About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-75S
The AirTAC SAIJ200X475-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 400 to 475 mm. The integrated -S magnet enables precise position detection, working seamlessly with AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-sided barrel grooves.
This unit utilizes a robust 40 mm carbon steel rod and M36x2 thread, designed to handle significant side loads, though its 475 mm length still necessitates an external guide to prevent rod binding. The rear stopper screw allows you to dial back the stroke by up to 75 mm during commissioning without swapping the cylinder or adding external stops. It features PT tapered port threads and adjustable air cushions at both ends to decelerate heavy loads smoothly.

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 SAIJ200X475-75S Is Used
Heavy Press Tuning
Dial in the exact 400-475 mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stopper hardware.
Pallet Positioning
Adjusts the retract end-position on the fly for different pallet sizes on a transfer line, ensuring precise stops for large payloads.
Machine Changeover
Speeds up product changeovers by allowing operators to trim up to 75 mm of stroke directly at the rear screw instead of swapping out the entire cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-75S the Right Cylinder?
Selecting this 200 mm bore over a smaller 160 mm neighbor steps the thrust up from 10053 N to 15708 N at 0.5 MPa, ensuring reliable motion for massive payloads. An adjustable stroke is chosen over a fixed SAI cylinder when a machine requires variable end-stops for product changeovers, allowing you to fine-tune the 75 mm travel window on the fly. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series instead.
To replace an ISO 15552 cylinder with this SAIJ model, match the 200 mm bore, 475 mm nominal stroke, 75 mm adjustment range, and G3/4 port size. Confirm the mounting interface uses the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), and specify the -S magnet for CMSE/DMSE sensor compatibility. Because the 475 mm stroke is substantial, always incorporate an external guide rail to manage side-load forces and prevent premature wear on the 40 mm carbon steel rod.

- ✓ 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 SAIJ200X475-75S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers 3204 kgf. The operating speed ranges from 30 to 500 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm, creating a usable travel window of 400 to 475 mm. It is a travel stop only and does not lock or hold the load without continuous air pressure.
