About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-50S
The AirTAC SAIJ32X100-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. Equipped with a SUS304 stainless steel rod and PT tapered ports, it provides a usable travel window of 50 to 100 mm, allowing you to dial back the nominal stroke by up to 50 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks.
Because the adjuster acts as a mechanical stop on the retract end, you can fine-tune the end position without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. Remember that the rear screw and the variable air cushions only decelerate the travel end; they do not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-50S Is Used
Machine Changeover
Dial in the exact retract distance from 50 to 100 mm instantly when switching between product sizes on a packaging line, avoiding physical cylinder swaps.
End-Position Tuning
Fine-tune the final end-of-stroke position during commissioning to perfect a delicate pressing or alignment operation without external stopper blocks.
Sensor Calibration Rigs
Leverage the SUS304 rod and CMSE/DMSE sensor compatibility to test and verify travel limits across a 50-100 mm window in laboratory automation equipment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-50S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your machine setup requires variable end stops or frequent product-size changeovers, stepping up to the 40 mm bore (628 N push at 0.5 MPa) only if your thrust requirements increase. The SAIJ32X100-50-S is specified with a SUS304 rod, a PT port thread type, and a magnet for position sensing. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the adjuster. Since this unit features a 100 mm stroke, side-load risks are minimal, but long unsupported strokes still necessitate an external guide.

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 Adjustable Cylinder SAIJ32 SAIJ32BX100-50S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 100 mm nominal stroke down to as little as 50 mm, giving a 50-100 mm usable window. It sets the retract end position but does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ32X100-50-S provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
