Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-100S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 850mm 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 SAIJ160AX850-100S
The AirTAC SAIJ160X850-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 750 to 850 mm. Fitted with a SUS420J2 stainless steel rod and PT tapered ports, it delivers a robust 14074 N of push force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and because this configuration includes the -S magnet, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors for precise position detection.
This 850 mm stroke falls within the standard 1500 mm maximum for the 160 mm bore, but the integrated 100 mm adjustment mechanism allows you to dial back the end-of-travel position during commissioning without swapping out the cylinder. The rear adjuster functions strictly as a travel stop that works alongside the 50 mm air cushions to decelerate the load; it does not hold the position without live air pressure. For applications requiring true load-holding, a SAIL pneumatic lock or BSAI clamp-lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-100S Is Used
Variable End-Stop Setup
Dial in the exact 750-850 mm end position during machine commissioning to accommodate varying material lengths without adding external physical stops to the frame.
Product Size Changeover
Quickly retract the travel by up to 100 mm on automated packaging lines when switching to a smaller product format, minimizing downtime between production runs.
Heavy Material Handling
Leverage the 14074 N push force at 0.7 MPa to shift heavy pallets or industrial components, using the rear stopper to fine-tune the deceleration distance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-100S the Right Cylinder?
Selecting this 160 mm bore over the smaller 125 mm neighbor (which provides 8590 N push at 0.5 MPa) is driven by the need for high thrust, offering 10053 N at 0.5 MPa. An adjustable stroke is chosen over a fixed SAI cylinder when a machine requires variable end-stops to accommodate product-size changeovers, allowing you to fine-tune the 750-850 mm travel window on the fly. When matching this ISO 15552 replacement, verify the 160 mm bore, 850 mm stroke, 100 mm adjustment range, PT port threads, and the -S magnet requirement.
Because the stroke is 850 mm, the 40 mm diameter rod and M36x2 thread will carry significant side loads, but an external guide is still mandatory to prevent rod bending and premature seal wear over long unsupported travels. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, intentionally omitting FB, CA, CB, and CR styles.
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 SAIJ160AX850-100S FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can deliver up to 18095 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective travel from the 850 mm nominal stroke down to as little as 750 mm. It allows you to fine-tune the end position at commissioning without swapping the cylinder, though it does not lock the load without live air pressure.
