About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-50
The AirTAC SAIJ160X280-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to trim the effective travel back by up to 50 mm. This yields a highly flexible 230-280 mm usable stroke window, letting you dial in the exact retract position at commissioning without adding external stops. It delivers substantial force, pushing with 14074 N at 0.7 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the end-of-travel position; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-50 Is Used
Heavy Machinery Setup
Fine-tune the 230-280 mm travel window during machine commissioning to perfectly align heavy clamping arms without machining custom spacers.
Product Size Changeovers
Quickly adapt the retract stop for varying pallet widths on a conveyor line, using the 50 mm adjustment range to handle multiple product sizes on one cylinder.
Press Positioning
Dial in the exact bottoming position for a light assembly press, ensuring precise contact without over-stroking the tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-50 the Right Cylinder?
Choose this 160 mm bore when you need heavy thrust but require variable end-position tuning on the fly. If your application only needs 9425 N of pull force at 0.5 MPa, stepping down to a 125 mm bore saves space, but this 160 mm bore is required for loads demanding 10053 N of pull at 0.5 MPa. The adjustable stroke is ideal for product-size changeovers on a line, eliminating the need to physically swap out a fixed-stroke SAI cylinder for each new part dimension. To match this ISO 15552 replacement, specify the 160 mm bore, 280 mm stroke, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and SUS304 (B) rod material.
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 SAIJ160BX280-50 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 10053 N of pull force.
The rear adjuster screw lets you shorten the 280 mm nominal stroke by up to 50 mm, creating a usable travel window of 230-280 mm. This mechanical stop sets the end position but does not lock the load without continuous air pressure.
