About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-20
The AirTAC SAIJ200X60-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a robust 200mm bore generating 15708N of push force at 0.5MPa and a 60mm nominal stroke. Equipped with a rear stroke adjuster, this model allows you to dial back the travel by up to 20mm, creating a highly precise 40-60mm usable stroke window. This eliminates the need to swap cylinders or bolt on external stops during commissioning or product changeovers.
This variant is configured with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE electronic solid-state sensors. The 40mm cushion length at both ends helps absorb the substantial kinetic energy of this high-thrust unit. Remember that the rear adjuster acts solely as a travel stop to set deceleration, not as a lock; it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-20 Is Used
Heavy Pressing Operations
Delivers 15708N of raw thrust at 0.5MPa for assembly operations, with the 40-60mm travel window allowing operators to fine-tune the exact bottoming depth on the fly.
Machine Setup & Changeover
The rear stopper screw lets production lines quickly adjust the end-position for different product sizes without physically replacing the ISO 15552 cylinder.
High-Force End-Stop Tuning
Ideal for heavy industrial automation where the 20mm adjustment range compensates for mechanical wear or slight misalignments during initial commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-20 the Right Cylinder?
Selecting the SAIJ200X60-20 is ideal when your machinery demands extreme force alongside variable end-stops. If you need slightly less thrust, stepping down to a 160mm bore yields 10053N of push force at 0.5MPa. However, for heavy pressing or holding tasks at 200mm bore, this cylinder provides up to 3204kgf at 1.0MPa. Choose this adjustable-stroke model over a fixed SAI cylinder when you need on-the-fly commissioning fine-tuning without mechanical modifications. Because the stroke is relatively short at 60mm, side-loading risks are minimized, but you should still ensure rigid mounting using the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 interfaces. For load-holding without live pressure, this cylinder is not suitable; instead, specify an AirTAC SAIL or BSAI locking cylinder.

- ✓ 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 SAIJ200AX60-20 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum operating pressure of 1.0MPa, it can deliver up to 3204kgf.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 20mm. This creates a usable travel window of 40-60mm, allowing precise end-position tuning without changing the cylinder.
