About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100
The AirTAC SAIJ100X500-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. It provides a usable travel window of 400-500 mm, letting you trim the nominal 500 mm stroke by up to 100 mm without swapping the cylinder or adding external stops. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This model features a 25 mm carbon steel piston rod and a G1/2 PT port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a travel stop to set deceleration endpoints and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100 Is Used
Product Size Changeover
Dial in the 400-500 mm travel window on the fly when switching a production line to a different pallet or package size, eliminating the need to physically swap out long-stroke cylinders.
Machine Setup Tuning
Use the 100 mm rear adjustment range to fine-tune the exact retraction end-stop during initial commissioning, ensuring precise machinery alignment without external shims.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or fixtures, relying on the adjustable stop to dial in the precise resting position for each cycle.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-100 the Right Cylinder?
Choose this 100 mm bore when you need higher thrust than the 80 mm option (2513 N at 0.5 MPa) but want to avoid the larger footprint of a 125 mm cylinder. The adjustable stroke is ideal for machine setups requiring variable end-stops or frequent product-size changeovers, whereas a fixed-stroke SAI cylinder is better for repetitive single-position tasks. For load-holding without continuous air pressure, consider an external rod lock or pilot-operated check valve, as the SAIJ adjuster is not a brake.
Because this cylinder has a 500 mm stroke, the long unsupported piston rod is susceptible to side-loading; an external guide is recommended to prevent premature wear. To match this ISO 15552 replacement exactly, verify the 100 mm bore, 500 mm stroke, 100 mm adjustment range, G1/2 port, and the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ100X500-100 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 100 mm. This creates a 400-500 mm usable travel window, allowing you to set the exact retract end-position at commissioning without changing the cylinder's physical mounting.
At a 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
