Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-50S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 65mm 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 SAIJ100X65-50S
The AirTAC SAIJ100X65-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 3927 N push force at 0.5 MPa, scaling up to 7068 N at 0.9 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches mounted into the dual-side sensor grooves. A standard PT tapered port thread and carbon steel rod equip this unit.
With a 65 mm nominal stroke and a 50 mm adjustment range, this model yields a highly versatile 15 to 65 mm usable travel window. The rear mechanical stopper lets you dial back the end-of-stroke position during commissioning or product changeovers without adding external physical stops. The adjuster acts purely as a travel stop to set deceleration alongside the air cushions; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-50S Is Used
Product Changeovers
Dial in the exact end-stop position for varying package sizes on a packaging line without swapping out the entire cylinder assembly.
Machine Setup
Fine-tune the 15-65 mm travel window during initial commissioning to perfect pressing or clamping end positions.
Variable End Stops
Use the 50 mm rear adjuster to modify the effective stroke for testing different operational parameters.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-50S the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder (delivering 2513 N at 0.5 MPa) lacks sufficient thrust, but a 125 mm bore is physically too large for the machine envelope. The 50 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, allowing the effective stroke to be trimmed down to 15 mm. For load-holding without continuous air pressure, this plain SAIJ cylinder is insufficient since the adjuster is only a stop; select an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder instead.
To replace an ISO 15552 cylinder, match the 100 mm bore, 65 mm stroke, 50 mm adjustment, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, explicitly omitting FB, CA, CB, and CR. Because the 25 mm rod and M20x1.5 thread handle high side loads, ensure proper guiding for your specific mechanics.
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 SAIJ100X65-50S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 65 mm nominal stroke anywhere within a 15 to 65 mm usable travel window. It functions as a travel stop and does not lock the load without live air pressure.
