About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-10
The AirTAC SAIJ100X35-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 25 to 35 mm, allowing you to dial back the 35 mm nominal stroke by up to 10 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles substantial workloads with precision.
This variant uses a SUS304 stainless steel rod (code B) for superior corrosion resistance. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-10 Is Used
Precision End-Stop Tuning
Dial in the exact retract position within a 25-35 mm window during machine commissioning without installing external physical stops.
Product Changeover
Quickly adapt the stroke length by up to 10 mm on a packaging line when handling slightly different product sizes.
Heavy-Duty Clamping
Leverage the 3927 N push force at 0.5 MPa to secure heavy workpieces while fine-tuning the clamping depth precisely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-10 the Right Cylinder?
Choose this 100 mm bore when a 63 mm neighbor (offering 1559 N push at 0.5 MPa) lacks the required thrust. The adjustable stroke is ideal for machine setups requiring exact end-position tuning without swapping cylinders or adding external stops. Since the stroke is under 300 mm, side-load stress is minimal, though an external guide is still recommended for heavy lateral forces.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 35 mm stroke, 10 mm adjustment, G1/2 port, PT thread, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting. Note that this unit lacks a magnet (-S), so CMSE reed or DMSE electronic sensors cannot be used for position detection.
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 SAIJ100BX35-10 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 35 mm nominal stroke by up to 10 mm. This creates a usable travel window of 25 to 35 mm for fine-tuning end positions.
