About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-50S
The AirTAC SAIJ32X150-50-S 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 50 mm. With a nominal 150 mm stroke, this specific SKU yields a usable travel window of 100-150 mm, letting you fine-tune the retract end-position at commissioning without swapping out the barrel or adding external stops. It delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa, making it well-suited for lighter-duty machine setup tasks.
This unit is built with a SUS304 stainless steel piston rod (option B) for superior corrosion resistance and includes a magnetic piston (-S) for position detection with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid connections use PT tapered threads. Remember that the rear adjuster acts only as a travel stop to decelerate the load—it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-50S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 100 to 150 mm during machine commissioning to accommodate varying material lengths without external stopper hardware.
Product Size Changeover
Quickly adjust the stroke on packaging lines when switching between different package formats, using the 50 mm rear adjuster to set new endpoints.
Light-Duty Positioning
Leverage the 402 N push force at 0.5 MPa and SUS304 rod for precise, corrosion-resistant component placement in small assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-50S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires variable end-stops or frequent product-size changeovers, stepping down from a 40 mm bore (which provides 628 N at 0.5 MPa) to save space and airflow. The SAIJ32X150-50-S is configured with a 100-150 mm travel window, a PT port, and a -S magnet. When replacing an ISO 15552 cylinder, match the 32 mm bore, 150 mm nominal stroke, 50 mm adjustment range, and SUS304 rod material. Because the stroke is 150 mm, side loads are moderate, but always ensure proper guiding for long unsupported travel.
If your machine requires the load to stay locked in place without continuous compressed air, this standard SAIJ cylinder will not suffice; the rear screw is a stop, not a clamp. For true load-holding, consider the AirTAC SAIL (air-released lock) or BSAI (clamp-lock) series instead. The available mounting set for this profile cylinder includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX150-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw allows you to shorten the nominal 150 mm stroke by up to 50 mm, creating an adjustable travel window of 100-150 mm. This stopper decelerates the travel end but does not lock the load without live air pressure.
