About the Airtac SC50 Standard Cylinder SC50X435
The AirTAC SC50X435 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a 435 mm stroke, this model suits mid-range linear actuation tasks where a compact body length (A=150 mm) is required.
This cylinder uses PT1/4 ports and an M16x1.5 rod thread, with an adjustable air cushion (21 mm length) to decelerate the piston smoothly at stroke ends. The 435 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore, making it a standard-order item. Operating temperature range is -20 to +70 °C with the default TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X435 Is Used
Material Transfer Gates
Actuates diverter gates on conveyor lines, using the 982 N push force at 0.5 MPa to reliably direct packages or bulk materials.
Clamping & Fixturing
Provides consistent clamping pressure for woodworking or metal fabrication jigs, where the 435 mm stroke accommodates varied workpiece sizes.
Agricultural Machinery
Operates sorting chutes or bin tippers in agricultural processing, leveraging the durable tie-rod construction and adjustable cushioning.
Is the Airtac SC50 Standard Cylinder SC50X435 the Right Cylinder?
Choose the SC50X435 when your application needs around 982 N of force at standard plant air pressure. If you require more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. For a lighter, more compact solution, the 40 mm bore (SC40) offers 628 N.
At 435 mm of stroke, the 20 mm rod is robust for axial loads, but always avoid direct side loading. For applications with any lateral force, use an external linear guide or rod support to prevent bending stress on the rod bearing. When replacing an existing cylinder, match five points: 50 mm bore, 435 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and absence of a 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 SC50X435 FAQ
At 0.5 MPa (5 bar), the push force is 982 N and the pull force (rod side) is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. Replace only with another AirTAC SC50 tie-rod cylinder matching the same bore, stroke, and port thread.
