About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-30
The AirTAC SAIJ100X650-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 30 mm of end-position trimming. This yields a usable travel window of 620 to 650 mm, allowing precise machine setup without adding external stops. Operating at 0.5 MPa, it generates 3927 N of push force and 3681 N of pull force.
This unit incorporates a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. It utilizes a reduced mounting set comprising Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for position detection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-30 Is Used
Machine Setup & Changeover
Dial in the exact 620-650 mm end position during product size transitions without swapping out the entire cylinder or re-engineering external stop blocks.
Variable End-Stop Positioning
Ideal for diverter arms or reject mechanisms where the retract distance needs precise tuning to accommodate varying package sizes on a shared line.
High-Force Actuation
Leverages the 100 mm bore's 3927 N push force at 0.5 MPa to move heavy pallets or tooling, while the 30 mm adjuster absorbs mechanical tolerance variations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-30 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (providing 1559 N push force at 0.5 MPa) is insufficient to move your load, but a larger 125 mm bore is unnecessary. The 30 mm adjustment range is ideal for fine-tuning the retract end during commissioning or product changeovers, offering flexibility a fixed-stroke SAI cylinder cannot match. Keep in mind the rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for secure load-holding, consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI models.
Because the 650 mm stroke is substantial, an external guide is recommended to prevent excessive side loading on the SUS304 rod. To replace an ISO 15552 cylinder, match the 100 mm bore, 650 mm nominal stroke, 30 mm adjustment, PT port, and your required mounting style. The cylinder operates at speeds of 30-800 mm/s.
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 SAIJ100BX650-30 FAQ
At a standard operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This creates an adjustable travel window of 620 to 650 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
