Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30S
The AirTAC SAIJ160X200-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 200 mm nominal travel by up to 30 mm. This creates a precise 170-200 mm usable positioning window, ideal for fine-tuning end stops during commissioning without swapping out the entire actuator. It delivers substantial thrust, pushing with 10053 N and pulling with 9425 N at 0.5 MPa.
This variant features a robust 40 mm SUS304 stainless steel rod and includes a magnet for position sensing. You can mount CMSE reed or DMSE electronic switches directly into the sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop to set deceleration and end positions; it does not lock the load, so maintain live air or use an external pilot-operated check valve for load holding.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30S Is Used
Heavy Press Tuning
Dial in the exact 170-200 mm end position for high-force pressing applications without adding external mechanical stops.
Product Changeovers
Quickly adjust the stroke length on automated lines when switching between product sizes or varying material thicknesses.
Machine Commissioning
Fine-tune the retract end-stop during initial machine setup to perfect timing and avoid costly redesigns.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-30S the Right Cylinder?
Choose this 160 mm bore when a 100 mm cylinder (providing 3927 N push at 0.5 MPa) lacks the force for heavy moving masses, but a 200 mm bore is physically oversized. The adjustable 170-200 mm window is perfect for product changeovers where exact end-position tuning varies per batch. For fixed travel without the adjusting screw, a standard SAI cylinder is simpler, but this SAIJ model saves time during machine setup.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 200 mm stroke, PT tapered port thread, and the -S magnet requirement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 200 mm stroke exceeds 300 mm on smaller bores, side-load is less severe here, but the heavy 40 mm rod still requires an external guide for unsupported loads. For true load holding without air pressure, consider the SAIL or BSAI series instead of relying on the stop screw.
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 SAIJ160BX200-30S 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 can deliver up to 2050 kgf.
The rear adjuster screw allows you to shorten the 200 mm nominal stroke by up to 30 mm, providing a usable travel window of 170 to 200 mm. This stop screw sets the end position but does not lock the load without live air pressure.
