About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-30
The AirTAC SAIJ32X650-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 650mm nominal stroke by up to 30mm. This creates a precise 620-650mm usable travel window for fine-tuning end positions during commissioning without swapping hardware. It delivers 402N of push force at 0.5MPa and features a SUS304 stainless steel rod for superior corrosion resistance.
The rear adjuster functions strictly as a travel stop to set deceleration, not as a load-holding lock. Because this unit lacks a magnet, external reed or solid-state sensing is not supported without modification. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port provides a tight pneumatic seal.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-30 Is Used
End-Position Tuning
Dial in the exact 620-650mm travel limit during machine commissioning to perfect product handling without machining new hard stops.
Product Changeover
Quickly adjust the rear stopper to accommodate varying package sizes on a packaging line, reducing setup downtime between runs.
Variable Stroke Stops
Set precise retract distances for delicate assembly operations where the standard 650mm stroke would apply too much force or overtravel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-30 the Right Cylinder?
Choose this 32mm bore when an application requires precise variable end-stops and moderate thrust, stepping up to the 40mm bore yields 628N of push force at 0.5MPa for heavier loads. An adjustable stroke is preferred over a fixed SAI cylinder when you need machine setup flexibility or product-size changeover without adding external stops. For drop-in compatibility, match the 32mm bore, 650mm stroke, 30mm adjustment, PT port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface.
Because the 650mm stroke is relatively long for a 32mm rod, it increases susceptibility to side-loading forces; always use an external guide to prevent rod binding and premature seal wear. Remember that a plain SAIJ does not hold its position without live air pressure—if load-holding is required, consider the SAIL or BSAI series instead.
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 SAIJ32BX650-30 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke. For this SAIJ32X650-30 model, you can trim the 650mm nominal stroke back by up to 30mm, giving a usable travel window of 620-650mm for fine-tuning at commissioning.
