About the Airtac SC50 Standard Cylinder SC50X85TC
The AirTAC SC50X85TC is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa max operating pressure). With an 85 mm stroke and a 20 mm diameter piston rod, it suits medium-force clamping, pressing, and positioning tasks where a compact tie-rod body is preferred.
This model is factory-configured with the TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC50TC), allowing the cylinder to pivot during operation. The adjustable air cushion at each end decelerates the piston smoothly, and the PT1/4 ports provide reliable pneumatic connection. The body length A is 150 mm, giving a total extended length of approximately 235 mm.

Where the Airtac SC50 Standard Cylinder SC50X85TC Is Used
Part Diverter
The centre trunnion mount lets this cylinder pivot to divert packages or components on a conveyor line, using its 982 N force to reliably push items onto a secondary lane.
Welding Fixture Clamp
Apply consistent clamping pressure to metal parts in a welding jig. The 85 mm stroke provides clearance for loading, and the tie-rod design handles repetitive industrial cycles.
Pivoting Linkage Actuator
Ideal for driving a pivoting arm or linkage in packaging machinery. The trunnion mount absorbs the arc motion, preventing side load on the piston rod and extending seal life.
Is the Airtac SC50 Standard Cylinder SC50X85TC the Right Cylinder?
Select the SC50 bore when your application needs around 982 N of force at standard plant pressure. If you require more force, step up to the SC63 (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 delivers 628 N. This 85 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
For replacement, match these five points: 50 mm bore, 85 mm stroke, PT port thread, TC centre trunnion mounting with TCM1 bracket, and no magnet. The SC series 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 SC50X85TC FAQ
At 0.7 MPa operating pressure, the SC50 bore generates 1374 N of push force on extension and 825 N of pull force on retraction. The maximum push force at 0.9 MPa is 1767 N.
Yes, the TC suffix indicates it is supplied with a centre trunnion mount and TCM1 bracket (F-SC50TC). This allows the cylinder body to pivot, which is essential for applications where the rod end follows an arc. Ensure the pin axis is perpendicular to the rod axis and the load is guided.
