About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-100S
The AirTAC SAIJ63X195-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the effective travel within a 95-195 mm window. Delivering 1402 N of pull force at 0.5 MPa, it handles demanding changeover tasks without requiring external stops. This variant incorporates a SUS420J2 stainless steel rod for improved corrosion resistance and utilizes PT tapered port threads.
Equipped with a standard magnet (-S), the barrel is designed to support AirTAC CMSE reed and DMSE solid-state electronic sensors seamlessly via the dual-side sensor grooves. The rear adjuster functions purely as a travel stop to set end-position deceleration, meaning it will not hold a load safely without continuous live air pressure. For load-holding requirements without supply pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-100S Is Used
Variable End-Stop Positioning
Dial in precise retract distances from 95 to 195 mm during machine setup, allowing quick adaptation to different material thicknesses without physically changing the cylinder.
Product Size Changeover
Ideal for packaging lines that frequently switch between different carton or part dimensions, using the rear stopper to instantly set new end-of-stroke positions.
Corrosion-Resistant Actuation
The SUS420J2 stainless steel rod provides an extra layer of defense against minor moisture and environmental exposure in standard industrial manufacturing cells.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-100S the Right Cylinder?
Selecting this 63 mm bore cylinder over a smaller 50 mm option provides a significant thrust upgrade, pushing from 982 N up to 1559 N at 0.5 MPa. The 100 mm adjustment range is ideal for machines processing variable product sizes, allowing operators to dial in the exact end-stop position during commissioning rather than swapping out fixed-stroke SAI cylinders.
When specifying a replacement, verify the 63 mm bore, 195 mm stroke, 100 mm adjuster, PT G3/8 ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on some standard ISO 15552 lines. Because the total stroke is under 300 mm, side-load risks are moderate, but the 20 mm rod diameter still requires external guiding for heavy radial loads.
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 SAIJ63AX195-100S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. It can reach a maximum push force of 2805 N at 0.9 MPa.
The rear adjuster acts as an external stopper that lets you mechanically shorten the 195 mm nominal stroke by up to 100 mm, creating a usable travel window of 95 to 195 mm. It sets the end position but does not lock the load without live air pressure.
