About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-20S
The AirTAC SAIJ32X200-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 200 mm stroke back by up to 20 mm, yielding a precise 180-200 mm usable travel window. This bore delivers 402 N of push force at 0.5 MPa, scaling to 724 N at 0.9 MPa. The integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side extruded barrel grooves.
Configured with SUS420J2 stainless steel rod material and PT tapered port threads, this unit uses a 12 mm carbon steel rod with an M10x1.25 thread. The rear adjuster acts purely as a travel stop for commissioning end-position tuning without adding external stops; it does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-20S Is Used
Machine Changeover
Dial in the 180-200 mm travel window during product size changes without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stop at commissioning to absorb mechanical tolerances, ensuring exact positioning using the rear adjustment screw.
Assembly Stations
Accommodate varying part heights on a 32 mm bore line, using the 20 mm trim to adapt the stroke for different component profiles.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-20S the Right Cylinder?
Select this 32 mm bore when an application requires 402 N push force at 0.5 MPa, stepping down from a 40 mm bore that yields 628 N. The 20 mm adjustment window is ideal for product changeovers, allowing you to fine-tune the retract end position without swapping the cylinder. For load-holding without live air, use a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
For ISO 15552 dimensional interchangeability, match the 32 mm bore, 200 mm stroke, 20 mm adjustment, PT G1/8 ports, and -S magnet. Because the 200 mm stroke approaches the threshold requiring external support, ensure the M10x1.25 rod handles the side load or add an external guide to prevent binding.
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 Adjustable Cylinder SAIJ32 SAIJ32AX200-20S FAQ
The rear adjuster screw allows you to shorten the 200 mm nominal stroke by up to 20 mm, creating a 180-200 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
It provides 402 N of push force and 345 N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 724 N.
