About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-40S
The AirTAC SAIJ32X200-40-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that trims the effective stroke. With a 200 mm nominal stroke and a 40 mm adjustment range, you get a usable travel window of 160 to 200 mm for precise end-position tuning at commissioning. It delivers 402 N of push force at 0.5 MPa and utilizes a SUS304 stainless steel rod for enhanced corrosion resistance.
This model includes a piston magnet for position sensing via CMSE reed or DMSE electronic switches. The PT tapered G1/8 port and M10x1.25 rod thread handle standard 32 mm bore loads, but remember the rear adjuster acts only as a travel stop, not a lock, so live air is required to hold position.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-40S Is Used
Changeover Adjustment
Dial in the 160-200 mm travel window during machine setup to accommodate new product lengths without physically swapping cylinders.
End-Stop Tuning
Fine-tune the final retract position within 40 mm to perfect a pressing or clamping operation during commissioning.
Variable Diverting
Adjust the stroke length on a conveyor diverter to handle different package sizes on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-40S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, stepping up from a smaller unit or down from a 40 mm bore that provides 628 N. The 40 mm adjustable window is ideal for product changeovers, allowing you to dial in the exact end-stop without swapping the cylinder or adding external stops. For strokes of 200 mm, the M10 rod handles moderate side loads, but always guide long movements externally.
To match this ISO 15552 footprint, specify a 32 mm bore, 200 mm stroke, 40 mm adjustment, PT G1/8 ports, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the rear adjuster cannot hold loads without air pressure, use an SAIL or BSAI cylinder if true locking is required.
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 SAIJ32BX200-40S FAQ
It provides a push force of 402 N and a pull force of 345 N at 0.5 MPa. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 200 mm nominal stroke to any effective length between 160 and 200 mm. It is a travel stop, not a lock, so it cannot hold the load without live air pressure.
