About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10S
The AirTAC SAIJ125X95-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 6136N push and 5734N pull force at 0.5MPa, using a PT tapered G1/2 port. The built-in rear stopper allows you to trim the nominal 95mm stroke back by up to 10mm, creating an 85-95mm usable travel window for precise commissioning.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, which mount cleanly into the dual-side extruded barrel grooves. The 32mm carbon steel rod and M27x2 thread provide robust resistance to side loads, while the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) supports versatile ISO 15552 integration.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10S Is Used
Product Changeover Tuning
Dial in the 85-95mm travel window on packaging lines when switching product sizes, using the rear screw to set new end positions rapidly without changing the cylinder.
Machine Setup Calibration
Fine-tune the final end-of-stroke position during initial commissioning to absorb mechanical tolerances and achieve exact positioning without external shims.
Heavy Material Forming
Leverage the 6136N thrust at 0.5MPa for pressing or forming heavy assemblies, adjusting the stroke by up to 10mm to control the precise depth of the operation.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10S the Right Cylinder?
Select this 125mm bore when a smaller 100mm cylinder (offering 3927N push at 0.5MPa) lacks the power to move your load, but a larger 160mm bore is physically oversized. The 10mm adjustment range is ideal for dialing in exact end positions during product changeovers without swapping cylinders or adding external stops. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an SAIL or BSAI cylinder.
To match this ISO 15552 replacement exactly, verify the 95mm nominal stroke, 10mm adjustment code, PT G1/2 port, and the -S magnet option for sensor switching.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-10S FAQ
At 0.5MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. It can deliver up to 8590N push force at 0.7MPa.
The rear adjuster acts as an external stopper that lets you shorten the 95mm nominal stroke by up to 10mm, providing an 85-95mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
