About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-30S
The AirTAC SAIJ32X50-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 50 mm travel by up to 30 mm, creating a highly versatile 20-50 mm usable stroke window. Delivering 345 N of pull force at 0.5 MPa, it is equipped with a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for CMSE reed and DMSE electronic sensors.
Unlike a fixed-stroke SAI cylinder, this model lets you fine-tune the retract end-position at commissioning without swapping the barrel or adding external stops. The rear adjuster acts purely as a travel stop and works alongside the variable air cushions at both ends to decelerate the rod; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-30S Is Used
Machine Setup Tuning
Dial in the exact 20-50 mm retract position during commissioning to align stamping or pick-and-place heads without machining external spacers.
Product Changeover
Quickly adapt the end-stop distance on a packaging line when switching between different carton sizes, leveraging the 30 mm adjustment range.
Precision End-Positioning
Use the fine rear screw adjustment to set precise lower-limit travel for delicate assembly tasks, relying on the stop rather than repositioning the entire cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-30S the Right Cylinder?
Choose this 32 mm bore when an application requires precise variable end-stops within a 20-50 mm travel window and moderate force (345 N pull at 0.5 MPa). If your setup demands higher thrust, stepping up to the 40 mm bore yields 528 N of pull force at 0.5 MPa.
The SUS304 rod and PT tapered ports are standard here, but the defining feature is the adjustability. Because the SAIJ series omits the FB, CA, CB, and CR mounts, it utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) to maintain its ISO 15552 dimensional interchangeability. Remember that the rear screw is a stop, not a lock; if you need to hold a load without continuous air pressure, use an external pilot-operated check valve.
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 SAIJ32BX50-30S FAQ
The nominal stroke is 50 mm, but the rear adjuster allows you to shorten the effective travel by up to 30 mm, resulting in a usable stroke window of 20-50 mm.
At 0.5 MPa operating pressure, the 32 mm bore 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.
