Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-40S
The AirTAC Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-40S 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 SAUJ50X60-40S
The AirTAC SAUJ50X60-40S is a double-acting, single-rod profile cylinder with a 50 mm bore and a 60 mm maximum extend stroke. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable working stroke of 20 to 60 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. This bore uses a 1/4" port, a 20 mm rod, and 21 mm adjustable air cushions.
Force output matches the standard SAU series: 982 N push and 825 N pull at 0.5 MPa, scaling to 1767 N at 0.9 MPa. For sizing, the safe working load is roughly 589 N (about 60 percent of the 0.5 MPa push figure), translating to a 50 kg vertical lift capacity with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position sensors. Choose this adjustable unit over a fixed SAU plus an external hard stop when you need to fine-tune the end position during machine commissioning.

Where the Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-40S Is Used
Pin Insertion Depth Tuning
Dial in the exact insertion depth on-site using the 40 mm stop screw window, adapting to material thickness variations without changing the cylinder.
Variable Carton Sealing
Adjust the extend stroke from 20 to 60 mm to accommodate different flap heights on a packaging line, ensuring precise sealing pressure.
Sensor Probe Positioning
Leverage the built-in magnet and CMSG switches to verify the end position of a testing probe while trimming the stroke for various part geometries.
Is the Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X60-40S the Right Cylinder?
Size this 50 mm bore against its neighbours: a 40 mm bore yields 628 N push at 0.5 MPa, while a 63 mm bore provides 1559 N. The 50 mm bore gives 982 N push at 0.5 MPa, making it ideal for medium loads. Select the SAUJ over a fixed-stroke SAU when your final extend position needs on-site adjustment rather than machining a separate external stop. The 40 mm adjust window lets you dial in the exact 20 to 60 mm stroke. Mounting options include Basic, FA flange, and LB foot, with compatibility matching the AirTAC SC series. The -S magnet allows CMSG/DMSG/EMSG sensors for end-position confirmation. Because the 60 mm stroke is short, side-load risks are minimal, but always guide the load for any stroke over 300 mm.

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 SAUJ50X60-40S FAQ
This 50 mm bore cylinder has a 1/4" port, a 20 mm rod, and 21 mm adjustable cushions. Force is 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 nominal 60 mm extend stroke can be shortened by up to 40 mm via the external stop screw, giving a 20 to 60 mm usable range.
The external stop screw mechanically sets the extend end position but does not lock the load. If air pressure drops, the piston drifts because the air cushion only decelerates motion near the end of the stroke. For secure load holding, install an external rod lock or a pilot-operated check valve.
