About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX45-30S
The AirTAC SAIJ100X45-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and provides a usable travel window of 15-45 mm, letting you dial back the 45 mm nominal stroke by up to 30 mm during machine setup. This model includes a SUS304 stainless steel rod and a built-in magnet for position sensing.
The rear adjuster acts purely as a mechanical stop to set the exact end position, meaning it does not hold the load without live air pressure. For load-holding without continuous air, consider an external rod lock or the SAIL and BSAI series. This cylinder uses a PT G1/2 port and includes adjustable air cushions at both ends to manage deceleration. It is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX45-30S Is Used
Variable End-Stop Machining
Dial in the exact clamping depth on machining fixtures without machining custom spacers, trimming up to 30 mm off the 45 mm stroke during part changeovers.
Product Size Changeover
Quickly adapt assembly line stops to new product dimensions by adjusting the rear screw, utilizing the 15-45 mm travel window for flexible line setup.
Press Fit Tuning
Fine-tune the press-in depth of pins or bearings on the fly, leveraging the 3927N push force at 0.5 MPa while ensuring precise end-position control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX45-30S the Right Cylinder?
Select this 100 mm bore when an 80 mm bore (providing 2513N push at 0.5 MPa) is insufficient for your workpiece, but you need precise end-position tuning without swapping cylinders or adding external stops. The adjustable stroke is ideal for product changeovers where the exact end-of-stroke varies by up to 30 mm. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise positioning feedback.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 45 mm stroke, 30 mm adjustment, PT G1/2 port, and the required mounting subset. The SUS304 stainless steel rod offers superior corrosion resistance compared to standard carbon steel. Because the stroke is short at 45 mm, side-load stress is minimal, but always ensure the load is guided to prevent rod binding.
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 SAIJ100BX45-30S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927N of push force and 3681N of pull force. The 45 mm nominal stroke can be adjusted backward by up to 30 mm, providing an effective usable travel window of 15 to 45 mm.
No, the rear adjuster functions only as a travel stop to set the end position and does not act as a lock or brake. The cylinder cannot hold a load without live air pressure. For fail-safe load holding, use an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI series cylinders.
