About the Airtac SE125 Standard Cylinder SE125BX75CA
The AirTAC SE125BX75CA is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty actuation. It generates 6136 N of push force at 0.5 MPa and features a 125 mm bore paired with a 75 mm stroke. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal mechanics.
This specific SKU utilizes a SUS304 stainless steel piston rod (material code B) tailored for corrosive environments and washdown processing lines. Although this configuration lacks a built-in position magnet, the barrel retains sensor grooves on three sides for future instrumentation. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration, softening hard impacts when moving substantial masses.

Where the Airtac SE125 Standard Cylinder SE125BX75CA Is Used
Heavy Press Stamping
Provides 6136 N of thrust at 0.5 MPa to drive large metal forming and stamping presses, utilizing the 75 mm stroke for rapid, high-impact cycles.
Washdown Food Processing
The SUS304 stainless rod withstands harsh chemical rinses in food and beverage facilities, actuating heavy hopper gates or sorting diverter arms.
Automotive Welding Fixtures
Employs the CA clevis to pivot massive welding clamp arms into position on automotive assembly lines, relying on 8590 N thrust at 0.7 MPa to hold components rigid.
Is the Airtac SE125 Standard Cylinder SE125BX75CA the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this 125 mm bore cylinder handles massive loads; if you need less force, stepping down to the 80 mm bore yields 2513 N, while this SE125BX75CA remains the largest standard option in the series. The CA single clevis mounting accessory supplied here accommodates pivoting articulation. Remember that the adjustable air cushion only decelerates the piston near stroke end—it is not a locking mechanism. If your pivoting load must maintain its position without live air pressure, integrate an external pilot-operated check valve or upgrade to a BSE rod lock variant.
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 SE125BX75CA FAQ
This 125 mm bore cylinder delivers 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a maximum push force of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
