About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-30S
The AirTAC SAIJ32X800-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5MPa and features a 12mm SUS304 stainless steel rod. Because this specific SKU carries the -30 adjustment code, its 800mm nominal stroke can be dialed back to create a precise 770-800mm usable travel window. This allows you to fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops.
This model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the sensor grooves on both sides of the extruded aluminum barrel. It uses a PT G1/8 port and offers variable air cushions at both ends to decelerate the load. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-30S Is Used
Machine Changeover
Dial in the 770-800mm retract position during product size changes without physically swapping cylinders or repositioning hard stops.
Long-Stroke Assembly
Handles 800mm extended reach operations where the 30mm adjuster allows final end-position trimming to perfectly seat a component.
Variable End Stops
Ideal for diverter gates on conveyors where the exact 770-800mm travel window must be tweaked on-site to match pallet dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-30S the Right Cylinder?
Choose this 32mm bore when an application requires lighter thrust, stepping down from a 40mm bore that yields 628N at 0.5MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, whereas a fixed SAI cylinder lacks this commissioning flexibility. To replace an ISO 15552 cylinder, match the 32mm bore, 800mm stroke, PT G1/8 port, and the -S magnet.
At an 800mm stroke, the 12mm rod is highly susceptible to side-loading; an external guide rail is strongly recommended to prevent premature seal wear. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. If the machine requires true load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
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 SAIJ32BX800-30S FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7MPa, the push force increases to 563N.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 800mm stroke model, you can shorten the stroke by up to 30mm, creating a usable travel window of 770-800mm. It is a stop, not a lock, and cannot hold a load without live air.
