About the Airtac SC50 Standard Cylinder SC50X1150TC
The SC50X1150TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), built around a 50 mm bore and a long 1150 mm stroke. Its 20 mm diameter piston rod and 21 mm adjustable air cushion work together to manage end-of-stroke deceleration effectively across this extended travel.
This model comes factory-configured with a centre trunnion (TC) mount, including the TCM1 bracket, allowing the cylinder to pivot freely as it strokes—ideal for swinging or articulating loads. The body length A is 150 mm, giving a total extended length of approximately 1300 mm, and it uses standard PT1/4 ports with M16x1.5 rod threads.

Where the Airtac SC50 Standard Cylinder SC50X1150TC Is Used
Long-Reach Part Transfer
The 1150 mm stroke and pivoting trunnion mount suit long linear transfer arms on packaging lines, moving parts between distant conveyor stations with controlled acceleration.
Articulating Clamp Fixtures
Pivots smoothly on the TC mount to actuate large welding or assembly jigs, providing 982 N of clamping force at standard shop air pressure.
Grain Chute Diverter
Operates a long-throw diverter gate in agricultural handling, where the trunnion mount absorbs the arc of motion and the 50 mm bore provides ample force.
Is the Airtac SC50 Standard Cylinder SC50X1150TC the Right Cylinder?
Choose the SC50X1150TC when your application needs a 50 mm bore's force profile with a pivoting mount. If you require higher force, the SC63 delivers 1559 N push at 0.5 MPa; for a more compact solution, the SC40 provides 628 N. At 1150 mm, this stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
For a stroke this long, side loads and rod bending are critical concerns. Never subject the rod to direct lateral force; use an external linear guide or rod support to absorb bending moments, or consider a guided cylinder assembly. For direct replacement, match the 50 mm bore, 1150 mm stroke, PT1/4 ports, centre trunnion (TC) mount, and the 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 SC50X1150TC FAQ
At 0.5 MPa, it produces 982 N extending and 825 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force rises to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
A stroke exceeding 300 mm increases the risk of rod buckling and bearing wear under side load. Always guide the load externally with a linear rail or rod, and ensure the load is aligned axially with the piston rod. The centre trunnion mount helps by allowing the cylinder body to self-align during the stroke.
