About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-30
The AirTAC SAIJ100X35-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 5 to 35 mm usable travel window from its 35 mm nominal stroke. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers 3927 N of push force at 0.5 MPa. This adjustable design allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops.
The rear adjuster acts purely as a travel stop and works alongside the adjustable air cushions at both ends to decelerate the load, but it does not hold the load without live air pressure. For load-holding without live pressure, consider the SAIL or BSAI series. This model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-30 Is Used
Short-Stroke Clamping
Dial in the exact clamping end-stop for delicate or variable-thickness parts using the 5-35 mm travel window without repositioning the whole fixture.
Machine Changeover
Quickly adjust the retract distance during product size changes on a packaging line, using the rear stopper instead of swapping cylinders.
High-Force Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or stops into exact positions over short distances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-30 the Right Cylinder?
Choose this 100 mm bore when you need high force (3927 N push at 0.5 MPa) over a short, precisely adjustable travel window. If your application requires less force, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa. The adjustable stroke is ideal for product-size changeovers on a line, letting you dial in the exact end-stop rather than machining a custom fixed-stroke SAI cylinder.
Because the stroke is under 300 mm, side-load stress is manageable, though the robust 25 mm rod and M20x1.5 thread handle standard loads well. Remember that the rear adjuster is a stop, not a lock; if the machine loses air, the cylinder will not hold its position. This cylinder operates at speeds of 30-800 mm/s and is dimensionally interchangeable per ISO 15552.
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 SAIJ100BX35-30 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjuster screw lets you trim the effective travel back by up to 30 mm from the 35 mm nominal stroke, creating a 5 to 35 mm usable travel window for exact end-position tuning. The adjuster is a mechanical stop, not a lock, so it cannot hold the load without live air pressure.
