About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-40S
The AirTAC SAIJ160X140-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 10053N of push force at 0.5 MPa and features a 40mm adjustment range, creating a usable travel window of 100-140mm for precise end-position tuning during commissioning. This variant includes a magnet for CMSE reed and DMSE solid-state sensors, utilizes a PT tapered port, and has a standard carbon steel piston rod.
The rear adjustment screw acts strictly as a mechanical stop to dial in the retract position without adding external stops. It does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-40S Is Used
Heavy Press Tuning
Dial in the exact 100-140mm end position on heavy stamping presses during setup, absorbing impact via the 50mm cushion.
Product Changeover
Quickly adjust the retract stop for varying product sizes on an automated line without replacing the entire cylinder.
Material Handling
Position large payloads with 10053N of force at 0.5 MPa, using the rear stop to fine-tune the drop-off point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-40S the Right Cylinder?
Choose this 160mm bore when the 100mm bore class (3927N push at 0.5MPa) is insufficient, but the 200mm bore (15708N) is excessive. The 40mm adjustable window is ideal for product changeovers on heavy machinery, allowing you to fine-tune the 140mm stroke without swapping the cylinder. For load-holding without live air, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 160mm bore, 140mm stroke, 40mm adjustment, PT G3/4 port, and -S magnet. The 40mm rod and M36x2 thread handle high side loads, but because the stroke is under 300mm, external guiding is less critical than with longer strokes.
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 SAIJ160 Adjustable Cylinder SAIJ160X140-40S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N.
The rear adjuster screw lets you trim the effective travel from the 140mm nominal stroke down to 100mm. This mechanical stop fine-tunes the end position but does not lock the load without continuous air pressure.
