About the Airtac SE125 Standard Cylinder SE125X82S
The AirTAC SE125X82S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a robust 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a highly corrosion-resistant body that mounts flush against machine frames to save valuable space. The integrated -S magnet enables seamless position detection using AirTAC CMSE reed or DMSE electronic sensors along the three standard sensor grooves.
Designed for demanding cycles, this 125 mm bore unit relies on field-adjustable air cushioning at both stroke ends to decelerate massive 1252 kgf kinetic loads smoothly. The generous 40 mm cushion length and rigid Ø32 mm hard-chrome rod absorb high side loads, while the standardized ISO 15552 mounting interface ensures direct dimensional interchangeability for seamless retrofits.

Where the Airtac SE125 Standard Cylinder SE125X82S Is Used
Hydraulic Press Tonnage
Drives the primary ram on small hydraulic press frames, utilizing the 6136 N push force to stamp or form light-gauge sheet metal components securely.
Injection Mold Ejection
Actuates heavy mold ejection plates in plastics facilities, where the rigid Ø32 mm rod and 40 mm adjustable cushion safely absorb high impact loads at stroke end.
Pallet Lift Gates
Raises and lowers heavy load-bearing pallet gates in automated distribution centers, relying on the no-tie-rod profile to prevent debris accumulation in dusty environments.
Is the Airtac SE125 Standard Cylinder SE125X82S the Right Cylinder?
Selecting the SE125X82S makes sense when your application requires up to 6136 N of push force at 0.5 MPa. If you need less force, stepping down to the 100 mm bore yields 3927 N push, but if you require maximum thrust, this 125 mm bore provides the highest available output in the SE range, peaking at 8590 N push at 0.7 MPa. Because this is a double-acting cylinder, it will drift if air pressure is lost or the valve is centered; for positive load holding without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve.
To replace an existing cylinder, match the 82 mm stroke, PT1/2 port, and the appropriate ISO 15552 mounting accessory. The built-in -S magnet is already present for CMSE or DMSE sensor integration. Although 82 mm is a relatively short stroke, the heavy 1252 kgf maximum load capacity means you should still verify rod-bearing bending moments and use an external guide to prevent premature seal wear.
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 SE125X82S FAQ
The SE125X82S provides 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 for this 125 mm bore cylinder is 30-500 mm/s.
Yes, the SE125X82S is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders by matching the PT1/2 port, 82 mm stroke, and standard mounting hardware. The built-in -S magnet also allows you to directly mount AirTAC CMSE or DMSE sensors without extra hardware.
