Airtac SAIJ160 Adjustable Cylinder SAIJ160BX35-30S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX35-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 35mm 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 SAIJ160BX35-30S
The AirTAC SAIJ160X35-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 5-35 mm window without adding external stops. Equipped with a SUS304 stainless steel rod and a PT tapered port, it delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa and peaking at 18095 N at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with CMSE reed and DMSE electronic switches for precise position verification.
Because the rear adjuster acts purely as a mechanical stop that sets the deceleration point alongside the variable air cushion, it cannot hold a load without live air pressure. For true load-holding requirements, you should pivot to an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock. This SAIJ model uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX35-30S Is Used
Heavy Press Tuning
Dial in the exact 5 to 35 mm travel window on a heavy press to accommodate varying material thicknesses without swapping out the entire actuator.
Machine Changeover
Quickly adjust the retract end-stop during product size changeovers on a packaging line, saving downtime compared to repositioning fixed physical stops.
Assembly End-Positioning
Fine-tune the final end position of a heavy clamping assembly during commissioning to ensure parts mate perfectly without over-stroking.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX35-30S the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when your application requires heavy force and exact end-position tuning during commissioning or product changeover, rather than the fixed travel of a standard SAI. If you need slightly less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas stepping up to a 200 mm bore provides 15080 N. The robust 40 mm SUS304 rod and M36x2 thread handle high side loads well, but even with short travel, you must ensure proper external guiding to prevent binding.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 35 mm stroke, 30 mm adjustment, PT port, and the -S magnet requirement. The operational speed range for this size is 30-500 mm/s.

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 SAIJ160BX35-30S FAQ
At 0.5 MPa it provides 10053 N of push and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The nominal 35 mm stroke can be mechanically dialed back by up to 30 mm via a rear adjusting screw, creating a usable travel window of 5 to 35 mm to fine-tune the retract end position.
