About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-10S
The AirTAC SAIJ100X35-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 35 mm nominal travel by up to 10 mm for a precise 25-35 mm usable window. Delivering 3927 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and features an integrated magnet for position sensing.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during machine setup and product changeovers. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-10S Is Used
Short-Stroke Clamping
Ideal for high-force clamping tasks where exact material positioning is critical, using the 10 mm adjustment to dial in the perfect grip without mechanical shims.
Machine Changeover
Quickly reconfigure end-of-stroke limits for different product sizes on a packaging line, utilizing the 25-35 mm travel window for rapid setup.
Ejector Stations
Provides robust ejection force in compact machinery spaces, relying on the SUS304 rod for durability in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-10S the Right Cylinder?
Choose this 100 mm bore cylinder when an application demands high thrust (3927 N push at 0.5 MPa) within a very short travel distance. If your mechanism requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas heavier loads might necessitate a 125 mm bore providing 6136 N. The 10 mm adjustment range is ideal for fine-tuning end positions at commissioning without replacing the cylinder.
To match this ISO 15552 footprint for replacement, verify the 100 mm bore, 35 mm nominal stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live air, consider the SAIL or BSAI series instead, as the adjuster here is not a lock.
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 SAIJ100BX35-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the 35 mm nominal stroke by up to 10 mm, creating a 25-35 mm usable travel window. It functions as a mechanical stop to fine-tune end positions and does not lock the load without air pressure.
