About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-30
The AirTAC SAIJ100X600-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 5497 N of push force at 0.7 MPa. It features a SUS304 stainless steel rod and PT tapered ports. The integrated rear stopper allows you to trim the effective travel, creating a precise 570 to 600 mm usable window without changing the physical cylinder length.
This 100 mm bore actuator utilizes an extruded aluminum barrel with sensor grooves on both sides, operating at speeds of 30-800 mm/s. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-30 Is Used
Machine Changeover
Dial in the 570-600 mm travel window during product size changes without physically replacing the actuator or adding external shims.
Variable End-Positioning
Fine-tune the retract end-stop during commissioning to achieve exact positioning for critical pressing or forming tasks.
Adjustable Diverting
Accommodate varying package sizes on a conveyor line by adjusting the stroke rearward by up to 30 mm on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-30 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 3518 N push at 0.7 MPa) cannot meet your thrust requirements. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, preventing the need to swap out a fixed-stroke SAI cylinder. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 600 mm stroke, 30 mm adjustment, PT ports, and SUS304 rod material.
Because this model features a 600 mm stroke, the 25 mm rod diameter should still be paired with an external guide to prevent excessive side-loading on the piston. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ100BX600-30 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the nominal 600 mm stroke by up to 30 mm. This creates a usable travel window of 570 to 600 mm. The adjuster only sets the end position and does not lock the load without live air pressure.
At an operating pressure of 0.7 MPa, the SAIJ100X600-30 provides 5497 N of push force and 5146 N of pull force. At 0.5 MPa, the push force is 3927 N.
