About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-100S
The AirTAC SAIJ80X700-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down by up to 100 mm. This creates a highly flexible 600-700 mm usable stroke window, letting you dial in exact end positions during commissioning without swapping out the barrel or adding external stops. It delivers a robust 4523 N of push force at 0.9 MPa and 2268 N of pull force at 0.5 MPa, making it suitable for moving heavy loads.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It is fully compatible with AirTAC CMSE reed switches and DMSE solid-state electronic sensors that mount directly into the extruded aluminum barrel's dual sensor grooves. The PT tapered ports are G3/8, and the cylinder operates at speeds between 30-800 mm/s. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Product Changeover
Rapidly adjust the stroke stopper on automated assembly lines when switching between different product profiles.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-100S the Right Cylinder?
Choose this 80 mm bore when you need significantly more force than the 63 mm version provides (1402 N pull at 0.5 MPa) but want to avoid the bulk of the 100 mm bore. The adjustable stroke is ideal for production lines running multiple product sizes, as the rear stopper lets operators change the retract end position on the fly. Because the stroke is 700 mm, the M20x1.5 piston rod will experience leverage forces under side loads; an external guide is strongly recommended to prevent premature wear.
The rear adjuster acts strictly as a mechanical travel stop and works alongside the variable air cushions at both ends to decelerate the load. It does not hold the load in place without continuous air pressure. If your application requires true fail-safe load holding, you should select a SAIL pneumatic lock cylinder, a BSAI clamp-lock model, or integrate an external rod lock. This SAIJ unit is dimensionally interchangeable per ISO 15552, with a PT port thread and -S magnet configuration.

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 SAIJ80BX700-100S FAQ
At 0.9 MPa, this 80 mm bore cylinder provides 4523 N of push force and 3925 N of pull force. It can deliver a maximum push force of 5027 N at 1.0 MPa.
The rear adjuster screw lets you shorten the 700 mm nominal stroke by up to 100 mm, creating a usable travel window between 600 and 700 mm. It acts as a stop to set the end position and does not lock the load without air pressure.
