About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-50S
The AirTAC SAIJ100X130-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 50 mm adjustment range, creating a usable travel window between 80 mm and 130 mm. Delivering 3927 N of push force at 0.5 MPa, it is built with an SUS420J2 stainless steel rod (option A) for superior corrosion resistance. The integrated magnet (-S) supports position sensing with AirTAC CMSE reed and DMSE electronic switches.
This model uses a PT tapered port thread and includes variable air cushions at both ends to decelerate heavy 100 mm bore loads. The extruded aluminum barrel features dual sensor grooves for flexible switch mounting. The rear adjuster acts purely as a travel stop to fine-tune the end position during commissioning without adding external stops; it does not lock the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-50S Is Used
Machine Setup & Changeover
Dial in the exact retract distance from 80 to 130 mm during product line changeovers without swapping cylinders or adding external stopper blocks.
Variable End-Stop Positioning
Fine-tune the final end position on heavy machinery at commissioning, using the rear adjuster to compensate for mechanical tolerances.
Corrosion-Resistant Actuation
Leverage the SUS420J2 stainless steel rod and 3927 N of thrust in manufacturing environments where moisture or minor corrosive elements are present.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-50S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust (3927 N push at 0.5 MPa) alongside flexible end-position tuning. If you need less force, stepping down to an 80 mm bore yields 2513 N push, whereas moving up to 125 mm provides 6136 N. Select the SAIJ adjustable-stroke design over a fixed SAI model when you need to dial in the exact retract distance during machine setup or product changeover. To match this ISO 15552 interchangeable cylinder, specify: 100 mm bore, 130 mm stroke, 50 mm adjustment, PT ports, and the -S magnet option. Note that the rear screw stop and air cushions only manage travel end deceleration; for true load-holding without live air, use an SAIL (air-released lock) or BSAI (clamp-lock) cylinder.
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 SAIJ100 Adjustable Cylinder SAIJ100AX130-50S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster allows you to trim the effective stroke by up to 50 mm. This creates a usable travel window between 80 mm and 130 mm, letting you set the exact end position during commissioning. The adjuster is a mechanical stop, not a lock, so it will not hold the load without live air pressure.
