About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-50S
The AirTAC SAIJ32X210-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and features a built-in magnet for CMSE reed and DMSE electronic sensors. The SUS304 stainless steel rod offers high corrosion resistance, making it suitable for demanding environments.
This model features a 210mm nominal stroke that can be fine-tuned backward by up to 50mm, creating a usable travel window of 160-210mm. The external adjusting screw acts purely as a mechanical stop to dial in the end position during commissioning. It does not lock or hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-50S Is Used
End-Position Tuning
Dial in the exact retract distance within the 160-210mm window during machine commissioning without adding external stop blocks.
Product Changeover
Quickly adjust the stroke length on a packaging line when handling different product sizes, saving setup time.
Clamping Force Setup
Fine-tune the clamping travel on workholding fixtures, ensuring the 402N force is applied at the exact required position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-50S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your application requires precise end-position tuning without swapping out physical components. If your process needs less force, stepping down is not an option since 32mm is the smallest SAIJ bore. If you require higher thrust, the 40mm bore offers 628N push force at 0.5 MPa. The PT tapered port thread matches standard pneumatic fittings securely.
When replacing an ISO 15552 cylinder, match the 32mm bore, 210mm stroke, 50mm adjustment range, PT port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface. Because the stroke is 210mm, ensure external guides support the rod to prevent excessive side-load wear, as the 12mm rod diameter has limits on bending stress.
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 SAIJ32BX210-50S FAQ
The rear adjuster screw lets you shorten the effective stroke from 210mm down to as little as 160mm. It acts as a mechanical stop for end-position tuning and is not a lock; the cylinder still requires live air to hold the load.
At 0.5 MPa, it provides 402N of push force and 345N of pull force. The recommended operating speed range is 30-800 mm/s, and it includes a -S magnet for DMSE electronic and CMSE reed sensors.
