About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X150-10S
The AirTAC SAIJ125X150-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 140 to 150 mm, letting you dial in the exact retract end position during commissioning without swapping hardware. As a 125 mm bore unit, it delivers substantial thrust, pushing 6136 N and pulling 5734 N at 0.5 MPa.
This variant includes a standard magnet for CMSE reed and DMSE electronic sensors, utilizing the dual-side sensor grooves on the extruded aluminum barrel. The piston rod is carbon steel with an M27x2 thread, and the fluid porting is PT tapered G1/2. It operates at speeds of 30-500 mm/s and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X150-10S Is Used
Machine Setup Tuning
Dial in the exact 140-150 mm retract position during commissioning to perfect a pressing operation without adding external stopper blocks.
Product Changeover
Quickly accommodate a slightly shorter material thickness on a production line by trimming the stroke back up to 10 mm.
Heavy Clamping
Leverage the 6136 N push force at 0.5 MPa to secure heavy workpieces while precisely controlling the clamp contact point.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X150-10S the Right Cylinder?
Choose this 125 mm bore when an 80 mm bore is insufficient (an 80 mm yields 2268 N pull at 0.5 MPa) but a 160 mm bore is excessive (pulling 9425 N at 0.5 MPa). The 10 mm adjustment window is ideal for fine-tuning end stops during machine setup or product changeover, whereas a fixed SAI cylinder locks you into one exact dimension.
To match this ISO 15552 replacement exactly, specify: 125 mm bore, 150 mm stroke, 10 mm adjust, PT G1/2 port, the required mounting bracket, and the -S magnet. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI series cylinder.
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 SAIJ125X150-10S FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
The rear adjuster screw lets you shorten the effective stroke from the nominal 150 mm down to 140 mm. This stopper fine-tunes the end position but does not lock or hold the load without continuous air pressure.
