About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-10
The AirTAC SAIJ100X650-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927N push force at 0.5 MPa. It features a SUS304 stainless steel rod and PT tapered ports. By integrating a 10mm adjustment mechanism, this model creates a precise 640-650mm usable travel window, allowing you to dial in the exact retract position without swapping out the entire unit.
The rear adjuster functions strictly as a travel stop to set the end position and relies on the integrated air cushions for deceleration; it is not a locking mechanism and will not hold a load without continuous live air pressure. For position holding without air, consider an external rod lock or the related SAIL pneumatic lock series. This extruded aluminum profile cylinder includes dual sensor grooves for CMSE reed or DMSE electronic switches, though a magnet is not pre-installed on this specific configuration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-10 Is Used
End-Position Tuning
Dial in the exact retract distance within the 640-650mm window during machine commissioning to achieve precise seating without mechanical shims.
Product Changeover
Quickly adjust the stroke stop by a few millimeters on a packaging line when switching to a slightly different carton size.
Heavy Material Handling
Leverage the 3927N push force at 0.5 MPa to move heavy pallets or workpieces, relying on the fine adjustment to prevent hard crashes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-10 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder lacks thrust, as stepping up from the 80mm bore increases your 0.5 MPa push force from 2513N to 3927N. An adjustable stroke is highly beneficial here for product changeovers or commissioning fine-tuning, letting you trim the retract up to 10mm instead of installing external stops or ordering a fixed-stroke SAI cylinder. To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 650mm stroke, 10mm adjustment, PT port thread, and your required mounting option from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 kits.
Because this unit features a 650mm stroke, the 25mm rod diameter and M20x1.5 rod thread provide substantial rigidity, but an external guide is strongly recommended to prevent excessive side-loading on the piston over such an extended travel distance.
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 SAIJ100BX650-10 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster acts as a stopper that lets you shorten the nominal 650mm stroke by up to 10mm, creating a 640-650mm travel window. It sets the end position but does not lock the load without live air pressure.
