About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-30S
The AirTAC SAIJ100X500-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, pushing 7068N at 0.9 MPa, making it well-suited for heavy-duty positioning. The integrated magnet allows direct mounting of CMSE reed and DMSE electronic sensors along the dual-side extruded barrel grooves for precise end-of-stroke detection.
With a nominal 500 mm stroke and a 30 mm adjustment range, the usable travel window can be fine-tuned from 470 to 500 mm. This built-in mechanical stop allows you to dial in exact end positions during commissioning or product changeovers without adding external physical stops. The adjuster solely dictates the travel endpoint and deceleration phase; it is not a locking mechanism and will not hold a load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-30S Is Used
Heavy Press Tonnage Tuning
Dial in the exact 470-500 mm end position for a heavy press operation, ensuring precise material deformation without reconfiguring the entire machine bed.
Product Size Changeover
Rapidly adapt a diverter arm on a packaging line to accommodate varying box lengths by adjusting the retract stop up to 30 mm on the fly.
Commissioning Calibration
Fine-tune the final resting position of a heavy industrial platform during initial machine setup, compensating for mechanical tolerances without external spacers.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-30S the Right Cylinder?
Select this 100 mm bore cylinder when an application demands high force combined with variable end-position tuning. If 7068N of push force at 0.9 MPa exceeds your requirements, stepping down to an 80 mm bore yields 4523N, whereas moving up to a 125 mm bore provides 11045N. The 25 mm piston rod and M20x1.5 rod thread offer robust resistance to side loads, but with a 500 mm stroke, an external guide rail is strongly recommended to prevent rod binding and premature seal wear.
Choose the adjustable SAIJ format over a fixed-stroke SAI when a machine requires frequent product-size changeovers or precise end-stop calibration without physically swapping cylinders. For applications that must maintain position safely during a loss of air pressure, this cylinder is insufficient; you should utilize an SAIL pneumatic lock, a BSAI clamp-lock, or an external pilot-operated check valve. This configuration features PT tapered port threads, a G1/2 air supply, and the -S magnet option. It supports the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ100X500-30S FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder generates a push force of 7068N and a pull force of 3681N. It can deliver a maximum push force of 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the nominal 500 mm down to 470 mm. This creates a 470-500 mm usable window for fine-tuning end positions during commissioning, but it does not lock the load without live air pressure.
