About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-100S
The AirTAC SAIJ200X650-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. The built-in -100 adjustment mechanism allows you to dial back the 650mm nominal stroke, creating a precise 550-650mm usable travel window without adding external stops. This profile cylinder features a robust 40mm carbon steel rod and PT tapered ports.
Because this SKU includes the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded barrel grooves. The rear adjuster acts purely as a travel stop for product changeovers, meaning it cannot hold the load safely without live air pressure. For any load-holding requirements, an external pilot-operated check valve or a dedicated SAIL locking cylinder is required.

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 SAIJ200X650-100S Is Used
Heavy Stamping Presses
Dial in the exact 550-650mm end position during die changes, using the rear stopper to accommodate different part heights without replacing the cylinder.
Large Material Diverters
Adjust the retract distance on the fly to handle varying pallet sizes on a heavy-duty conveyor line, ensuring precise routing without external stop blocks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-100S the Right Cylinder?
The adjustable 550-650mm travel window is ideal for machinery processing varying product sizes, allowing operators to fine-tune the retract end position during commissioning rather than swapping out the entire cylinder for a fixed-stroke SAI variant. When integrating this unit, ensure your ISO 15552 mounting choice uses the SAIJ-compatible set: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR configurations are omitted.
Given the 650mm stroke, the 40mm carbon steel rod requires external guidance to prevent excessive side-loading and premature seal wear, despite its large diameter. Operating speed for this bore is 30-500mm/s. Remember that the rear adjuster and the variable air cushions only manage end-of-stroke deceleration; they do not function as a brake, so a BSAI clamp-lock cylinder should be considered if static holding is needed.
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 SAIJ200X650-100S FAQ
At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster allows you to shorten the 650mm nominal stroke by up to 100mm, providing a usable travel window of 550-650mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
