About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-30
The AirTAC SAIJ32X950-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down to 920 mm from its 950 mm nominal length. Delivering 402 N of push force at 0.5 MPa, this extruded aluminum body unit features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-800 mm/s. It uses a PT tapered port thread and includes adjustable air cushions at both ends to manage deceleration.
Because the stroke extends to 950 mm on a 32 mm bore, the 12 mm diameter rod and M10x1.25 rod thread are highly susceptible to side-loading, meaning an external guide rail is essential to prevent binding. The rear stopper mechanism allows precise end-position tuning during commissioning without adding external physical stops, though it acts strictly as a travel limiter and does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-30 Is Used
Long-Reach Diversion
Dial in the 920-950 mm stroke to perfectly align a diverter arm on a wide conveyor belt during initial installation without machining new hard stops.
Product Changeover
Quickly adjust the end-of-stroke position by up to 30 mm to accommodate different package lengths on a packaging line.
Extended Assembly Press
Utilize the SUS304 rod and long travel for a corrosion-resistant, fine-tuned pressing action in extended-stroke assembly stations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-30 the Right Cylinder?
Choose this specific 32 mm bore cylinder when an application requires a long 920-950 mm travel window but demands exact end-position tuning at setup; if you need greater thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. An adjustable stroke is favored over a fixed SAI model when accommodating slight mechanical variances or product changeovers on a line.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 950 mm stroke, 30 mm adjustment range, PT port thread, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that SAIJ omits FB, CA, CB, and CR mounts. Given the 950 mm length, always support the load with an external linear guide to prevent rod deflection. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead.

- ✓ 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 SAIJ32BX950-30 FAQ
At 0.5 MPa operating pressure, 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 acts as a mechanical stopper, allowing you to shorten the effective travel from 950 mm down to a minimum of 920 mm. It sets the end position but does not lock the load without live air pressure.
