About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-50
The AirTAC SAIJ160X700-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. With a 700 mm nominal stroke and a 50 mm adjustment range, you can dial back the effective travel to establish a 650-700 mm window without swapping the unit or adding external stops. In the 160 mm bore class, it generates 10053 N of pull force at 0.5 MPa and 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty positioning.
This variant is built with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is not equipped with a magnet for position sensing. The rear adjuster acts purely as a mechanical stop to set the travel end, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-50 Is Used
Heavy-Duty Press Tuning
Dial in the exact 650-700 mm retract position during machine setup to accommodate varying material thicknesses without replacing the cylinder.
Pallet Positioning Stops
Adjust the end-stop on the fly for different pallet sizes on a heavy-load transfer line, using the 50 mm trim window to align stops perfectly.
Large Assembly Jigs
Leverage the 14074 N push force at 0.7 MPa to move heavy fixtures, while fine-tuning the final resting position to match new product dimensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-50 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial thrust—such as the 10053 N pull force at 0.5 MPa—and a variable end-stop for product changeovers. If your process demands less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N of pull. The adjustable stroke is chosen over a fixed SAI cylinder when you need to fine-tune the retract position at commissioning without machining external stop blocks.
Because the stroke is 700 mm, the long unsupported piston rod is susceptible to side-loading; an external guide is highly recommended to prevent premature seal wear. For holding loads safely without live air, this cylinder is not a lock; you should integrate an external pilot-operated check valve or select the SAIL (air-released lock) or BSAI (clamp-lock) variants. To match this ISO 15552 footprint, specify a 160 mm bore, 700 mm stroke, 50 mm adjustment, PT ports, and your required mounting option from the SAIJ subset: 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 SAIJ160AX700-50 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 700 mm nominal stroke by up to 50 mm, creating a 650-700 mm usable travel window. It only sets the end position and does not lock or hold the load without live air pressure.
