About the Airtac SC50 Standard Cylinder SC50X475
The AirTAC SC50X475 is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 475 mm stroke, this model is well-suited for medium-duty linear tasks requiring a substantial reach, such as material transfer or clamping across a wide span.
This cylinder features a 20 mm diameter piston rod and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. The body length A is 150 mm, bringing the total extended length to approximately 625 mm. It uses PT1/4 ports and an M16x1.5 rod thread, operating on filtered air within a standard temperature range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X475 Is Used
Material Transfer
Extends across a 475 mm stroke to push or divert medium-weight packages on conveyor lines, providing 982 N of force at standard shop air pressure.
Clamping & Fixturing
Applies consistent clamping pressure to hold workpieces in CNC fixtures or welding jigs, with an adjustable cushion to reduce vibration at the end of travel.
Bin Pusher Actuation
Ideal for long-reach pusher arms in automated storage systems, where the 20 mm rod and tie-rod construction offer reliable, repeatable motion.
Is the Airtac SC50 Standard Cylinder SC50X475 the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa, while the 40 mm bore offers 628 N if a smaller footprint is required. At a 475 mm stroke, the piston rod is significantly extended; ensure side loads are minimal or use an external guide rail to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, verify five key points: the 50 mm bore, the 475 mm stroke, the PT1/4 port thread, the basic mounting style (no accessory bracket), and the absence of a built-in magnet. This model is a direct replacement for another AirTAC SC50X475 tie-rod cylinder with matching specifications.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X475 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X475 is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. To safely hold a load without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
