About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-100S
The AirTAC SAIJ63X165-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 63 mm bore generating 2182 N of push force at 0.7 MPa, paired with a generous 100 mm adjustment range. This yields a usable travel window of 65 to 165 mm, allowing precise end-position tuning without swapping hardware. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves.
Built for demanding environments, this unit utilizes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance. It operates at speeds of 30-800 mm/s and uses PT tapered port threads (G3/8). The rear adjuster acts purely as a mechanical stop to fine-tune the retraction point; it does not lock the load, so maintaining position requires continuous air pressure or an external locking device.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-100S Is Used
Product Changeovers
Quickly dial in the retraction point across a 65 to 165 mm window when switching a packaging line to different carton depths, avoiding cylinder swaps.
End-Position Trimming
Fine-tune the stroke during machine commissioning to perfect the seating force of a 2182 N pressing operation without adding external mechanical stops.
Variable Stops
Use the 100 mm rear adjuster to alter the effective travel distance for multi-format assembly stations operating at speeds up to 800 mm/s.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-100S the Right Cylinder?
Choose this 63 mm bore cylinder when an application requires variable end-stops during machine setup or product changeovers, delivering 2182 N push force at 0.7 MPa. If your setup demands less force, stepping down to a 50 mm bore yields 1374 N push at 0.7 MPa. If more thrust is needed, an 80 mm bore provides 3518 N. The wide 100 mm adjustment window makes this SKU ideal for lines running multiple product sizes, replacing the need for fixed-stroke SAI cylinders.
When specifying an ISO 15552 replacement, match the 63 mm bore, 165 mm nominal stroke, 100 mm adjustment code, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). For load-holding without live air pressure, select a SAIL or BSAI cylinder instead of relying on the rear stopper. Because the 165 mm stroke is under 300 mm, side-load stress is moderate, but external guides are still recommended for heavy radial loads.

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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-100S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke by up to 100 mm. This creates a usable travel window of 65 to 165 mm, allowing you to set the exact retraction end-position during commissioning without changing the cylinder.
At 0.7 MPa operating pressure, the SAIJ63X165-100-S generates 2182 N of push force and 1402 N of pull force. It can reach a maximum push force of 2805 N at 0.9 MPa.
