About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-50
The AirTAC SAIJ100X175-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 125 to 175 mm, enabling precise end-position tuning at commissioning without swapping hardware. Operating at 0.5 MPa, it delivers 3927 N of push force, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered ports. The extruded aluminum barrel integrates sensor grooves on both sides for CMSE reed or DMSE electronic switches. It utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and relies on adjustable air cushions at both ends for deceleration, which do not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-50 Is Used
Machine Setup Changeover
Dial in the exact 125-175 mm travel window during product size changes on a machining line without swapping out the entire cylinder assembly.
Variable End-Stop Tuning
Fine-tune the retract end position during commissioning to perfect part ejection or clamping depth, avoiding the need for external stopper blocks.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa for moving substantial jigs or fixtures, using the built-in rear adjuster to set the precise resting point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-50 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust—up to 3927 N at 0.5 MPa or 7068 N at 0.9 MPa. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The 50 mm adjustment range is ideal for product changeovers on automated lines, allowing you to dial in the exact 125-175 mm travel without adding external mechanical stops.
For ISO 15552 interchangeability, match the 100 mm bore, 175 mm stroke, PT G1/2 port, and SUS304 rod material. Since the stroke is under 300 mm, side-load stress is manageable, but always guide the load properly. Note that the rear adjuster acts only as a travel stop; for load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ100BX175-50 FAQ
At a standard 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 175 mm down to as little as 125 mm. This creates a 50 mm tuning window for setting exact end positions without altering the cylinder mount.
