About the Airtac SE125 Standard Cylinder SE125X450
The AirTAC SE125X450 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. Operating at 0.5 MPa, it generates a substantial 6136 N push force and 5734 N pull force, scaling to a maximum of 1252 kgf at 1.0 MPa. The 125 mm bore pairs with a robust Ø32 mm rod and M27x2 thread to handle high side loads, while the PT1/2 port ensures high flow rates for rapid actuation.
Unlike traditional tie-rod designs, this unit features a square extruded aluminum barrel that mounts flush and resists corrosion. The integrated sensor grooves on three sides of the body allow flexible positioning of CMSE or DMSE switches, though this specific SKU ships without the -S magnet. Furthermore, the field-adjustable air cushioning at both ends utilizes a 40 mm cushion length to smoothly decelerate heavy masses at speeds up to 30-500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X450 Is Used
Hydraulic Press Ejection
Ejecting heavy formed metal parts from a 200-ton hydraulic press requires the 6136 N push force available at 0.5 MPa, utilizing the 450 mm stroke to safely clear the die area.
Foundry Mold Transfer
Pushing large resin-bonded foundry molds onto a conveyor benefits from the 125 mm bore's 1252 kgf maximum force, while the field-adjustable cushioning absorbs the kinetic energy of the heavy mold at end-of-stroke.
Palletizer Stopper Gate
Acting as a heavy-duty stop gate at the end of a high-speed palletizing line, the robust Ø32 mm rod withstands pallet impacts, and the tie-rod-free extruded barrel resists dusty warehouse environments.
Is the Airtac SE125 Standard Cylinder SE125X450 the Right Cylinder?
When sizing this 125 mm bore model, consider stepping down to the 100 mm bore cylinder if your load requires less force, as it provides 3927 N of push at 0.5 MPa. Since 125 mm is the largest standard bore in the SE series, there is no larger step-up option available. Remember that a plain SE cylinder does not hold its position or load when air is lost or the valve is centered; the piston will drift. If your application requires dead-stop holding without live pressure, you must integrate an external rod lock or pilot-operated check valve.
With a 450 mm stroke, the unsupported rod length is significant. The M27x2 thread and Ø32 mm rod carry substantial side loads, but you should still use an external guide to prevent rod-bearing bending under heavy offset loads. For a drop-in retrofit, this cylinder is dimensionally interchangeable per ISO 15552, matching the exact mounting footprint and accessories of other ISO 15552 profile cylinders.
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.
