About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-30
The AirTAC SAIJ100X200-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 200 mm nominal stroke by up to 30 mm. This yields a usable travel window of 170-200 mm, providing exact end-position tuning at commissioning without swapping hardware. It delivers robust thrust, pushing 5497 N at 0.7 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a travel stop and does not hold the load without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-30 Is Used
Machine Setup Changeover
Fine-tune the 170-200 mm end-stop during product line changeovers to accommodate varying package sizes without bolting on external physical stops.
Variable End-Stop Positioning
Dial in the exact retract distance during initial commissioning to perfectly time the 5497 N push force against varying workpiece heights.
Heavy-Duty Forming Press
Leverage the robust 100 mm bore and SUS304 stainless steel rod for high-side-load forming applications requiring precise stroke limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-30 the Right Cylinder?
Choose this 100 mm bore when a 63 mm cylinder (2182 N push at 0.7 MPa) is insufficient, but a 125 mm bore is oversized. The adjustable 170-200 mm window is ideal for product changeovers, letting you fine-tune the retract position without adding external stops. Because the stroke is 200 mm, side-load risks are moderate, but always guide the load externally for optimal longevity.
To match this ISO 15552 interchangeable cylinder, specify: 100 mm bore, 200 mm stroke, 30 mm adjustment, PT G1/2 port, and no magnet. Remember that the rear screw is a stop, not a lock; for load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX200-30 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 5148 N of pull force. It can reach a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 200 mm nominal stroke by up to 30 mm, creating a 170-200 mm travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
