About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-50S
The AirTAC SAIJ160X600-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 550 to 600 mm. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and because this SKU includes the -S magnet, it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
This model is built with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The integrated rear adjusting screw acts purely as a mechanical stop to fine-tune the retract end position without needing external stops. It is important to note that this adjuster, alongside the standard variable air cushions at both ends, only decelerates the travel; it does not function as a lock to hold the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-50S Is Used
Heavy Press Tuning
Dial in the exact 550 to 600 mm end-stop during heavy press commissioning to accommodate different material thicknesses without machining new spacers.
Pallet Changeover
Adjust the retract position on the fly during production line changeovers to handle varying pallet sizes while leveraging the 10053 N pull force.
Large Fixture Setup
Fine-tune the clamping reach on large automated fixtures, using the PT ported cylinder to establish precise mechanical endpoints before applying full clamping force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-50S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 10053 N pull force at 0.5 MPa and demands on-the-fly end-position tuning during commissioning or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your thrust requirements are lower, stepping down to a 125 mm bore yields 8590 N push at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N. For an exact ISO 15552 replacement match, ensure you specify the 600 mm nominal stroke, 50 mm adjustment range, PT port threads, SUS420J2 rod material, and the -S magnet option.
Because this unit features a 600 mm stroke, the extended M36x2 rod is subject to increased side-loading risks; an external guide mechanism is highly recommended to prevent premature seal wear. Furthermore, if your machinery requires true load-holding capability in the event of air pressure loss, this cylinder will not suffice, and you should instead explore the SAIL air-released lock or BSAI clamp-lock series. The compatible mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ160AX600-50S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 13234 N. At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force.
The rear adjusting screw allows you to mechanically shorten the effective stroke by up to 50 mm, creating a usable travel window of 550 to 600 mm. This screw functions as a travel stop and does not lock the load without live air pressure.
