About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-30S
The AirTAC SAIJ40X60-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 628N push force at 0.5 MPa and features a 30-60mm usable travel window, allowing you to trim the 60mm nominal stroke by up to 30mm during commissioning. This built-in adjustability eliminates the need to swap cylinders or add external stops when fine-tuning end positions.
Configured with a SUS304 stainless steel rod (code B) and a PT tapered port, this 40mm bore unit is ready for position sensing. The -S magnet integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-30S Is Used
Stroke Calibration
Dial in the exact 30 to 60mm travel distance during machine commissioning to perfect part seating without replacing hardware.
Product Changeover
Quickly adjust the retract end-stop on a packaging line to accommodate varying package sizes on the fly.
Sensor Positioning
Leverage the -S magnet and dual sensor grooves to set precise DMSE electronic switch trip points along the adjusted path.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-30S the Right Cylinder?
Choose this adjustable-stroke cylinder when your setup requires precise end-position tuning without mechanical rework, contrasting with a fixed-stroke SAI model. If your application demands less force, stepping down to a 32mm bore yields 402N of push force at 0.5 MPa; stepping up to a 50mm bore provides 982N. To replicate this ISO 15552 interchangeable cylinder, match the 40mm bore, 60mm stroke, 30mm adjustment, PT port, SUS304 rod, and -S magnet.
Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the rear screw stopper only decelerates the stroke and is not a lock, use a SAIL or BSAI cylinder if you need true load-holding without continuous air pressure.
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 SAIJ40 Adjustable Cylinder SAIJ40BX60-30S FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. It can reach a maximum push force of 1130N at 0.7 MPa.
The rear adjuster screw lets you shorten the 60mm nominal stroke by up to 30mm, creating a 30-60mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load.
