About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75S
The AirTAC SAIJ160X90-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 90 mm travel back by up to 75 mm, creating a highly versatile 15 to 90 mm usable stroke window. Built with a SUS304 stainless steel rod and PT tapered ports, it generates 10053 N of pull force and 14074 N of push force at 0.7 MPa, placing it firmly in the heavy-duty class.
This unit includes a magnetic piston for electronic DMSE solid-state or CMSE reed switch detection. The external adjuster functions purely as a mechanical stop for fine-tuning end positions during commissioning; it does not hold the load without live air pressure, so applications requiring true load-holding need a SAIL pneumatic lock or BSAI clamp-lock cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 15 to 90 mm during machine setup without adding external spacers or changing the cylinder.
Product Changeover
Quickly adjust the stroke length on packaging lines when handling different product sizes, reducing downtime between runs.
Heavy Force Testing
Leverage the 14074 N push force at 0.7 MPa for heavy-duty press or clamping operations that require precise end-position control.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75S the Right Cylinder?
Choose this 160 mm bore when 125 mm bore cylinders (providing 5734 N pull at 0.5 MPa) lack the necessary force, but stepping up to a 200 mm bore (15080 N pull at 0.5 MPa) would be excessive overkill. The 15-90 mm adjustable travel window is ideal for product changeovers on a packaging line where end-stops frequently shift, eliminating the need to physically swap out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 90 mm stroke, 75 mm adjustment range, PT port threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. Because the 90 mm stroke is relatively short for this large bore, side-load risks are minimal, but an external guide is still recommended for heavy offset loads.
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 SAIJ160BX90-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 12566 N of pull force. At 0.5 MPa, it provides 10053 N of push and 9425 N of pull force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 90 mm nominal stroke by up to 75 mm, providing a usable travel window of 15 to 90 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
