About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-50
The AirTAC SAIJ100X900-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end during commissioning. With a 900mm nominal stroke and a 50mm adjustment range, it provides an exact 850-900mm usable travel window to dial in product changeovers without adding external stops.
This model uses a SUS420J2 stainless steel rod (material code A) and a PT tapered G1/2 port. It supports speeds of 30-800mm/s and includes sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts strictly as a travel stop to set deceleration, not as a lock, so live air pressure is required to hold the load.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-50 Is Used
Variable End-Stop Machining
Dial in the 850-900mm travel window on the fly to accommodate different part lengths without swapping out the entire cylinder assembly.
Product Changeover Lines
Quickly adjust the retract stop position during product size transitions on packaging or conveying equipment to maintain precise spacing.
Long-Stroke Machine Setup
Fine-tune the end-of-travel position during initial commissioning to absorb mechanical tolerances across a 900mm stroke length.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-50 the Right Cylinder?
The adjustable 850-900mm window is ideal for variable end-stops on long-stroke machinery. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.
When replacing an ISO 15552 cylinder, match the 100mm bore, 900mm stroke, 50mm adjustment, PT G1/2 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 900mm, the 25mm rod diameter and M20x1.5 thread carry significant side load, so an external guide is recommended to prevent rod wear.
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 SAIJ100AX900-50 FAQ
The rear adjusting screw lets you shorten the effective stroke by up to 50mm, creating an 850-900mm usable travel window. It acts as a mechanical stop to tune the end position and does not lock the load without live air pressure.
