About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-100S
The AirTAC SAIJ100X850-100-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, enabling a usable travel window of 750-850 mm from its 850 mm nominal stroke. Equipped with a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. A carbon steel rod with an M20x1.5 thread provides a robust interface for high-load duties.
Delivering 7068 N of push force at 0.9 MPa, this 100 mm bore unit handles heavy positioning tasks. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end during commissioning; it does not lock the load without live air. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-100S Is Used
Machine Changeover
Dial in the retract end-stop by up to 100 mm during product size changes without swapping the cylinder or adding external stopper blocks.
Material Handling
Provides 7068 N of push force at 0.9 MPa to index heavy pallets, with a 750-850 mm travel window for fine-tuning the discharge position.
Heavy Assembly Press
Uses the M20x1.5 carbon steel rod to drive heavy components, relying on the rear adjuster to set precise end-of-stroke contact depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-100S the Right Cylinder?
Select this adjustable-stroke model when you need to dial in a precise retract position on the fly, avoiding the need to swap cylinders or bolt on external stops during product changeovers. If your application requires less force, stepping down to an 80 mm bore yields 4523 N of push force at 0.9 MPa, whereas a 125 mm bore offers 11045 N for heavier loads.
When matching ISO 15552 replacements, verify the 100 mm bore, 850 mm stroke, 100 mm adjustment range, PT tapered port, and the -S magnet option. Mounting choices span Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 850 mm stroke is long and unsupported, an external guide is recommended to manage side loads and prevent rod binding.
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 SAIJ100X850-100S FAQ
A rear external screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 100 mm. This creates a 750-850 mm usable travel window for fine-tuning the retract end position at commissioning.
At 0.9 MPa, the SAIJ100X850-100-S provides 7068 N of push force and 5497 N of pull force. It operates at speeds between 30-800 mm/s.
