About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-40S
The AirTAC SAIJ100X600-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 5497N push force at 0.7 MPa, utilizing a 25mm piston rod and G1/2 ports. The integrated -40mm adjustment mechanism allows you to fine-tune the effective travel anywhere within a 560-600mm window. This eliminates the need to physically swap cylinders or bolt on external stops during machine commissioning or product changeovers.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some standard models.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-40S Is Used
Variable End-Stop Tuning
Dial in the exact retraction point within the 560-600mm range during setup, perfect for accommodating slight mechanical variations without machining new hard stops.
Product Size Changeover
Quickly adjust the stroke by up to 40mm when switching a production line to handle a different pallet or product size, minimizing downtime.
Heavy Material Handling
Leverage the 5497N push force at 0.7 MPa to move heavy loads reliably while using the rear adjuster to fine-tune the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-40S the Right Cylinder?
Choose this 100mm bore when you need substantial thrust, such as the 3927N push force at 0.5 MPa, stepping up from a 63mm bore that provides 1559N. The adjustable stroke is perfect for applications requiring variable end-stops, acting as a physical stopper rather than a locking device. It cannot hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 100mm bore, 600mm stroke, PT tapered port threads, and the -S magnet requirement.
Because this model features a 600mm stroke, the extended travel increases the risk of side-loading. Despite the sturdy 25mm rod and M20x1.5 rod thread, an external guide should be used to prevent binding and premature seal wear over long distances.
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 SAIJ100 Adjustable Cylinder SAIJ100BX600-40S FAQ
At 0.5 MPa, the push force is 3927N and the pull force is 3681N. At 0.7 MPa, the push force increases to 5497N. The maximum theoretical push force at 1.0 MPa is 801 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 600mm stroke by up to 40mm, providing a usable travel window of 560-600mm. It only sets the end position and does not lock the load without live air pressure.
