About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-100S
The AirTAC SAIJ100X290-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 190-290 mm usable travel window. Delivering 7068 N of push force at 0.9 MPa, it handles heavy positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection.
A defining feature of this SKU is the 100 mm adjustment range, allowing you to dial back the nominal 290 mm stroke during commissioning without swapping hardware. The carbon steel rod with an M20x1.5 thread provides robust load capacity, while the -S magnet integrates directly with AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-100S Is Used
Variable End-Stop Configuration
Dial in the exact 190-290 mm travel distance during machine setup to accommodate different material lengths without bolting on external stops.
Product Changeover Systems
Quickly reconfigure the stroke on packaging lines handling varying carton sizes, using the 100 mm adjustment window to adapt end positions.
Heavy Press Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy tooling, fine-tuning the final approach distance via the rear screw for precise contact.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-100S the Right Cylinder?
Choose this 100 mm bore when you need significantly more thrust than the 63 mm bore (2182 N at 0.5 MPa) but want to avoid the larger footprint of a 125 mm unit. The 100 mm adjustment range is ideal for machines running multiple product sizes, letting operators set variable end-stops on the fly. Because the stroke is 290 mm, use an external guide to prevent rod side-load wear.
For an exact ISO 15552 replacement, match the 100 mm bore, 290 mm stroke, PT tapered port threads, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, select a SAIL or BSAI cylinder.
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 SAIJ100X290-100S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder generates 7068 N of push force and 3681 N of pull force.
The rear adjuster screw lets you mechanically shorten the 290 mm stroke by up to 100 mm, providing a usable travel window of 190 to 290 mm. The adjuster acts as a stop and does not lock the load without air pressure.
