About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-100S
The AirTAC SAIJ80X500-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 500 mm travel by up to 100 mm for a precise 400-500 mm usable window. Built with a SUS304 stainless steel rod, it delivers 2513 N of push force at 0.5 MPa, making it robust enough for heavy positioning tasks.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, utilizing the standard extruded aluminum barrel with sensor grooves on both sides. The rear stopper acts purely as a travel end-point tuner for product changeovers, not a load lock, meaning live air is required to hold position. It supports a speed range of 30-800 mm/s and features PT tapered ports sized at G3/8.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-100S Is Used
Variable Length Machining
Fine-tune the 400-500 mm stroke window on the fly to accommodate different material lengths during production changeovers without external stops.
Product Diversion Setup
Adjust the retract position precisely during commissioning to align pusher arms with varying package sizes on a packaging line.
Heavy Load Positioning
Leverage the 2513 N push force at 0.5 MPa to move heavy pallets, using the rear screw to dial in the exact stopping point safely.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX500-100S the Right Cylinder?
Select this 80 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is underpowered but a 100 mm bore (3927 N) is physically oversized. The 100 mm adjustment window is ideal for machinery processing varying product lengths, letting you fine-tune the retract end-position without swapping hardware. Because the nominal stroke is 500 mm, an external guide is recommended to prevent excessive side-loading on the rod.
For an exact ISO 15552 replacement, match the 80 mm bore, 500 mm stroke, 100 mm adjuster, PT G3/8 ports, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your application requires holding the load without continuous air pressure, use an external rod lock or pilot-operated check valve, as the SAIJ adjuster and air cushions do not function as brakes.
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 SAIJ80 Adjustable Cylinder SAIJ80BX500-100S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the nominal 500 mm, providing a usable travel window of 400 to 500 mm. This stopper only sets the end position and does not lock the load without live air.
