About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-10S
The AirTAC SAIJ160X550-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 550 mm travel by up to 10 mm. This yields a usable 540-550 mm end-position window for precise commissioning without adding external stops. It delivers substantial thrust, generating 14074 N of push force at 0.7 MPa and peaking at 18095 N at 0.9 MPa.
This SKU features a robust 40 mm SUS420J2 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and because this is a -S variant, it carries a magnet ready for AirTAC CMSE reed and DMSE solid-state switches. The rear adjustment screw functions strictly as a travel stop for deceleration, not a lock, so the load will not hold without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 540-550 mm bottoming position on a large assembly press during setup, accommodating material thickness variations without swapping cylinders.
Product Changeover Stops
Adjust the retract end-stop on a packaging conveyor line to handle different carton sizes rapidly, using the 10 mm trim window to perfect the transfer point.
Long-Stroke Diverter
Actuate a heavy diverter gate over 550 mm of travel, using the rear screw to synchronize the resting position precisely with downstream machinery.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-10S the Right Cylinder?
Select this 160 mm bore when an application requires heavy push force (14074 N at 0.7 MPa) but demands finer end-position tuning than a fixed-stroke SAI cylinder offers. If your process needs less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa. Because the 550 mm stroke is substantial, the 40 mm rod and M36x2 thread provide rigidity, but an external guide is strongly recommended to manage side loads over this long travel.
To match this ISO 15552 cylinder for a replacement, verify the 160 mm bore, 550 mm stroke, 10 mm adjustment range, PT G3/4 ports, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. For true load-holding without continuous air pressure, use an external rod lock or consider the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ160AX550-10S FAQ
This 160 mm bore cylinder generates a push force of 14074 N at 0.7 MPa and 18095 N at 0.9 MPa. The pull force at 0.7 MPa is 14074 N.
A rear stopper screw lets you shorten the effective travel from the nominal 550 mm down to 540 mm, creating a 10 mm fine-tuning window. This stopper only sets the end position and does not lock or hold the load without live air pressure.
