About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-30
The AirTAC SAIJ160X350-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 30 mm of end-position tuning. This yields a usable travel window of 320-350 mm, enabling precise retraction calibration during commissioning without adding external stops. The 160 mm bore delivers substantial thrust, pushing 14074 N at 0.7 MPa and 18095 N at 0.9 MPa.
This variant incorporates a SUS304 stainless steel piston rod (option B) for superior corrosion resistance and is equipped with PT tapered ports. It uses variable air cushions at both ends to decelerate heavy loads across its 350 mm stroke. The rear adjuster functions strictly as a mechanical stop to set the travel end-point; it does not hold the load without live air pressure, a task requiring a SAIL or BSAI locking cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-30 Is Used
Machine Changeover Calibration
Dial in the 320-350 mm retract position during product size transitions without replacing the cylinder or bolting on external physical stops.
Heavy Pressing Operations
Leverage the 18095 N push force at 0.9 MPa for heavy assembly tasks, using the rear stopper to fine-tune the final pressing depth precisely.
Corrosive Environment Handling
Utilize the SUS304 stainless steel rod and high force output in washdown or mildly corrosive industrial settings where standard carbon steel rods would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-30 the Right Cylinder?
Choose this 160 mm bore when an application demands high thrust—such as 14074 N push at 0.7 MPa—that exceeds the 11045 N push capacity of the neighboring 125 mm bore. The adjustable stroke is ideal for product changeovers where the exact end-of-stroke position varies by up to 30 mm, eliminating the need to physically swap cylinders. For load-holding without continuous air pressure, specify a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead of relying on the SAIJ adjuster.
Because the 350 mm stroke is substantial, the 40 mm diameter SUS304 rod and its M36x2 thread provide robust support, but an external guide is recommended to prevent side-load damage on long unsupported loads. This model is dimensionally interchangeable per ISO 15552 and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Operating speed 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 SAIJ160BX350-30 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. It achieves a maximum push force of 10053 N at the standard 0.5 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective travel from the 350 mm nominal stroke, providing a usable window of 320-350 mm. It only sets the end position and decelerates the load via air cushions; it does not lock or hold the load without live air pressure.
