Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 700mm stroke, G3/4 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 SAIJ160 Adjustable Cylinder SAIJ160AX700-20
The AirTAC SAIJ160X700-20 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 18095N at 0.9 MPa, making it suited for heavy-duty positioning. The built-in adjusting screw allows you to fine-tune the retract position on the fly, creating a usable travel window of 680 to 700 mm without external stops.
This unit uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a PT tapered port thread. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. Since the stroke is 700 mm on a 160 mm bore, the 40 mm rod and M36x2 thread provide rigidity, but an external guide is still recommended to manage side loads over this long travel distance.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20 Is Used
Heavy Press Tuning
Dial in the exact 680-700 mm end-stop during heavy press commissioning to accommodate material thickness variations without machining new spacers.
Product Changeover Stops
Adjust the retract position on a packaging line when switching to a different pallet size, using the rear screw to set the new datum quickly.
Long-Stroke Indexing
Move large assemblies along a 700 mm travel path, relying on the 18095N thrust at 0.9 MPa to shift heavy jigs into the working zone.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20 the Right Cylinder?
Select this 160 mm bore cylinder when you need substantial force that smaller bores cannot provide, delivering 14074N push at 0.7 MPa compared to a 125 mm bore's 8590N. The 20 mm adjustable stroke is ideal for machine setups requiring precise end-position tuning during commissioning or product changeover, eliminating the need to swap out a fixed-stroke SAI cylinder. The rear adjuster acts purely as a travel stop for deceleration and does not hold the load without live air pressure; for dead-pilot load holding, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 700 mm nominal stroke, 20 mm adjustment range, PT G3/4 port, and the chosen mounting interface from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (omitting FB, CA, CB, and CR). Because the 700 mm stroke exceeds typical compact limits, always pair it with an external linear guide to prevent rod binding and premature wear.

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 SAIJ160AX700-20 FAQ
At 0.5 MPa it provides 10053N push and 9425N pull. At 0.9 MPa the push force reaches 18095N, with a maximum rated force of 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 20 mm, creating a 680 to 700 mm usable travel window. It sets the end position and decelereration but does not lock the load without continuous air pressure.
