Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100S
The AirTAC SAIJ100X500-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and provides a usable travel window of 400 to 500 mm, letting you dial back the stroke by up to 100 mm. The barrel is extruded aluminum with sensor grooves on both sides, and because this unit includes the -S magnet, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
A defining advantage of this configuration is the ability to fine-tune the retract end-position during commissioning or product changeover without swapping the cylinder or bolting on external stops. The rear adjuster acts purely as a travel stop to set the deceleration point alongside the variable air cushions at both ends; it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100S Is Used
Variable End-Stop Positioning
Ideal for machining fixtures where the retract position must be shifted by up to 100mm to accommodate different raw material lengths without changing the cylinder.
Machine Setup & Changeover
Enables operators to fine-tune the 400-500mm travel window during line changeovers, dialing in the exact end position via the rear screw rather than adding external shims.
Product Size Adjustments
Perfect for packaging lines that handle varying box sizes, allowing the 3927N thrust to push or index items to a precisely adjusted, repeatable stop point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100S the Right Cylinder?
Choose this 100mm bore when an application requires substantial thrust, such as the 3927N push or 3681N pull force available at just 0.5 MPa. If your setup demands less force, stepping down to an 80mm bore yields 2513N push force, whereas moving up to a 125mm bore provides 6136N. The adjustable stroke is ideal for variable end-stops and machine setups that require on-the-fly repositioning rather than a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100mm bore, 500mm stroke, 100mm adjustment range, PT tapered port threads, and the -S magnet. Because this model features a 500mm stroke, the 25mm rod and M20x1.5 thread carry significant side loads; for long unsupported strokes, always use an external guide to prevent rod binding. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ100X500-100S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster acts as an external stop that shortens the effective travel. For this 500mm nominal stroke cylinder, the -100 code means you can trim the stroke back by up to 100mm, creating a usable 400-500mm travel window to fine-tune the end position during commissioning.
