About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-10S
The AirTAC SAIJ100X35-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a substantial 7068N of push force at 0.9 MPa, making it suited for heavy-duty positioning tasks. Equipped with a -S magnet, it supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.
This model provides a 25-35 mm usable travel window, allowing you to dial in the exact end position without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the carbon steel rod features an M20x1.5 thread for robust load attachment.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-10S Is Used
Heavy-Duty Clamping
Dial in the exact 25-35mm clamping travel on heavy fixtures, compensating for material thickness variations during product changeovers.
Machine Setup Tuning
Fine-tune the retract end position during initial commissioning without machining new stop blocks or disassembling the line.
Variable End Stops
Adjust the stroke endpoint by up to 10mm directly at the rear screw to accommodate minor size differences in automated assembly processes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-10S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (yielding 4523N push at 0.9 MPa) is insufficient for your clamping or lifting requirements. The 10mm rear adjustment is ideal for fine-tuning the end position during machine setup or product changeover, avoiding the need to physically swap a fixed-stroke SAI cylinder. Remember that the rear adjuster acts as a travel stop, not a lock; the SAIJ does not hold loads without live air, so for fail-safe holding, consider an external rod lock or the SAIL series.
For replacing an ISO 15552 cylinder, match the 100mm bore, 35mm nominal stroke, 10mm adjustment, PT tapered port, and the -S magnet option. 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 SAIJ100X35-10S FAQ
At 0.9 MPa, this 100mm bore cylinder provides 7068N of push force and 3681N of pull force. At 0.5 MPa, it delivers 3927N push and 3681N pull.
The rear adjuster screw lets you shorten the 35mm nominal stroke by up to 10mm, creating a 25-35mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
