About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-40
The AirTAC SAIJ125X60-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 6136N of thrust at 0.5 MPa. With a 60mm nominal stroke and a 40mm adjustment range, it provides a usable travel window of 20-60mm. This allows precise end-position tuning during commissioning without adding external stops.
This SKU features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads. It includes adjustable air cushions at both ends and operates at speeds up to 500mm/s. The extruded aluminum barrel integrates sensor grooves on both sides for direct mounting of CMSE and DMSE switches.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-40 Is Used
Variable End-Stop Clamping
Dial in the exact 20-60mm clamping depth for parts of varying widths without physically swapping out the cylinder.
Machine Changeover Setup
Quickly fine-tune the retract end-position during line changeovers to accommodate new product dimensions.
Heavy-Duty Positioning
Leverage the 6136N thrust capacity to move heavy pallets while trimming the stroke back up to 40mm for precise stops.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-40 the Right Cylinder?
Choose this 125mm bore when an 80mm bore (2513N push at 0.5MPa) lacks thrust, but a 160mm bore (10053N) is excessive. The adjustable 20-60mm travel window is ideal for product changeovers requiring variable end-stops. Unlike a fixed SAI cylinder, this model fine-tunes the retract position mechanically. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
The rear adjuster acts solely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. Dimensionally interchangeable per ISO 15552, this cylinder uses a PT port, lacks a magnet, and has an adjustment code of 40mm.
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 SAIJ125AX60-40 FAQ
It features a rear adjusting screw that lets you mechanically shorten the effective stroke by up to 40mm. This creates a usable travel window of 20-60mm, allowing you to set the exact retract end-position without adding external stops.
At an operating pressure of 0.5 MPa, the SAIJ125X60-40 delivers a push force of 6136N and a pull force of 5734N. It can achieve a maximum push force of 1251 kgf at 1.0 MPa.
