About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-75S
The AirTAC SAIJ200X90-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 90 mm stroke by up to 75 mm. This yields a usable travel window of 15-90 mm, providing immense flexibility for product changeovers without physically swapping the cylinder.
This unit features a carbon steel piston rod and PT tapered port threads. Because it includes a magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state sensors housed neatly within the dual-side extruded aluminum barrel grooves. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not hold the load without live air pressure, so applications requiring true load-holding should utilize an external rod lock or explore SAIL and BSAI series variants.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-75S Is Used
Variable Press End-Stop
Dial in the exact 15-90 mm compression distance for delicate assemblies during machine setup, ensuring precise force application without changing hardware.
Product Size Changeover
Quickly adapt automated line stroke lengths to accommodate new product dimensions, using the rear adjuster to fine-tune the retract position on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-75S the Right Cylinder?
Selecting this 200 mm bore adjustable cylinder makes sense when your machine setup requires variable end-stops within a 15 to 90 mm range, bypassing the need to inventory multiple fixed-stroke SAI units. The robust 40 mm rod and M36x2 thread handle significant side loads, though any application approaching the maximum stroke should employ an external guide to prevent premature seal wear.
When specifying an ISO 15552 replacement, match the 200 mm bore, 90 mm nominal stroke, 75 mm adjustment range, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets to streamline your design footprint.
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 SAIJ200X90-75S FAQ
The rear adjusting screw allows you to shorten the 90 mm nominal stroke by up to 75 mm, creating a usable travel window of 15-90 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
