About the Airtac SC50 Standard Cylinder SC50X508S
The AirTAC SC50X508 is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa max operating pressure). Its 20 mm diameter piston rod and 508 mm stroke suit mid-range linear actuation tasks requiring extended reach.
This model is a non-standard stroke length, exceeding the standard 1200 mm maximum for bore 50, and is built to order. The tie-rod construction keeps the body length compact at 150 mm (A dimension), with an adjustable air cushion of 21 mm to decelerate the piston smoothly at end of travel.

Where the Airtac SC50 Standard Cylinder SC50X508S Is Used
Long-Reach Part Transfer
The 508 mm stroke moves components between distant conveyor stations or process steps, with 982 N push force handling moderate payloads.
Extended Clamping Fixtures
Applies consistent clamping pressure across a wide opening in woodworking or assembly jigs, using the adjustable cushion to reduce impact at full extension.
Diverting Gates and Flaps
Operates material diverters in chutes or hoppers where a long linear throw is needed to redirect bulk goods or packages.
Is the Airtac SC50 Standard Cylinder SC50X508S the Right Cylinder?
Select the SC50X508 when your application needs approximately 982 N of force at standard plant air pressure. If you require more force, the SC63 bore offers 1559 N push at 0.5 MPa; for a lighter, more compact solution, the SC40 provides 628 N. Because the stroke exceeds 300 mm, evaluate side-load conditions carefully—long, unsupported 20 mm rods can bend under lateral force; consider an external linear guide or a guided cylinder for off-axis loads.
To replace an existing cylinder, match five points exactly: 50 mm bore, 508 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X508S FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X508 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve centers, the piston can drift. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
