About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-20
The AirTAC SAIJ200X210-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 190 to 210 mm, allowing you to dial back the nominal 210 mm stroke by up to 20 mm during commissioning without adding external stops. Delivering 15708 N of push force at 0.5 MPa, it handles heavy actuation tasks while maintaining a standard ISO 15552 mounting footprint.
This variant uses a SUS420J2 stainless steel rod for enhanced durability and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. The rear stopper and variable air cushions manage end-of-stroke deceleration, but neither acts as a lock; for load-holding without live air, consider an external rod lock or AirTAC SAIL series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-20 Is Used
Heavy Press Tuning
Fine-tune the 190-210 mm stroke end-position on heavy presses to accommodate material thickness variations without swapping out the entire cylinder.
Product Changeover
Quickly adjust the rear stopper by up to 20 mm during production line changeovers to handle different product sizes efficiently.
Automated Assembly
Use the 15708 N push force to drive large assembly tooling, relying on the rear screw to set precise retraction limits.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-20 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires up to 15708 N of push force at 0.5 MPa (or 21991 N at 0.7 MPa). If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, saving space and air consumption. The 20 mm rear adjuster is ideal for fine-tuning the end position on product changeovers, whereas a fixed-stroke SAI cylinder is sufficient if your travel distance is permanently set.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 210 mm stroke, 20 mm adjustment, PT port thread, and mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 210 mm, which is relatively short for this large bore, side-load risks are manageable, but an external guide is still recommended for heavy loads.
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 SAIJ200 Adjustable Cylinder SAIJ200AX210-20 FAQ
The rear adjuster acts as a mechanical stop that trims the effective stroke back by up to 20 mm. For the SAIJ200X210-20, this creates a usable travel window between 190 and 210 mm, allowing you to set the exact end position without changing the cylinder.
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
