About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-50
The AirTAC SAIJ32X950-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the travel by up to 50 mm. This yields a usable end-position window of 900 to 950 mm, ideal for fine-tuning machinery setup without external stops. It delivers 402 N of push force at 0.5 MPa and uses a G1/8 port.
Built with a SUS304 stainless steel rod, this unit handles corrosive environments better than standard carbon steel. The extruded aluminum barrel features sensor grooves on both sides, though this specific SKU omits the magnet, so external sensors will not detect piston position. The rear adjuster acts purely as a travel stop for deceleration and positioning, not as a lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-50 Is Used
Machine Changeover
Dial in the 900-950 mm stroke window during product line changeovers without swapping cylinders or adding external mechanical stops.
Extended Transfer Lines
Provides reliable 402 N push force over a 950 mm travel distance, with an external guide recommended to handle side-load on the long rod.
Corrosive Environment Actuation
The SUS304 stainless steel rod withstands moisture and washdowns while providing precise end-stop tuning for automated processing equipment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-50 the Right Cylinder?
Choose this 32 mm bore when an application requires moderate force (402 N push at 0.5 MPa) and exact end-position tuning over a long 900-950 mm window. If your setup needs greater thrust, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. Because the stroke is 950 mm, the 12 mm rod and M10x1.25 thread will experience significant side-loading if the load is unsupported; an external guide rail is strongly recommended to prevent premature seal wear.
The adjustable rear screw is selected over a fixed SAI cylinder when you need commissioning flexibility or frequent product-size changeovers. Note that the rear adjuster and air cushions do not hold the load without live air pressure; for true pneumatic locking, consider the SAIL or BSAI series. This unit uses PT tapered port threads and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ32BX950-50 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 the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
A rear adjusting screw acts as a travel stop, allowing you to mechanically shorten the 950 mm nominal stroke by up to 50 mm. This creates a 900-950 mm usable travel window for fine-tuning at commissioning. The adjuster is a stop only and does not lock the load without live air pressure.
