Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-20S
The AirTAC Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-20S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 60mm stroke, 1/4" 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 SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-20S
The AirTAC SAUJ50X60-20S is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 60 mm nominal travel by up to 20 mm, yielding a usable 40-60 mm working window without buying a new actuator. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This -S variant includes a piston magnet for CMSG, DMSG, or EMSG position sensing.
In the 50 mm bore class, this cylinder delivers a 982 N push and 825 N pull at 0.5 MPa, scaling to 1767 N at 0.9 MPa. The 1/4" port and M16x1.5 rod thread match standard SAU hardware. For sizing, the safe working load is roughly 589 N (about 60% of the 0.5 MPa push), translating to a 50 kg vertical lift capacity with a 2:1 safety margin. Viton H seals can extend the -20 to +70 C operating range up to 150 C.

Where the Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-20S Is Used
Clamp Position Truing
Dial in exact clamping depth on machining fixtures by trimming the extend stroke up to 20 mm to compensate for part tolerance variations.
Variable Length Sealing
Adjust the pressing position on a carton sealing head to ensure consistent flap contact across different box heights without changing tooling.
Transfer Stop Alignment
Fine-tune the stopper block height on a conveyor diverter by up to 20 mm to perfectly match upstream product profiles on-site.
Is the Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-20S the Right Cylinder?
If you need less force, the 40 mm bore offers a 628 N push at 0.5 MPa; stepping up to the 63 mm bore yields 1559 N. Choose this 50 mm model when your application needs around 589 N of safe working load. Pick the SAUJ over a fixed SAU when you need final end-position tuning on the machine; the 20 mm adjust window is ideal for resolving minor mechanical clashes without machining new hard stops. Basic, FA, and LB mounts are available, sharing compatibility with the AirTAC SC series. The -S magnet supports electronic or reed switches. Because the 60 mm stroke is short, side-load risks are minimal, but always guide the load externally for any stroke over 300 mm.

- ✓ Stroke and mounting space
- ✓ 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 SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-20S FAQ
This 50 mm bore cylinder provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and 1767 N at 0.9 MPa. The theoretical max is 200 kgf at 1.0 MPa. The 60 mm nominal extend stroke can be shortened by up to 20 mm via the external stop screw, giving a 40-60 mm working range. It uses a 1/4" port and adjustable 21 mm air cushions.
The external stop screw mechanically limits the piston's extend travel to set the exact end position. It is not a load lock; the cylinder relies on live air, and the cushion only decelerates the piston near the end of the stroke. If air is lost, the load will drift. For fail-safe holding, install an external rod lock or a pilot-operated check valve.
