About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-75
The AirTAC SAIJ160X80-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 80 mm travel that can be fine-tuned backward, yielding a usable window of 5-80 mm for precise end-position calibration. Built to deliver immense thrust, it generates 14074 N of push force and 9425 N of pull force at a 0.7 MPa operating pressure.
This variant is configured with a SUS304 stainless steel rod for superior corrosion resistance in demanding environments. It uses PT tapered port threads and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-75 Is Used
Heavy Press Tuning
Dial in the exact 5-80 mm pressing distance during commissioning to accommodate material thickness variations without changing the cylinder.
Product Changeover
Rapidly adjust the end-stop position on automated lines when switching to a new product size, minimizing downtime and mechanical rework.
Corrosive Forming
Leverage the SUS304 stainless steel rod for heavy-duty forming or clamping tasks in humid or washdown manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-75 the Right Cylinder?
Select this 160 mm bore when an application requires heavy force that exceeds the 5497 N push capability of a 100 mm cylinder, but falls short of needing the 21991 N output of a 200 mm bore. The 75 mm adjustment range is ideal for machine setup and product changeover, allowing operators to dial in the exact end-stop without swapping hardware or adding external stops. For strokes of 80 mm, side-load risks are minimal, but an external guide is still recommended for heavy lateral loads.
Because the rear adjuster acts strictly as a mechanical stop and the air cushions only manage deceleration, this cylinder cannot hold a load without live air pressure. If your application requires true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series instead. This model is dimensionally interchangeable per ISO 15552 standards.
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 SAIJ160BX80-75 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. At the maximum pressure of 1.0 MPa, it achieves a push force of 20000 N.
The rear adjuster screw acts as a mechanical stop that can trim the effective travel back by up to 75 mm. This gives the 80 mm nominal stroke a usable window of 5 to 80 mm, allowing precise end-position tuning without swapping the cylinder.
