About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-10
The AirTAC SAIJ32X50-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 40 to 50 mm for precise end-position tuning. In this B configuration, it features a SUS304 stainless steel piston rod and PT tapered port threads, making it highly suitable for environments where corrosion resistance is a priority. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups perfectly.
The integrated rear adjusting screw acts as a mechanical stop to dial in the exact retract distance during commissioning, but it does not lock or hold the load without live air pressure. For load-holding requirements, a SAIL or BSAI series cylinder is recommended. This model includes variable air cushions at both ends and operates at speeds between 30 and 800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-10 Is Used
Machine Changeover
Dial in the 40-50 mm travel window during product size changes without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the exact retract distance at commissioning using the rear adjusting screw to perfect the pickup or placement point.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in lab or light-washdown areas where standard carbon steel rods would rust.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-10 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa and a highly specific retract distance within a 40-50 mm window. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force. The adjustable stroke is essential for machine changeovers, allowing you to fine-tune the end stop without swapping the cylinder or adding external physical stops.
When specifying an ISO 15552 replacement, match the 32 mm bore, 50 mm nominal stroke, 10 mm adjustment range, PT port threads, and SUS304 rod material. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found in other series.

- ✓ 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 SAIJ32BX50-10 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 40-50 mm usable travel window. It functions as a mechanical stop for position tuning and does not hold the load without live air pressure.
