Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 650mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10S
The AirTAC SAIJ100X650-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning during commissioning. It provides a usable travel window of 640 to 650 mm, letting you dial back the nominal stroke by up to 10 mm without adding external stops. This 100 mm bore version delivers a robust 7068 N push force at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
It features a standard carbon steel piston rod with an M20x1.5 thread and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback. The variable air cushions at both ends decelerate the load, but remember the adjuster is a travel stop, not a lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10S Is Used
Machine Changeover
Fine-tune the 640-650 mm travel window during product size transitions to set exact end-stops without swapping cylinders.
Material Positioning
Leverage the 7068 N push force at 0.9 MPa to halt heavy pallets, using the rear screw to trim the final resting position.
Assembly Line Setup
Dial in the exact retract distance during initial commissioning, ensuring perfect alignment before locking down the machine sequence.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-10S the Right Cylinder?
Select this 100 mm bore model when your application requires substantial thrust—7068 N at 0.9 MPa—and a 650 mm stroke that needs micro-adjustments at the retract end. If you need less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, whereas moving up to a 125 mm bore provides 11045 N. Choose this adjustable SAIJ over a fixed-stroke SAI when you need to fine-tune the end-of-travel position during machine setup or product changeovers.
Because the stroke is 650 mm, the long unsupported piston rod is susceptible to side loads; always use an external guide to prevent premature seal wear and binding. To replace this cylinder, match the 100 mm bore, 650 mm stroke, 10 mm adjustment, PT port thread, and the -S magnet. Note that a plain SAIJ does not hold loads without live air; for pilot-operated locking without pressure, consider the SAIL or BSAI series. SAIJ uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100X650-10S FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, creating a 640-650 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
At an operating pressure of 0.9 MPa, the SAIJ100X650-10-S generates a push force of 7068 N. At 0.5 MPa, it provides 3927 N of push force.
