Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 60mm 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 SAIJ200 Adjustable Cylinder SAIJ200AX60-40S
The AirTAC SAIJ200X60-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It provides a usable travel window of 20 to 60 mm by allowing you to dial back the 60 mm nominal stroke by up to 40 mm during commissioning. In this high-thrust class, it delivers 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to a maximum output of 3204 kgf at 1.0 MPa.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side barrel grooves. The rear adjuster acts purely as a travel stop to fine-tune the end position without adding external stops, but it does not hold the load without live air pressure. For position-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40S Is Used
Press Height Tuning
Dial in the exact 20 to 60 mm travel distance during machine commissioning to set precise forming or pressing depths without swapping cylinders.
Product Size Changeover
Quickly retract the end stop by up to 40 mm when a production line switches to a different product variant, minimizing tooling downtime.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa for heavy-duty clamping or lifting tasks that require exact end-of-stroke positioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40S the Right Cylinder?
Select this 200 mm bore cylinder when your application requires extreme thrust combined with variable end-position tuning, such as setting up different press heights on a production line. If you need less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, but this SAIJ200X60-40-S provides the maximum 15708 N at 0.5 MPa. The adjustable travel is ideal for machine changeovers where a fixed-stroke SAI cylinder would require physical shimming.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 60 mm stroke, 40 mm adjustment range, PT tapered ports, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, explicitly omitting the FB, CA, CB, and CR styles. Although the stroke is short, the heavy 40 mm rod diameter and M36x2 thread handle substantial side loads, yet an external guide is still recommended for optimal bearing life.

- ✓ 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 SAIJ200 Adjustable Cylinder SAIJ200AX60-40S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it delivers a peak output of 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 60 mm nominal stroke by up to 40 mm, creating a usable travel window of 20 to 60 mm. It only sets the end position and does not lock the load without live air pressure.
