About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-10S
The AirTAC SAIJ63X200-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 190-200 mm usable travel window, allowing you to dial back the 200 mm nominal stroke by up to 10 mm. Delivering 1559 N of pull force at 0.5 MPa, it handles mid-range automation tasks with precision.
This variant includes a SUS420J2 stainless steel rod and a magnet for position sensing. It supports AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side barrel grooves. The rear adjuster acts purely as a mechanical stop for end-position tuning, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-10S Is Used
Machine Commissioning
Fine-tune the 190-200 mm retract end-stop during setup to align tooling perfectly without machining external spacers.
Product Changeover
Quickly adjust the retract position by up to 10 mm when running a slightly shorter product variant on the same line.
Assembly Stations
Utilize the 1559 N pull force and CMSE/DMSE sensor feedback to verify part seating at the adjusted travel end.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX200-10S the Right Cylinder?
Choose this 63 mm bore when you need 1559 N pull force at 0.5 MPa, stepping down from the 80 mm bore (2268 N pull) for a lighter footprint, or up from the 50 mm bore (825 N pull) for higher thrust. The 10 mm adjustment window is perfect for fine-tuning retract positions during machine commissioning without adding external stops. For drop-in compatibility, match the 63 mm bore, 200 mm stroke, PT tapered G3/8 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. If you need true load-holding without air pressure, use a SAIL or BSAI cylinder instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ63AX200-10S FAQ
The rear adjuster screw lets you shorten the 200 mm nominal stroke by up to 10 mm, creating a 190-200 mm travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
At 0.5 MPa, it provides 1559 N pull force and 2182 N push force. The -S suffix indicates an integrated magnet compatible with AirTAC CMSE reed and DMSE electronic sensors mounted in the profile grooves.
