About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-100S
The AirTAC SAIJ80X600-100-S is a double-acting ISO 15552 profile cylinder featuring a SUS304 stainless steel rod and a rear stroke adjuster. By turning the external stopper screw, you can trim the effective travel back by up to 100 mm, creating a precise 500-600 mm usable stroke window without swapping out the barrel. This on-the-fly tuning is ideal for product changeovers or dialing in exact end positions during machine commissioning.
Delivering 4523 N of push force at 0.9 MPa, this 80 mm bore profile cylinder integrates seamlessly with ISO 15552 mounting dimensions. It features PT tapered ports, variable air cushions at both ends, and a magnetic piston for electronic DMSE or reed CMSE sensor tracking. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-100S Is Used
Variable Product Changeover
Adjust the 500-600 mm stroke window on the fly to handle different package sizes on a packaging line without changing out the cylinder.
Commissioning End-Tuning
Dial in the exact retract position during machine setup, using the 100 mm rear stopper screw to fine-tune the end position without external shims.
High-Force Positioning
Leverage the 4523 N push force at 0.9 MPa to move heavy fixtures, while relying on the adjustable stop to set precise machining endpoints.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-100S the Right Cylinder?
Choose this 80 mm bore when your application demands high thrust but requires variable end-stop positioning, stepping up from a 63 mm bore that provides 2805 N at 0.9 MPa. The 100 mm adjustment range is perfect for accommodating multiple product sizes on a single conveyor line without bolting on external stops. If you need a fixed stroke instead, the standard SAI series is the direct equivalent.
Because the 600 mm stroke is substantial, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading and rod binding. Remember that the rear adjuster is a stop, not a lock; if your machine requires true load-holding without live air, select the SAIL or BSAI series instead. Mounting options for this profile cylinder include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX600-100S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the nominal 600 mm stroke by up to 100 mm, giving you a usable travel window of 500-600 mm. It allows you to fine-tune the retract end position at commissioning without replacing the cylinder.
At an operating pressure of 0.9 MPa, the SAIJ80X600-100-S provides 4523 N of push force and 4071 N of pull force. It operates at speeds between 30 and 800 mm/s.
