About the Airtac SE125 Standard Cylinder SE125BX200S
The AirTAC SE125BX200S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic applications. It generates a substantial 6136 N of push force at 0.5 MPa, scaling up to 8590 N at 0.7 MPa. Equipped with a SUS304 stainless steel rod, this variant is purpose-built for corrosive environments and washdown duty, resisting rust where standard carbon steel rods fail.
Unlike traditional tie-rod designs, its square extruded aluminum barrel offers a clean, flush-mounting exterior with integrated sensor grooves on three sides. The built-in magnet supports CMSE reed and DMSE electronic position switches, while the field-adjustable air cushioning at both ends allows you to fine-tune end-of-stroke deceleration to absorb high kinetic energy without relying on fixed rubber bumpers.

Where the Airtac SE125 Standard Cylinder SE125BX200S Is Used
Palletizer Clamping
Delivers 6136 N of push force at 0.5 MPa to securely grip heavy palletized goods, utilizing the SUS304 rod for washdown compatibility in food and beverage packing lines.
Heavy Gate Actuation
Drives large industrial safety gates or machinery doors across the 200mm stroke, relying on adjustable air cushions to soften the impact of massive moving masses.
Press Roll Nip Adjustment
Regulates high-force nip pressure on large converting presses, where the 125mm bore provides the necessary 8590 N thrust at 0.7 MPa and the stainless rod resists chemical splashes.
Is the Airtac SE125 Standard Cylinder SE125BX200S the Right Cylinder?
If your application requires slightly less force, stepping down to the 100mm bore yields 3927 N of push at 0.5 MPa, whereas no larger standard bore exists in this series, making the 125mm the maximum power option at 6136 N. For this 200mm stroke, the 32mm rod and M27x2 thread provide a robust interface, but long unsupported loads still necessitate an external guide to prevent rod-bearing bending. Remember that the adjustable cushion only decelerates the piston near stroke end; it cannot hold a load if air pressure drops. For position holding, consider a BSE rod lock. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement sharing standard 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.
Airtac SE125 Standard Cylinder SE125BX200S FAQ
The SE125BX200S delivers 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, with a maximum push force of 1252 kgf at 1.0 MPa. It features a PT1/2 port, a 32mm SUS304 rod, an M27x2 rod thread, and operates at speeds of 30-500 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 standards, serving as a drop-in replacement for other ISO 15552 profile cylinders using shared mounting accessories. However, it does not hold position unpowered; the adjustable air cushion only decelerates the piston near stroke end and is not a locking mechanism.
