About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-20
The AirTAC SAIJ160X600-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 580 to 600 mm usable travel window, allowing you to dial back the nominal 600 mm stroke by up to 20 mm during machine commissioning without swapping the barrel or adding external stops. This bore generates 10053 N of push force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
Equipped with a SUS304 stainless steel rod and a PT tapered port, this 160 mm bore unit omits the FB, CA, CB, and CR mounting accessories, supporting only the Basic, FA, LB, TC, FTC, TCM1, and TCM2 ISO 15552 interfaces. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-20 Is Used
Heavy-Duty Press Tuning
Fine-tune the 580-600 mm stroke end-position on heavy presses during setup, ensuring precise contact without physically replacing the cylinder.
Product Size Changeover
Quickly adjust the end-stop to accommodate different product lengths on a packaging line, leveraging the 20 mm travel window for fast transitions.
Large Fixture Positioning
Position heavy machining fixtures accurately using the 10053 N thrust, relying on the rear screw to dial in the exact retract distance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-20 the Right Cylinder?
Select this 160 mm bore cylinder when your application requires substantial thrust—10053 N push and 9425 N pull at 0.5 MPa. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N of push force at the same pressure, whereas moving up to a 200 mm bore provides 15708 N. The integrated 20 mm adjustment mechanism is ideal for product changeovers on a line, letting you shift the end-stop precisely without replacing the entire actuator.
Because this unit features a 600 mm stroke, the 40 mm rod diameter and M36x2 thread still require an external guide to prevent excessive side-loading on the piston. Remember that the rear stopper only sets the travel end; for true load-holding without continuous air, you must integrate an external rod lock, a pilot-operated check valve, or select a SAIL or BSAI series cylinder. This non-magnetic variant operates at 30-500 mm/s.
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 SAIJ160BX600-20 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it delivers 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 600 mm down to 580 mm. It is a travel stop for fine-tuning end positions, not a lock, and it cannot hold the load without live air pressure.
