Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-10
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 325mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-10
The AirTAC SAIJ32X325-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 325 mm nominal stroke that can be dialed back by up to 10 mm, creating a precise 315-325 mm usable travel window for fine-tuning end positions at commissioning. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and features PT tapered port threads.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during product changeovers. The rear adjuster acts strictly as a travel stop and deceleration aid alongside the variable air cushions—it does not hold the load without live air pressure. For position holding without continuous air, an external rod lock or SAIL cylinder is required. Because the stroke exceeds 300 mm, an external guide is recommended to manage side loads on the 12 mm rod.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-10 Is Used
Machine Setup Tuning
Dial in the exact 315-325 mm end position during initial commissioning without swapping out the entire cylinder or adding shims.
Product Changeover
Quickly adjust the stroke by up to 10 mm to handle slightly different package sizes on a packaging line.
Variable End-Stop
Use the rear stopper screw to fine-tune the retract position for delicate picking and placing operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-10 the Right Cylinder?
Choose this 32 mm bore model when an application requires 402 N of push force at 0.5 MPa with exact end-position tuning. If your process demands greater thrust, stepping up to the 40 mm bore yields 628 N, while dropping to a smaller frame reduces capacity. The SAIJ32X325-10 is selected over a fixed-stroke SAI cylinder when a machine setup requires a variable end-stop to accommodate minor product size changes without mechanical rework.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 325 mm stroke, 10 mm adjustment range, PT port threads, and standard mounting interface. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. As specified, this configuration uses a SUS304 rod and lacks a magnet for sensors. For strokes of 325 mm or longer, always support the load with an external guide rail to prevent rod bending, as the 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 SAIJ32BX325-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the 325 mm nominal stroke by up to 10 mm, providing a usable travel window of 315 to 325 mm. The adjuster acts as a mechanical stop and does not function as a lock to hold the load without air pressure.
