About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-40S
The AirTAC SAIJ160X65-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 25-65 mm usable travel window from its 65 mm nominal stroke. Equipped with a SUS304 stainless steel rod and PT tapered ports, it generates 14074 N of push force at 0.7 MPa. This makes it highly effective for heavy-duty positioning tasks requiring exact end-stop tuning.
The rear adjuster acts as a mechanical stop to fine-tune the retract position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works directly with AirTAC CMSE reed and DMSE electronic sensors. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-40S Is Used
Heavy Press Tuning
Dial in the exact 25-65 mm travel window during machine commissioning to perfect heavy pressing operations without repositioning the entire cylinder assembly.
Product Changeover
Quickly adapt the retract end-stop for varying product sizes on a high-thrust line, utilizing the 40 mm adjustment to avoid costly mechanical modifications.
Beast Mode Assembly
Leverage the 14074 N push force at 0.7 MPa for driving large assemblies, using the rear screw to precisely set the final clamping position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-40S the Right Cylinder?
Select this 160 mm bore when a 100 mm bore (delivering 5497 N push at 0.7 MPa) lacks the necessary thrust, but a 200 mm bore (21991 N push) is excessive. The 40 mm adjustment range is ideal for product changeovers, allowing you to dial in the exact end position without swapping cylinders. For any stroke of 300 mm or more, you must use an external guide to prevent excessive side-loading on the rod.
This cylinder is dimensionally interchangeable per ISO 15552. Configuration: 160 mm bore, 65 mm stroke, 40 mm adjustment, PT ports, SUS304 rod, and a magnet for sensors. The rear adjuster only sets the travel end; it does not hold the load without live air. For true load-holding without pressure, use an SAIL lock, BSAI clamp-lock, or external rod lock.
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 SAIJ160BX65-40S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It reaches a maximum of 18095 N push at 0.9 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 65 mm nominal stroke by up to 40 mm, creating a 25-65 mm usable travel window. It requires live air to move and does not lock or hold the load pneumatically.
