About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-30
The AirTAC SAIJ63X195-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 165-195 mm usable travel window. Delivering 1559 N of push force at 0.5 MPa, it provides robust actuation for mid-range industrial tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches.
This variant utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. The rear stopper screw allows precise end-position tuning at commissioning without adding external stops or swapping the cylinder. It features PT tapered port threads (G3/8) and variable air cushions at both ends to manage deceleration.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-30 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 165 and 195 mm during machine setup, eliminating the need to physically swap cylinders for minor length corrections.
Product Changeover Tuning
Quickly adjust the stroke end to accommodate new product sizes on a conveyor line without disassembling the actuator mounting block.
Mid-Force Assembly Actuation
Leverage the 1559 N push force at 0.5 MPa to drive pressing and clamping operations that require precise depth control at the end of travel.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-30 the Right Cylinder?
Choose this 63 mm bore when 50 mm (982 N push @0.5 MPa) lacks the power to move your load, but stepping up to 80 mm (2513 N) would oversize the system and consume excess air. The 30 mm adjustment range is ideal for product changeovers on a line, letting you dial back the 195 mm stroke to a precise 165 mm end-stop on the fly. For strokes of 195 mm, side-load is moderate, but always guide the load externally if unsupported.
Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. If your application requires true fail-safe load holding, select the SAIL air-released lock or BSAI clamp-lock cylinder instead. This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.

- ✓ 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 SAIJ63AX195-30 FAQ
It features a rear stopper screw that lets you mechanically shorten the effective stroke by up to 30 mm. This creates a usable travel window of 165-195 mm, allowing you to fine-tune the end position without changing the cylinder.
At 0.5 MPa operating pressure, it provides 1559 N of push force and 1402 N of pull force. The maximum operating pressure is 1.0 MPa.
