About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-50S
The AirTAC SAIJ32X950-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 950 mm stroke that can be dialed back by up to 50 mm, yielding a usable travel window between 900 and 950 mm. This allows precise end-position tuning at commissioning without swapping out the physical cylinder. Delivering 402 N of push force at 0.5 MPa, it features a SUS304 stainless steel rod and a PT tapered port.
Because the stroke extends to 950 mm on a 32 mm bore, the 12 mm rod requires external guidance to prevent excessive side-loading and premature seal wear. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works directly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-50S Is Used
Product Changeovers
Dial in the 900-950 mm retract position during format size changes on a packaging line without replacing the actuator.
Adjustable Diverting
Fine-tune the end-stop distance on a sorting pusher to accommodate varying box lengths on the fly.
Machine Setup
Trim the effective stroke by up to 50 mm during commissioning to perfectly time a slow approach to a delicate workpiece.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-50S the Right Cylinder?
Choose this 32 mm bore when your application requires roughly 402 N of push force at 0.5 MPa; step up to a 40 mm bore if you need 628 N, or down to a smaller profile if your load is lighter. The adjustable stroke is ideal for product changeovers, letting you shift the retract end-stop by up to 50 mm without adding external stops. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
For any stroke length of 300 mm or more, an external guide is strongly recommended to support the load and protect the piston rod. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder cannot hold a load without live air. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ32BX950-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm, creating a usable travel window of 900 to 950 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
