About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-100
The AirTAC SAIJ100X600-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 600mm stroke that can be dialed back by up to 100mm, giving you a precise 500-600mm usable travel window for exact end-position tuning during commissioning. In this configuration, the bore generates 5497N of push force and 3681N of pull force at 0.7MPa, placing it firmly in the heavy-duty payload class.
This model uses a standard carbon steel piston rod with an M20x1.5 rod thread, paired with a G1/2 port. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing direct mounting of AirTAC CMSE reed and DMSE electronic solid-state switches if a magnet is specified later. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position without adding external stops, while the shared variable air cushions at both ends manage end-of-stroke deceleration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-100 Is Used
Multi-Size Machining
Dial in the retract stop across the 500-600mm window to accommodate different part lengths on a single CNC cell without changing cylinders.
Adjustable Diverters
Fine-tune the actuator endpoint on the fly during production line changeovers to handle varying package dimensions accurately.
Heavy-Duty Positioning
Leverage the 5497N push force at 0.7MPa to shift heavy pallets, using the 100mm adjustment to set exact machine home positions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-100 the Right Cylinder?
Choose this 100mm bore when a 63mm cylinder (1402N pull at 0.5MPa) cannot move the load, but a 125mm unit is oversized. The 100mm adjustment range is selected when a machine handles multiple product sizes, allowing the retract end-stop to shift across a 500-600mm window without physically swapping the cylinder. Because the 600mm stroke is long, the M20x1.5 rod and carbon steel construction handle high side-loading forces, but an external guide is still recommended to prevent rod binding.
For an exact ISO 15552 replacement match, verify the 100mm bore, 600mm stroke, 100mm adjustment code, G1/2 PT tapered port, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting style. Remember that the rear adjuster is a travel stop, not a lock; this plain cylinder will not hold its load without live air pressure. If you need true load-holding, use an external rod lock or pilot-operated check valve, or step up to the SAIL or BSAI variants.
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 SAIJ100X600-100 FAQ
At 0.7MPa operating pressure, this 100mm bore cylinder provides 5497N of push force and 3681N of pull force. It can deliver a maximum push force of 7068N at 0.9MPa.
The rear mechanical adjuster lets you shorten the 600mm nominal stroke by up to 100mm, creating a 500-600mm usable travel window. The adjuster sets the retract end-stop and does not lock the load without live air pressure.
