About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-40S
The AirTAC SAIJ160X150-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stopper. It provides a 110-150mm usable travel window, allowing you to dial back the 150mm nominal stroke by up to 40mm during commissioning. Delivering 14074N of push force at 0.7MPa, it handles heavy-duty positioning tasks with precision.
This unit includes a standard carbon steel rod and PT tapered ports. The -S magnet enables position sensing via AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. The extruded aluminum barrel design omits tie-rod construction, and the available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-40S Is Used
Heavy Assembly Positioning
Fine-tunes the end-stop within the 110-150mm window to seat large heavy-duty components accurately during automated assembly.
Product Line Changeover
Quickly adjusts the retract end-position by up to 40mm to accommodate new product sizes without physically changing the cylinder.
Machine Commissioning
Allows engineers to dial in the exact travel distance on-site during initial setup, preventing mechanical crashes and over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-40S the Right Cylinder?
Choose this 160mm bore when 10045N of pull force at 0.5MPa is required for moving heavy assemblies; stepping down to an 80mm bore yields only 2268N pull. The 40mm adjuster is ideal for product changeovers, letting you set variable end-stops without swapping the cylinder or adding external stops. For applications needing to hold a load without live air pressure, note that this adjuster acts only as a travel stop, not a lock—consider the AirTAC SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 160mm bore, 150mm stroke, up to 40mm adjustment, PT ports, and the -S magnet requirement. Because the 150mm stroke is relatively short for this large bore, side-load risks are minimal, but the robust 40mm rod and M36x2 thread handle high torque and shear stresses effectively.
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 SAIJ160X150-40S FAQ
At 0.7MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 150mm nominal stroke by up to 40mm, creating a 110-150mm usable travel window. It only sets the end position and does not lock the load without live air.
