About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-20S
The AirTAC SAIJ160X750-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 18095N at 0.9 MPa, making it suited for heavy-duty operations. The integrated -20 mm adjustment screw allows you to trim the effective travel back, creating a precise 730-750 mm usable window to dial in end positions during commissioning without external stops.
This unit features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for position sensing. Sensors mount neatly into the sensor grooves on both sides of the extruded aluminum barrel, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The PT tapered port threads ensure a tight, reliable pneumatic connection for high-flow demands.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-20S Is Used
Heavy Machinery Setup
Fine-tune the 730-750 mm retraction point on large fabrication presses during initial setup, avoiding the need to machine custom external spacers.
Product Size Changeovers
Quickly adapt automated heavy-duty clamping stations to different pallet widths by dialing the rear adjuster screw rather than replacing the entire actuator.
Material Positioning
Vary the end-stop position for large material handling stops on conveyors, ensuring precise placement of heavy steel or timber loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-20S the Right Cylinder?
Select this 160 mm bore cylinder when an 80 mm bore (yielding 4523N push at 0.9 MPa) cannot meet your force requirements, but a 200 mm bore would be excessive. The adjustable stroke is ideal for product changeovers, letting you shift the 730-750 mm end-stop rapidly instead of physically swapping the cylinder. Because the stroke is 750 mm, the M36x2 rod must be properly supported by an external guide to prevent excessive side-loading and premature seal wear.
This adjustable stopper only sets the travel end and decelerates the load alongside the 50 mm air cushions; it does not hold the load without live air. For dead-air load holding, integrate an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. To match this ISO 15552 footprint exactly, specify the 160 mm bore, 750 mm stroke, PT G3/4 port, -20 adjustment, SUS304 rod, -S magnet, and a mounting choice from Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ160 Adjustable Cylinder SAIJ160BX750-20S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095N and a pull force of 9425N. Its maximum theoretical force at 1.0 MPa is 2050 kgf.
The rear adjuster screw allows you to shorten the 750 mm nominal stroke by up to 20 mm, providing a usable travel window of 730-750 mm. This stopper only limits the travel end and does not lock the load without continuous air pressure.
