About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-100
The AirTAC SAIJ160X700-100 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It features a rear mechanical adjuster that allows you to fine-tune the effective stroke within a 600 to 700 mm window, providing precise end-position control without swapping out the entire actuator. Driven by a 160 mm bore, it delivers substantial thrust up to 18095 N at 0.9 MPa, while the SUS420J2 stainless steel rod offers excellent corrosion resistance and durability.
This model is equipped with PT tapered ports (G3/4) and variable air cushions at both ends to manage kinetic energy. It is important to note that the rear adjuster acts purely as a travel stop and does not lock the load; for position holding without live air pressure, an external rod lock or a SAIL/BSAI series cylinder is required. The extruded aluminum barrel includes sensor grooves on both sides, allowing for straightforward integration of CMSE reed or DMSE electronic switches when a magnet is specified.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-100 Is Used
Heavy Press Tuning
Dial in the exact 600 to 700 mm end-stop during setup to accommodate varying material thicknesses in large-scale metal forming operations.
Pallet Changeover
Adjust the retract position on the fly to handle different pallet sizes on a heavy-duty transfer line without changing out actuator hardware.
Large Assembly Jigs
Leverage the 18095 N push force at 0.9 MPa to move massive structural components, fine-tuning the stroke to seat parts precisely.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-100 the Right Cylinder?
Selecting the SAIJ160X700-100 is ideal when a machine requires exact end-position tuning during commissioning or frequent product-size changeovers. If the 10053 N push force at 0.5 MPa from a 160 mm bore is insufficient, stepping up to a 200 mm bore yields 15708 N at the same pressure. Conversely, if the system is overpowered, dropping to a 125 mm bore provides 6136 N. Because this actuator features a 700 mm stroke, the 40 mm diameter carbon steel rod is subject to significant side loads; an external guide mechanism must be used to prevent rod binding and premature seal wear.
When replacing an ISO 15552 cylinder, verify the 160 mm bore, 700 mm stroke, 100 mm adjustment range, PT port threads, and the required mounting style. The SAIJ series supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that FB, CA, CB, and CR mounts are omitted from this adjustable variant. This model does not include a magnet (-S), so position sensing requires a compatible external setup or a different SKU.

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 SAIJ160AX700-100 FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At 0.9 MPa, the push force increases to 18095 N. The maximum allowable operating pressure is 1.0 MPa, yielding a maximum push force of 2050 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 700 mm stroke by up to 100 mm, creating a usable travel window of 600 to 700 mm. It only sets the end position and does not hold the load without continuous air pressure.
