About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-75
The AirTAC SAIJ100X600-75 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 3927N push force at 0.5 MPa and features a 25mm stainless steel (SUS304) piston rod with M20x1.5 threading, making it highly resistant to corrosion and capable of handling greater side loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model features a 600mm nominal stroke paired with a 75mm adjustment range, creating a usable travel window of 525 to 600mm. This built-in rear stopper allows you to fine-tune the exact end position at commissioning without adding external physical stops. The PT G1/2 porting and variable air cushions at both ends ensure controlled deceleration across its 30-800mm/s speed range.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-75 Is Used
Product Changeovers
Dial in the exact 525-600mm retract position during format changeovers on packaging lines without physically swapping cylinders or adding external stopper blocks.
Variable End Stops
Adjust the stroke on the fly for conveyor sorting arms that need to accommodate different package sizes or divert distances at the machine commissioning stage.
Heavy-Duty Positioning
Leverage the 3927N push force to move heavy pallets or fixtures, using the rear adjuster to fine-tune the final resting position within a 75mm window.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-75 the Right Cylinder?
Choose this 100mm bore cylinder when an application requires substantial thrust (3927N push / 3681N pull at 0.5 MPa) alongside variable end-stop positioning. If your force requirements are lower, stepping down to an 80mm bore yields 2513N push force, whereas moving up to a 125mm bore provides 6136N. The adjustable stroke is ideal for machine setups that undergo frequent product changeovers, allowing the retract position to be dialed in on the fly rather than swapping out a fixed-stroke SAI cylinder.
When ordering, confirm the 600mm stroke, 75mm adjustment, PT G1/2 ports, SUS304 rod material, and the required mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 600mm, an external guide is recommended to prevent excessive rod deflection and side-loading. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, consider the SAIL or BSAI series instead.
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 SAIJ100BX600-75 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from 600mm down to 525mm. It allows precise end-position tuning at commissioning, but it is a stop, not a lock, and does not hold the load without live air pressure.
