About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-20S
The AirTAC SAIJ32X240-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 220-240 mm usable travel window, allowing you to dial back the 240 mm nominal stroke by up to 20 mm during machine commissioning without swapping out the unit. Built with a 32 mm bore, it delivers 402 N of push force at 0.5 MPa and reaches speeds of 30-800 mm/s.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. It uses a PT tapered G1/8 port and offers adjustable air cushions at both ends to fine-tune end-of-stroke deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-20S Is Used
Machine Changeover
Quickly fine-tune the end-of-stroke position by up to 20 mm during product size changes without replacing the cylinder or adding external stops.
Component Seating
Dial in the exact 220-240 mm travel window needed to seat delicate parts precisely, preventing crushing by adjusting the retract position.
Assembly Line Setup
Use the rear stopper to set variable end-stops during initial commissioning, ensuring perfect alignment before locking down the process.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-20S the Right Cylinder?
Choose this 32 mm bore model when your application requires 402 N of push force at 0.5 MPa. If your process demands less force, stepping down to a 25 mm bore might be an option, but if you need higher thrust, moving up to a 40 mm bore provides 628 N. The adjustable stroke is ideal for applications requiring variable end-stops or fine-tuning at changeover, which is more efficient than installing a fixed-stroke SAI cylinder and adding external shims. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 240 mm stroke, 20 mm adjustment range, PT G1/8 port, and the -S magnet. Because the stroke is 240 mm, ensure external guides are used to prevent excessive side-loading on the M10x1.25 rod thread. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ32BX240-20S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the 240 mm nominal stroke by up to 20 mm, creating a usable travel window of 220-240 mm. This stopper only limits the travel end and does not lock or hold the load without continuous air pressure.
