Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20S 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 SAIJ160AX700-20S
The AirTAC SAIJ160X700-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 700 mm travel by up to 20 mm for a precise 680-700 mm usable window. It delivers immense thrust, generating 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty press and lift operations. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches.
This model utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads with a G3/4 connection. The 40 mm rod diameter and M36x2 thread provide robust mechanics, though an unsupported 700 mm stroke requires external guidance to manage side loads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20S Is Used
Heavy-Duty Press Tuning
Dial in the exact 680-700 mm end-stop during machine commissioning to accommodate varying material thicknesses without replacing the cylinder.
Product Size Changeover
Quickly adjust the retract position on a packaging line when switching to larger product dimensions, using the rear screw to set the new travel limit.
Large Assembly Fixturing
Leverage the 10053 N push force at 0.5 MPa to position heavy automotive components, relying on the 40 mm rod and external guides to handle the load.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-20S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands extreme force that a 125 mm bore cannot provide, or when stepping down from a 200 mm bore to save space. At 0.5 MPa, the 125 mm bore yields 6136 N push force, whereas this 160 mm model pushes 10053 N, making the upgrade essential for high-tonnage tasks. The adjustable 680-700 mm window is ideal for product changeovers, allowing operators to fine-tune the retract end position without swapping cylinders or adding external stops. For load-holding without continuous air pressure, pair this cylinder with an external rod lock or consider the AirTAC SAIL or BSAI series, as the SAIJ adjuster is not a locking mechanism.
To match this exact ISO 15552 interchangeable replacement, specify: 160 mm bore, 700 mm stroke, 20 mm adjustment range, PT port threads, SUS420J2 rod material, and the -S magnet option. Mounting choices are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 700 mm stroke is long, ensure your framework includes an external guide to prevent rod binding under heavy 30-500 mm/s operational speeds.
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 SAIJ160AX700-20S FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At 0.7 MPa, the push force increases to 14074 N. The maximum push force is 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 700 mm nominal stroke by up to 20 mm, providing a usable travel window of 680 to 700 mm. It is a stop for fine-tuning end positions, not a lock to hold the load without air pressure.
