About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-100
The AirTAC SAIJ160X280-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel anywhere within a 180 to 280 mm window. It delivers massive thrust, generating 18095 N of push force at 0.9 MPa, making it suitable for heavy-duty pressing and clamping. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position detection.
This specific configuration uses a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw functions purely as a mechanical stop to dial in the end position during commissioning; it does not lock the load, so live air is required to hold position. For load-holding without air pressure, an external rod lock or a SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-100 Is Used
Heavy-Duty Pressing
Dial in the exact 180-280 mm travel depth for varying material thicknesses during heavy assembly or pressing tasks without changing cylinders.
Product Changeover
Quickly adjust the rear stopper to accommodate new product lengths on a high-tonnage production line, saving setup time and eliminating external stop hardware.
Automated Forming
Leverage the 18095 N push force at 0.9 MPa for robust forming operations while fine-tuning the end position to compensate for tooling wear.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-100 the Right Cylinder?
Choose this 160 mm bore when you need substantial force that smaller bores cannot provide, such as stepping up from a 125 mm cylinder that yields 11045 N at 0.9 MPa. The 100 mm adjustment range is ideal for machines processing varying product sizes, allowing you to change the end-stop on the fly without swapping out the entire cylinder or adding external stopper blocks. If your application requires dead-stop load holding without continuous air pressure, step up to a SAIL air-released lock or BSAI clamp-lock cylinder instead of relying on the SAIJ adjuster.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 280 mm stroke, 100 mm adjustment range, PT G3/4 port threads, and SUS304 rod material. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 280 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread handle high side-loads, but you should still use an external guide rail to prevent rod binding over long unsupported travel.
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 SAIJ160BX280-100 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095 N of push force and 9425 N of pull force at 0.5 MPa. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 280 mm stroke by up to 100 mm, creating a usable travel window of 180 to 280 mm. It only sets the end position and does not lock the load without live air pressure.
