About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-50
The AirTAC SAIJ32X185-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 185 mm stroke that can be dialed back by up to 50 mm, yielding a usable travel window of 135 to 185 mm. This built-in stopper allows for precise end-position tuning during commissioning without adding external stops. Delivering 402 N of push force at 0.5 MPa, it uses a G1/8 port and a 12 mm rod. The barrel is extruded aluminum with sensor grooves on both sides.
This variant features an SUS304 stainless steel rod (option B) for superior corrosion resistance. It uses a PT tapered port thread and lacks a piston magnet. The rear adjuster acts purely as a travel stop to set deceleration endpoints; it does not hold the load without live air pressure. For load-holding needs, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-50 Is Used
Product Changeovers
Dial in the exact 135 to 185 mm travel needed for different product sizes on a packaging line without swapping out the entire cylinder assembly.
Commissioning Fine-Tuning
Precisely set the retract end-position during machine setup to perfect pick-and-place alignment, avoiding the need for external mechanical stops.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in food processing or light chemical handling where rust prevention is critical.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-50 the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa and a highly variable stroke endpoint. If your setup needs less force, stepping down is not an option within the SAIJ line, but stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa for heavier payloads. The 50 mm adjustment range is ideal for machines that undergo frequent product-size changeovers, eliminating the need to physically swap cylinders to achieve a shorter reach.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 185 mm nominal stroke, 50 mm adjustment, PT port thread, and SUS304 rod material. Note that SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Because the 185 mm stroke is under 300 mm, external side-load guides are less critical, though the 12 mm rod still handles moderate side loads better than smaller variants.

- ✓ 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 SAIJ32BX185-50 FAQ
At 0.5 MPa, 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. It operates at speeds ranging from 30 to 800 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 185 mm nominal stroke down to 135 mm. This stop only sets the travel end and does not lock the load without continuous air pressure.
