About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-100
The AirTAC SAIJ32X165-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 165 mm travel back by up to 100 mm. This creates a highly flexible 65-165 mm usable window, enabling precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers a solid 402 N push force at 0.5 MPa, making it well-suited for compact actuation tasks.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 32 mm bore unit integrates variable air cushions at both ends to manage deceleration. The extruded aluminum barrel includes sensor grooves on both sides for straightforward positioning feedback. It features PT tapered port threading and operates reliably at speeds between 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-100 Is Used
Machine Changeover
Dial in the exact retract distance from 65 to 165 mm during product size transitions without physically replacing the actuator.
End-Position Tuning
Fine-tune the final retract position at commissioning using the rear stopper to clear mechanical interference.
Compact Assembly
Leverage the 402 N push force and 32 mm profile footprint to drive lightweight clamping and positioning tasks in tight spaces.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-100 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when your machine setup requires variable end-stops or frequent product-size changeovers, as the rear screw allows rapid fine-tuning of the retract position. If your application demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa.
Because the 165 mm stroke is well below the 300 mm threshold, side-load risks are minimal, though an external guide is still recommended for heavy lateral loads. Remember that the rear adjuster acts strictly as a travel stop, not a lock; this cylinder will not hold a load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series. This SKU matches the ISO 15552 mounting interface, utilizing the SAIJ subset of mounts (Basic, FA, LB, TC, FTC, TCM1, TCM2) without any magnet specified.

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 SAIJ32BX165-100 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjusting screw lets you shorten the 165 mm nominal stroke by up to 100 mm, creating a usable travel window of 65 to 165 mm. This stopper only sets the end position and does not lock the load without live air.
