About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10
The AirTAC SAIJ100X350-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 340-350 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning without external stops. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads with a 25 mm carbon steel rod and M20x1.5 thread.
This model includes a PT tapered port (G1/2) and variable air cushions at both ends for controlled deceleration. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It supports a speed range of 30-800 mm/s and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omitting FB and CA options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10 Is Used
Machine Changeover
Dial in the 340-350 mm stroke window during product size changes to set new end positions rapidly without swapping cylinders.
End-Stop Tuning
Fine-tune the final retract position during commissioning using the rear adjuster to clear mechanical interference.
Heavy Load Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or fixtures, adjusting the stop to vary the push distance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-10 the Right Cylinder?
Choose this 100 mm bore when 50 mm (982 N) is too weak but 125 mm (6136 N) is excessive. The 10 mm adjustment window is ideal for precise end-position tuning at machine setup. Because the stroke is 350 mm, the long unsupported piston rod requires an external guide to prevent excessive side-load wear. The rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider the SAIL or BSAI series. To match this ISO 15552 replacement, specify bore 100, stroke 350, 10 mm adjustment, PT port, and no magnet.
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 SAIJ100X350-10 FAQ
A rear external screw stopper lets you shorten the nominal 350 mm stroke by up to 10 mm, creating a 340-350 mm adjustable travel window for fine-tuning end positions at commissioning.
At 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
