About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-10
The AirTAC SAIJ32X125-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 115-125 mm usable travel window, allowing you to dial back the 125 mm nominal stroke by up to 10 mm during commissioning without adding external stops. Delivering 402N of push force at 0.5 MPa, it fits light-duty tasks perfectly.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. It supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-10 Is Used
Machine Commissioning
Dial in the exact 115-125mm end-of-stroke position during setup to perfect a new assembly process without swapping physical hardware.
Product Changeover
Quickly adjust the retract stop by up to 10mm on a packaging line when running a slightly shorter product variant.
End-Stop Trimming
Fine-tune the final resting position of a small pneumatic press to account for mechanical wear over time.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-10 the Right Cylinder?
Select this 32mm bore when you need precise end-position tuning on the fly, stepping down from a 40mm bore (which yields 628N at 0.5 MPa) to save space. The rear adjuster acts strictly as a travel stop to fine-tune deceleration, not as a lock; it cannot hold a load without live air. For position holding without pressure, consider an external pilot-operated check valve or the SAIL series.
To match this ISO 15552 interchangeable cylinder, specify a 32mm bore, 125mm stroke, 10mm adjustment, PT G1/8 port, and your required mounting. Note that the 12mm rod and M10x1.25 thread handle moderate side loads, but always guide the rod externally to prevent premature wear.
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 Adjustable Cylinder SAIJ32 SAIJ32BX125-10 FAQ
It features a rear adjuster screw that lets you shorten the effective travel from 125mm down to 115mm. This creates a 10mm tuning window to set the exact retract position without using external stops.
At 0.5 MPa it provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at its maximum operating pressure of 0.9 MPa.
