates a heavy-duty pivoting arm to reroute loaded pallets weighing over a ton on a packaging line, relying on the built-in magnet to trigger DMSE electronic sensors for position feedback.
Is the Airtac SE125 Standard Cylinder SE125X460S the Right Cylinder?
Selecting this 125 mm bore actuator means commanding up to 1252 kgf of maximum push force at 1.0 MPa, making it the largest standard SE size available for highly demanding cycles. If your application does not require this immense output, stepping down to the 100 mm bore yields a 3927 N push at 0.5 MPa, which may offer faster cycle times and lower air consumption. Because this is the largest standard bore, there is no larger SE neighbour to step up to.
With a 460 mm stroke, the unsupported 32 mm rod is subject to bending forces under heavy side loads; utilizing an external guide rail is strongly recommended to prevent premature rod-bearing wear. Remember that the adjustable air cushion only decelerates the piston near the stroke ends and does not lock the load—if air pressure is lost, the actuator will drift, requiring an external pilot-operated check valve or a BSE rod lock for secure holding. This unit uses a PT1/2 port and shares standardized ISO 15552 mounting hardware.
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.
