The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 105mm 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.
The AirTAC SAIJ100X105-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the effective travel back by up to 40 mm. This specific configuration yields a usable stroke window of 65 to 105 mm, enabling precise end-position tuning at commissioning without swapping out the barrel or adding external stops. Built with a SUS420J2 stainless steel rod (material code A), it provides enhanced resistance to corrosion compared to standard carbon steel.
Delivering 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa, this 100 mm bore actuator handles substantial loads. The rear adjuster acts purely as a mechanical stop to set the retraction end-point; it does not hold the load without live air pressure. For true load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Dial in the 65-105 mm travel window during product line changeovers to accommodate varying package sizes without physically replacing the cylinder.
Use the rear adjusting screw to fine-tune the retraction end position during commissioning, preventing hard mechanical crashes at the end of the stroke.
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or fixtures, relying on the adjustable stop to set the exact resting distance.
Choose this 100 mm bore when your application requires the 3927 N push force at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The adjustable stroke is selected when you need variable end-stops for machine setup or product-size changeovers, rather than relying on a fixed-stroke SAI cylinder. Because this model lacks a magnet, it cannot host internal sensors; use external reed or solid-state switches if position feedback is required.
This SKU features PT tapered port threads and a G1/2 air supply connection. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options. Since the nominal stroke is 105 mm, an external guide is not strictly required for side-load management, but always ensure the M20x1.5 rod thread is properly aligned to prevent binding.
Quick checklist
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the nominal 105 mm stroke by up to 40 mm. This creates a usable travel window of 65 to 105 mm, which is set mechanically and does not require live air to maintain the stop position.
At a 0.5 MPa operating pressure, the SAIJ100X105-40 provides 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.9 MPa, the push force reaches 7068 N.
