About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-10S
The AirTAC SAIJ32X40-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 30-40mm, letting you trim the nominal 40mm stroke by up to 10mm during commissioning. This variant includes a SUS420J2 stainless steel rod and a magnet for position sensing.
The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. You can fine-tune the retract end-position without swapping the cylinder or adding external stops, while the PT tapered port and M10x1.25 rod thread ensure standard ISO 15552 connectivity.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-10S Is Used
Machine Setup & Changeover
Dial in the exact 30-40mm travel window during product line changeovers without disassembling the actuator or adding external shims.
Variable End-Stop Positioning
Fine-tune the retract position on small assembly fixtures where a fixed 40mm stroke would otherwise require manual mechanical adjustments.
Sensor-Ready Actuation
Leverage the integrated magnet and dual sensor grooves to mount DMSE electronic or CMSE reed switches for precise end-of-stroke confirmation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-10S the Right Cylinder?
Choose this 32mm bore when you need 402N of thrust at 0.5 MPa (or 563N at 0.7 MPa) and require exact end-position tuning on the fly. If your application requires higher force, stepping up to the 40mm bore yields 628N at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, avoiding the need to stock multiple fixed-stroke SAI cylinders.
This SAIJ32X40-10-S uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold a load without live air. For position holding without pressure, consider an external rod lock or AirTAC SAIL/BSAI cylinders.
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 SAIJ32AX40-10S FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 10mm. This creates a usable travel window of 30-40mm from the nominal 40mm stroke, enabling fine-tuning of the end position at commissioning without changing the cylinder.
At an operating pressure of 0.5 MPa, the SAIJ32X40-10-S provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
