The AirTAC Airtac SAIJ50 Adjustable Cylinder SAIJ50AX600-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 600mm stroke, G1/4 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 SAIJ50X600-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a 500-600 mm usable stroke window, enabling precise end-position tuning at commissioning without swapping out the entire actuator. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa.
Built with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, this model uses PT tapered ports sized G1/4. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear adjuster and variable air cushions decelerate the piston at travel ends, note that neither component acts as a mechanical lock to hold the load without continuous air pressure.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Ideal for cutting or positioning stations where the material length changes frequently, using the 100 mm rear adjuster to shift the 500-600 mm travel window on the fly.
Enables rapid format part adjustments during product line changeovers, letting operators fine-tune the end position at the machine without disassembling pneumatic hardware.
Provides the long 600 mm reach needed to push wide pallets off a conveyor, while retaining the ability to shorten the stroke by up to 100 mm if the lane width is modified.
Choose this 50 mm bore when an application requires moderate thrust, such as 982 N push at 0.5 MPa, which sits neatly below the 63 mm bore's 1559 N capacity. The 100 mm adjustment range is ideal for product-size changeovers on a line, allowing operators to dial in the exact end-stop without adding external shims. If your process demands load-holding during an air pressure loss, a standard SAIJ will not suffice; you should explore the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
Because this cylinder features a 600 mm stroke, the M16x1.5 rod will experience leverage forces under side loading. For accurate guidance over this long travel distance, an external guide rail or linear bearing should be integrated to prevent premature seal wear. When replacing an ISO 15552 cylinder, verify the 50 mm bore, 600 mm stroke, 100 mm adjuster, PT port threads, and the required mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N. The operational speed range is 30-800 mm/s.
The rear adjusting screw acts as a mechanical stopper that shortens the nominal 600 mm stroke by up to 100 mm, giving a usable travel window of 500-600 mm. It allows precise end-position tuning during setup but does not lock the load without live air pressure.
