About the Airtac SC50 Standard Cylinder SC50X508
The AirTAC SC50X508 is a double-acting, single-rod 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 20 mm diameter piston rod, it features an M16x1.5 rod thread and PT1/4 ports, making it a compact yet powerful actuator for medium-force applications.
This model specifies a 508 mm stroke, which exceeds the standard maximum of 1200 mm for the 50 mm bore, making it a non-standard, made-to-order length. The cylinder body length A is 150 mm, and it includes a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing impact noise and vibration at the end of travel.

Where the Airtac SC50 Standard Cylinder SC50X508 Is Used
Material Transfer
Pushes or diverts boxes and totes on a conveyor line. The 508 mm stroke provides the extended reach needed to move items fully across a wide belt.
Clamping & Fixturing
Applies 1767 N of clamping force at 0.9 MPa to secure workpieces during machining or welding. The adjustable cushion prevents jarring on clamp contact.
Lift Gate Actuation
Operates a lift gate or hopper door on bulk handling equipment, using its long stroke for full-open travel and its 20 mm rod for push-pull durability.
Is the Airtac SC50 Standard Cylinder SC50X508 the Right Cylinder?
Select the SC50X508 when your application requires a push force around 982 N at 0.5 MPa. If you need higher force, consider stepping up to the SC63 bore, which provides 1559 N at the same pressure. For lower force requirements, the SC40 bore offers 628 N. The 508 mm stroke is a non-standard length, so verify lead times for this made-to-order configuration.
For this 508 mm stroke, be mindful of side loads. Long, unsupported piston rods are susceptible to bending under lateral forces. If your application involves any side loading, use an external linear guide or a guided cylinder to protect the rod bearings and ensure reliable service life. When replacing an existing cylinder, match all five critical points: 50 mm bore, 508 mm stroke, PT1/4 port thread, basic (no) mounting, and no magnet.
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 SC50X508 FAQ
The theoretical push force is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and 1767 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is 825 N at 0.5 MPa due to the area of the 20 mm piston rod.
No. The SC50X508 is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end; it does not lock or hold the load. For position holding without pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
