Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X170-20S
The AirTAC Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X170-20S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 170mm stroke, 1/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X170-20S
The AirTAC SAUJ32X170-20S is a double-acting single-rod profile cylinder with an on-site extend stroke adjustment. An external stop screw lets you shorten the 170 mm nominal travel by up to 20 mm, yielding a usable 150 to 170 mm window. It features a hard-anodized extruded aluminum barrel, making it shorter than an ISO 15552 cylinder of the same bore. The 1/8" port and M10x1.25 rod end keep the 32 mm bore compact.
Force output is 402 N push and 345 N pull at 0.5 MPa, scaling to 724 N push at 0.9 MPa. A practical computed insight: your safe working load is roughly 241 N (about 60 percent of the 0.5 MPa push force), translating to a 20 kg vertical lift with a 2:1 safety margin. The -S suffix means a built-in piston magnet is included for CMSG, DMSG, or EMSG position switches.

Where the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X170-20S Is Used
Gripper Jaw Timing
Dialing in the exact extend position for a robotic gripper that picks delicate parts, using the stop screw to tune the final 20 mm without reprogramming motion controllers.
Transfer Pusher Alignment
Adjusting a diverter pusher on a packaging line to match varying product widths, shortening the stroke on-site to prevent crushing items at the end of travel.
Clamping Force Setup
Setting a precise clamping endpoint for small component machining, where the external stop provides a hard mechanical position independent of pneumatic pressure fluctuations.
Is the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X170-20S the Right Cylinder?
Size this 32 mm bore against its neighbors: a 40 mm bore gives 628 N push at 0.5 MPa, while smaller compact units offer less thrust. Choose the SAUJ over a fixed SAU when your machine assembly needs final end-position tuning without buying a new cylinder. The -20 mm adjust window is ideal for minor mechanical alignment. Basic, FA, and LB mounts are available, sharing compatibility with the AirTAC SC series. The -S magnet allows electronic or reed sensing. For this 170 mm stroke, ensure external guide rails to prevent side-load wear.

- ✓ 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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X170-20S FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. Push force scales to 563 N at 0.7 MPa, 724 N at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The nominal 170 mm extend stroke can be shortened by up to 20 mm via the external stop screw, giving a usable range of 150 to 170 mm. It uses a 1/8" port.
No. The stop screw only sets the extend end position; it is not a load lock. A plain cylinder drifts on air loss, and the adjustable air cushion only decelerates the piston near the end of travel. To hold a load securely, you must add an external rod lock or a pilot-operated check valve.
