About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-30
The AirTAC SAIJ100X500-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 500 mm stroke back by up to 30 mm, creating a precise 470-500 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE position switches if a magnet is specified later.
This model features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. The rear adjuster acts as a mechanical stop to fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder. It supports a speed range of 30-800 mm/s and offers adjustable air cushions at both ends to decelerate the 25 mm rod smoothly.

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 SAIJ100AX500-30 Is Used
Machine Changeover
Dial in the exact retract position within the 470-500 mm window when switching product sizes on a line, avoiding the need to physically swap cylinders or rework external stop blocks.
Variable End-Stop Diverter
Fine-tune the actuation endpoint of a diverter arm during commissioning to perfectly match the conveyor profile and ensure packages are pushed accurately without mechanical adjustments.
Press Stroke Tuning
Adjust the effective working stroke on a light assembly press to accommodate different material thicknesses, using the 30 mm trim range to set the precise contact depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-30 the Right Cylinder?
The adjustable rear stopper is ideal for machine setups requiring variable end stops without adding external physical stops.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 500 mm stroke, 30 mm adjustment, G1/2 PT port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 500 mm, the long unsupported rod is susceptible to side-loading; always guide the load externally to prevent binding. Note that the rear adjuster is a travel stop, not a lock—the SAIJ does not hold position without live air, so for load-holding without pressure, consider SAIL or BSAI types.
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 SAIJ100AX500-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf (approx. 7854 N) of push force.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the 500 mm nominal stroke by up to 30 mm, providing a usable travel window of 470-500 mm. This enables fine-tuning of the end position at commissioning without changing the cylinder itself.
