About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-20
The AirTAC SAIJ160X500-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a robust 18095N push force at 0.9 MPa and uses a PT G3/4 tapered port. By turning the rear screw, you can shorten the effective travel from its nominal 500 mm down to 480 mm, creating a precise 480-500 mm usable window for exact end-position tuning.
This heavy-duty actuator features a 40 mm SUS304 stainless steel rod (material code B) for superior corrosion resistance. The extruded aluminum barrel includes dual sensor grooves, and the rod thread is M36x2. Because the adjustment mechanism acts solely as a mechanical stop and does not lock the load, you must maintain live air pressure to hold position.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-20 Is Used
Heavy Press Tuning
Dial in the exact 480-500 mm retract distance on large pneumatic presses during setup, ensuring precise crushing or forming depth without external shims.
Product Changeover
Quickly adapt automated heavy-duty machinery to accommodate slightly different product lengths by adjusting the built-in 20 mm stroke stopper on the fly.
Large Assembly Jigs
Provide adjustable end-stop positioning for massive components on the assembly line, leveraging the 18095N force capacity to move substantial loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-20 the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore falls short—delivering 1130N versus this model's 18095N at 0.9 MPa. The 20 mm adjustable range is ideal for fine-tuning the retract end during machine commissioning without adding external stops. For a fixed end-position, a standard SAI cylinder suffices, but the SAIJ variant excels during product changeover. Since the 500 mm stroke is substantial, always use an external guide to prevent side-loading damage to the 40 mm rod. Note that SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR brackets. If you need true load-holding without live air, select the SAIL or BSAI series instead.
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 SAIJ160BX500-20 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095N and a pull force of 9425N. The maximum force at 1.0 MPa is 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 20 mm. This creates a usable travel window of 480 to 500 mm, allowing precise end-position calibration during commissioning without swapping the cylinder.
