About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-40
The AirTAC SAIJ100X65-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927N of push force at 0.5 MPa. By integrating an external adjusting screw at the rear, this cylinder allows you to fine-tune the effective travel down to a 25-65 mm window, eliminating the need to physically swap components during product changeovers.
Built with a carbon steel piston rod and a PT tapered G1/2 port, it handles substantial loads while maintaining standard ISO 15552 mounting interchangeability. The extruded aluminum barrel features dual sensor grooves, though this specific SKU omits the magnet, meaning position detection via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-40 Is Used
Variable End-Stop Forming
Dial in the exact 25 to 65 mm retraction depth for metal forming or bending operations without changing out the physical cylinder.
Product Size Changeover
Quickly adapt automated machinery to different product lengths by turning the rear adjuster screw during line changeovers.
Heavy-Duty Clamping
Leverage the 7068N push force at 0.9 MPa to secure heavy workpieces, using the adjustable stop to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-40 the Right Cylinder?
Choose this 100 mm bore when your application requires higher thrust than a neighboring 80 mm cylinder (which provides 2513N push at 0.5 MPa), but without stepping up to larger, space-consuming equipment. The adjustable stroke is ideal for machine setups requiring variable end-stops, acting as a hard stop rather than a lock. If your process demands true load-holding without live air pressure, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 65 mm nominal stroke, 40 mm adjustment range, PT port thread, and your required mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Since the stroke is relatively short at 65 mm, side-loading risks are minimal, but external guides are still recommended for heavy lateral loads.
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 SAIJ100X65-40 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927N of push force and 3681N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 801 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 65 mm nominal stroke by up to 40 mm. This creates a usable travel window of 25 to 65 mm for fine-tuning the end position at commissioning.
