Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X165-20
The AirTAC Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X165-20 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 165mm 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 SAUJ32X165-20
The AirTAC SAUJ32X165-20 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 20 mm, giving a usable range of 145 to 165 mm. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same 32 mm bore. It features a 1/8" port, an M10x1.25 rod thread, and 21 mm adjustable air cushions.
In this 32 mm class, the cylinder delivers 402 N push and 345 N pull at 0.5 MPa, peaking at 724 N push at 0.9 MPa. A practical computed insight: the safe working load is roughly 241 N, which translates to a vertical lift capacity of about 20 kg with a 2:1 safety margin. This SKU lacks a magnet, so it cannot accept position sensors. For high-heat environments beyond the standard -20 to +70 C range, Viton H seals extend operation to 150 C.

Where the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X165-20 Is Used
Actuator Positioning
Ideal for clamping stations where the exact extend endpoint must be dialed in by up to 20 mm during machine commissioning to accommodate material thickness variations.
Small Part Ejection
Provides adjustable ejection force for lightweight plastic parts, using the 402 N push at 0.5 MPa to push rejects off a conveyor without damaging the product.
Diverting Gate Control
Suits short-stroke diverting gates where the actuation distance needs field adjustment to perfectly meet the passing package profile without reordering hardware.
Is the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X165-20 the Right Cylinder?
Size this 32 mm bore against its neighbors: the 40 mm bore offers 628 N push at 0.5 MPa if you need more power, while the 32 mm provides 402 N. Choose the SAUJ over a fixed SAU when your machine assembly requires on-site tuning of the extend endpoint within that 20 mm window. The basic, FA flange, and LB foot mounts are available, offering compatibility with the AirTAC SC series. Because this specific SKU has no -S magnet, it cannot support CMSG or DMSG sensors. Since the 165 mm stroke is under 300 mm, side-load guide concerns are minimal, but always ensure rigid mounting. The external stop sets the end position but is not a load lock; without live air, the piston drifts and the cushion only decelerates near the end. Use a pilot-operated check valve for load holding.

- ✓ Port/thread type (PT/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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X165-20 FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. Push increases to 563 N at 0.7 MPa and 724 N at 0.9 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The 165 mm nominal extend stroke can be shortened by up to 20 mm via an external stop screw, yielding a usable 145 to 165 mm range. It uses a 1/8" port.
The external stop screw mechanically limits the piston's extend travel, letting you set the exact end position on-site. This stop is not a load lock; if air pressure drops, the cushion only decelerates the piston near the end but cannot prevent drift. For secure load holding, you must install an external rod lock or a pilot-operated check valve.
