About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-30
The AirTAC SAIJ160X45-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 45 mm travel that can be fine-tuned down by up to 30 mm, yielding a precise 15-45 mm usable stroke window. This allows you to dial in the exact end position at commissioning without swapping out the cylinder or adding external stops. Delivering 18095 N of push force at 0.9 MPa, it is built for heavy-duty positioning.
This specific configuration utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance, paired with a robust M36x2 rod thread and a G3/4 PT port. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. As an adjustable stopper, the rear screw sets the travel end-point but does not lock the load without live air pressure; for position holding without continuous pneumatic supply, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-30 Is Used
Press Stroke Tuning
Dial in the exact 15-45 mm compression distance during machine setup to accommodate varying material thicknesses without changing hardware.
Product Changeover Stops
Adjust the retract end-position on the fly to handle different package sizes on a packaging line, using the rear stopper to set the new datum.
Heavy-Duty Positioning
Leverage the 18095 N push force at 0.9 MPa to move heavy pallets or molds into place, fine-tuning the end-stop to avoid mechanical crashes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-30 the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (yielding 4523 N push at 0.9 MPa) lacks the required thrust, but a 200 mm bore (28274 N at 0.9 MPa) is excessive for your frame. The adjustable 15-45 mm travel window is ideal for applications requiring variable end-stops or frequent product changeovers, replacing the need for fixed-stroke SAI cylinders when exact final positioning must be tuned on the machine.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 45 mm nominal stroke, 30 mm adjustment range, G3/4 PT port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 40 mm rod handles high loads, ensure proper alignment to avoid side-load stress on the rod seals.
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 SAIJ160BX45-30 FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates 18095 N of push force and 14074 N of pull force. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 45 mm stroke by up to 30 mm. This creates a usable travel window of 15-45 mm, enabling fine-tuning of the end position during commissioning. The adjuster only sets the travel end and does not hold the load without live air pressure.
