About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-100S
The AirTAC SAIJ100X900-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing an 800-900 mm usable travel window from its 900 mm nominal stroke. It delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, utilizing a G1/2 PT tapered port and a 25 mm carbon steel rod. The integrated -S magnet enables position detection with AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual-side sensor grooves.
Featuring a 100 mm adjustment range, this cylinder allows precise end-position tuning during commissioning without swapping hardware. The rear screw acts purely as a travel stop for deceleration alongside the adjustable air cushions, meaning it cannot hold a load without live air pressure. For applications requiring position holding, consider the SAIL or BSAI locking variants.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-100S Is Used
Long-Stroke Forming
Dial in the exact 800-900 mm end-stop for large press or forming operations, allowing fine-tuning of the final position without remounting the cylinder.
Product Changeover
Adapt automated conveyor diverts or long-trail transfers to different pallet sizes instantly by adjusting the rear stopper screw up to 100 mm.
Machine Setup
Simplify commissioning on heavy machinery by using the rear adjuster to set the precise retracted position, eliminating the need for custom external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-100S the Right Cylinder?
Choose this 100 mm bore when a step down to the 80 mm variant (2513 N push at 0.5 MPa) lacks thrust, but you still need the flexibility to dial in a precise 800-900 mm stroke during product changeovers. The adjustable end-stop is ideal for variable end positions, whereas a fixed SAI cylinder is better for static, repeatable cycles. When specifying an ISO 15552 replacement, match the 100 mm bore, 900 mm stroke, 100 mm adjust code, G1/2 PT port, and the -S magnet requirement.
Because this model features a 900 mm stroke, the 25 mm carbon steel rod and M20x1.5 rod thread will experience amplified side-loading forces if the load is unsupported. An external guide mechanism is highly recommended to prevent premature seal wear and rod bending over this extended travel distance.

- ✓ 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 SAIJ100X900-100S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, creating an 800-900 mm usable travel window. This stopper only sets the travel end and does not lock the load without live air pressure.
