About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-50
The AirTAC SAIJ160X500-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a robust 18095N push force at 0.9 MPa and incorporates a 50mm adjustment range, yielding a precise 450-500mm usable travel window for commissioning flexibility. The extruded aluminum barrel includes sensor grooves on both sides.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered port threads. The rear adjuster acts as a mechanical stop to dial in end positions without adding external stops. It is not a locking device, so live air pressure is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-50 Is Used
Heavy Machinery Setup
Fine-tune the 450-500mm travel window during heavy equipment assembly to achieve exact end-position tolerances without external stopper blocks.
Product Line Changeover
Quickly adapt automated lines to new product sizes by dialing back the stroke up to 50mm, minimizing downtime between production runs.
Press Positioning
Precisely set the retraction point on large pneumatic presses where a standard fixed 500mm stroke would require custom spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-50 the Right Cylinder?
Choose this 160mm bore model when an application demands higher force than the 125mm bore (which provides 11045N push at 0.9 MPa) but does not require the massive 3204kgf output of the 200mm bore. The 50mm rear adjustment screw is ideal for product changeovers, allowing operators to fine-tune the 450-500mm travel window without swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 160mm bore, 500mm stroke, PT port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts. Because the stroke is 500mm, the 40mm rod diameter needs an external guide to prevent excessive side loading and binding.
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 SAIJ160BX500-50 FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 500mm down to 450mm. It fine-tunes the end position but does not lock the load without live air pressure.
At 0.9 MPa, the SAIJ160X500-50 delivers a push force of 18095N and a pull force of 14074N. The maximum force at 1.0 MPa is 2050 kgf.
