About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-20S
The AirTAC SAIJ200X210-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 190 to 210 mm. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for position feedback.
This variant features a SUS420J2 stainless steel rod and a built-in magnet compatible with CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position during commissioning without adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-20S Is Used
Heavy Press Tuning
Dial in the exact 190-210 mm retract stop during heavy press commissioning to accommodate material thickness variations without external stopper blocks.
Product Changeover
Quickly adjust the end-of-stroke position on a 200 mm bore assembly line when switching between product sizes, saving downtime on physical cylinder swaps.
Large Clamp Positioning
Fine-tune the clamping travel on large industrial fixtures where the 15708 N push force at 0.5 MPa is required, using the rear screw for precise material contact.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX210-20S the Right Cylinder?
Select this 200 mm bore cylinder when your application requires up to 15708 N of push force at 0.5 MPa, or step down to the 160 mm bore if you only need 10053 N. The adjustable 190-210 mm window is ideal for dialing in exact end positions during machine setup or product changeover, avoiding the need to swap a fixed-stroke SAI cylinder.
Because the stroke is 210 mm, ensure external guiding is used to handle side loads, as even the robust 40 mm rod and M36x2 thread cannot support high lateral forces alone. The PT tapered ports and mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2) follow the ISO 15552 interface. Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air, use a SAIL or BSAI cylinder.
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 SAIJ200AX210-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm, giving a usable travel window of 190 to 210 mm. It allows fine-tuning of the end position at commissioning without swapping the cylinder, but it is a stop, not a lock, and requires live air to hold the load.
At 0.5 MPa, this cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
