About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-10S
The AirTAC SAIJ100X90-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 80-90 mm from its 90 mm nominal stroke. Delivering 3927 N of push force at 0.5 MPa, it is designed for high-force tasks requiring exact end-position calibration. The integrated -S magnet enables direct mounting of CMSE reed and DMSE electronic solid-state sensors along the dual side sensor grooves.
This adjustable-stroke variant allows you to fine-tune the retract position at commissioning without adding external stops or swapping the cylinder. The 25 mm carbon steel rod and M20x1.5 rod thread handle demanding side loads, while the PT tapered G1/2 port ensures a tight pneumatic seal. It features adjustable air cushions at both ends to decelerate the heavy 100 mm piston smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-10S Is Used
Precision End-Stop Tuning
Dial in the exact 80-90 mm retract position during machine commissioning to set precise clamping or pressing depths without mechanical shims.
Product Changeover
Quickly adjust the stroke end-position by up to 10 mm when switching the production line to a slightly different product size or format.
High-Force Positioning
Leverage the 3927 N push force to move and position heavy jigs or workpieces, relying on the rear stopper to set the final resting coordinate.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-10S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (2268 N pull at 0.5 MPa) cannot provide enough force, but you want to avoid the bulk of a 125 mm unit. The 10 mm rear adjustment screw is ideal for dialing in exact end-stops during machine setup or product changeover, unlike a fixed-stroke SAI cylinder. For any load-holding requirements without live air pressure, note that the adjuster acts only as a travel stop, not a lock; you should specify an SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 10 mm adjustment, PT G1/2 port, and -S magnet. SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The 90 mm stroke is short enough that extra external guiding for the rod is generally unnecessary.
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 SAIJ100X90-10S FAQ
At a 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 allows you to trim the effective travel back by up to 10 mm, creating an 80-90 mm usable stroke window from the 90 mm nominal stroke. This stopper sets the travel end but does not lock or hold the load without continuous live air pressure.
