About the Airtac SE125 Standard Cylinder SE125BX1000S
The AirTAC SE125BX1000S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty linear motion. It delivers a substantial 6136 N push force at 0.5 MPa (8590 N at 0.7 MPa) and features a robust 125 mm bore paired with a 1000 mm stroke. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush in tight machinery spaces while maintaining the standardized ISO 15552 footprint.
This configuration incorporates a SUS304 stainless steel rod (code B) for superior resistance in washdown or corrosive settings, and includes a built-in magnet (code S) for non-contact position sensing with AirTAC CMSE reed or DMSE electronic switches. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard mechanical stops during high-speed 30-500 mm/s cycles.

Where the Airtac SE125 Standard Cylinder SE125BX1000S Is Used
Palletizer Case Pusher
Drives heavy pallet loads transversely at the end of packaging lines, utilizing the 6136 N push force to shift full cartons without faltering.
Metal Stamping Ejector
Clears heavy stamped metal blanks from hydraulic presses, relying on the SUS304 rod to withstand coolant splash and debris during 1000 mm extraction.
Automotive Body Lift
Elevates vehicle chassis subframes along a 1000 mm travel path, using the adjustable end cushions to soften the 500 mm/s end-stop impact safely.
Is the Airtac SE125 Standard Cylinder SE125BX1000S the Right Cylinder?
When sizing this 125 mm bore actuator, evaluate your force margins: stepping down to the 100 mm bore drops the 0.5 MPa push output to 3927 N, while no larger standard bore exists in this series, making the 125 mm the maximum thrust option at 6136 N. Because this unit carries a non-standard 1000 mm stroke, it is a made-to-order item. It requires a PT1/2 port, M27x2 rod thread, and standard ISO 15552 mounting accessories.
At 1000 mm of unsupported travel, the 32 mm rod is highly susceptible to side-load bending and bearing wear; an external guide rail is strongly recommended to prevent premature seal failure. Note that an SE cylinder relies on continuous air pressure to hold position—if pilot pressure drops, the piston drifts, so integrate a BSE rod lock for fail-safe load holding. The adjustable end cushions decelerate the mass but do not function as a mechanical brake.
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 SE125BX1000S FAQ
This 125 mm bore cylinder generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a maximum push of 1252 kgf at 1.0 MPa. The 1000 mm stroke is a non-standard made-to-order length exceeding the 1500 mm maximum standard stroke, operating at 30-500 mm/s.
Yes, the SE125BX1000S is dimensionally interchangeable with any ISO 15552 profile cylinder, sharing identical mounting interface and PT1/2 port spacing for drop-in retrofits. However, it does not hold loads unpowered; if air is lost, the piston drifts, requiring a BSE rod lock for fail-safe position holding.
