About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-75S
The AirTAC SAIJ160X160-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It generates 14074N of push force at 0.7 MPa and features a robust 40mm carbon steel rod with M36x2 threading. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed in the dual-side extruded barrel grooves.
This specific SKU provides a nominal 160mm stroke that can be dialed back by up to 75mm, creating an 85-160mm usable travel window for exact end-position tuning. The rear stopper screw allows you to shorten the effective stroke at commissioning without swapping the cylinder or adding external stops. It operates at speeds of 30-500mm/s and utilizes PT tapered port threads paired with 50mm adjustable air cushions to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-75S Is Used
Heavy Press Fine-Tuning
Dial in the exact 85-160mm end-stop during heavy press commissioning to accommodate material thickness variations without machining new hard stops.
Product Size Changeover
Rapidly adjust the rear stroke screw on an assembly line when switching between product sizes, leveraging the 14074N force to handle large components.
Variable End-Stop Setup
Utilize the 75mm adjustment range to test multiple extend positions on a prototype fixture, finding the optimal travel distance before finalizing the design.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-75S the Right Cylinder?
Choose this 160mm bore cylinder when an application requires substantial force—such as 14074N push at 0.7 MPa—that exceeds the 5497N push capacity of the smaller 100mm bore variant. The adjustable 85-160mm travel window is ideal for product changeovers or fine-tuning machine setup, whereas a fixed-stroke SAI cylinder lacks this commissioning flexibility. To replace an ISO 15552 cylinder, match the 160mm bore, 160mm stroke, 75mm adjustment, PT port thread, and -S magnet.
Because the 160mm stroke falls below the 300mm side-load threshold, external guides are less critical here than on longer strokes, though the 40mm rod handles standard loads well. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ cannot hold a load without live air. For fail-safe load holding, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160X160-75S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. It can achieve a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to trim the effective stroke by up to 75mm, creating an 85-160mm usable travel window from the 160mm nominal stroke. This stopper sets the end position but does not lock the load without continuous air pressure.
