About the Airtac SC50 Standard Cylinder SC50X525
The SC50X525 is a double-acting pneumatic cylinder with a 50 mm bore and a 525 mm stroke, which exceeds the standard maximum of 1200 mm for this bore, making it a non-standard, made-to-order length. It generates a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod with an M16x1.5 male thread.
This tie-rod cylinder features an adjustable pneumatic cushion at both ends with a 21 mm cushion length to decelerate the piston smoothly. The body length A is 150 mm, giving a total extended length of approximately 675 mm. It uses PT1/4 port threads and operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C with its standard TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X525 Is Used
Long-Reach Part Transfer
The 525 mm stroke pushes or pulls components across a wide conveyor gap, ideal for diverters or reject stations requiring extended linear reach.
Clamping & Fixturing
Delivers 982 N at 0.5 MPa to hold workpieces securely during machining or welding, with adjustable cushioning to prevent impact marks on delicate parts.
Bin Tipping & Dumping
Provides the long travel needed to tilt bins or hoppers for material discharge in agricultural or recycling handling systems.
Is the Airtac SC50 Standard Cylinder SC50X525 the Right Cylinder?
For applications needing slightly less force, the 40 mm bore SC40 series provides 628 N at 0.5 MPa. If higher force is required, stepping up to the 63 mm bore SC63 delivers 1559 N at the same pressure. Always match five key points when replacing: bore, stroke, port thread (PT), mounting accessory, and the presence of a magnet.
With a 525 mm stroke, the 20 mm rod is extended significantly. Avoid side loading, which can bend the rod or damage the bearing. For long-stroke applications with any lateral force, use an external guide rail or a guided cylinder to absorb the bending moment and protect the rod and seals.
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 SC50X525 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 at 1.0 MPa is 200 kgf.
A 525 mm stroke on a 20 mm rod is susceptible to bending under side loads. Mount the cylinder so the load is purely axial. If any lateral force is present, install an external linear guide or switch to a guided cylinder unit to protect the rod bearing and seals.
