About the Airtac SC50 Standard Cylinder SC50X150TC
The AirTAC SC50X150TC is a double-acting tie-rod cylinder with a 50 mm bore and 150 mm stroke, factory-equipped with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 982 N of push force and 825 N on the pull stroke, making it a capable mid-range actuator for moderate loads.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, while the TC mount and included TCM1 bracket allow the cylinder to swing through an arc without binding.

Where the Airtac SC50 Standard Cylinder SC50X150TC Is Used
Conveyor Diverters
The 150 mm stroke and pivoting TC mount suit medium-reach diverter gates on packaging conveyors, where the cylinder swings to push product onto a spur line.
Clamping & Fixturing
Delivers 982 N of holding force for pneumatic clamps and weld fixtures. The trunnion mount lets the cylinder self-align as the clamp arm rotates.
Hopper & Chute Actuation
Operates discharge gates on hoppers and chutes in agricultural processing. The tie-rod construction handles dusty environments when air supply is properly filtered to 40 µm.
Is the Airtac SC50 Standard Cylinder SC50X150TC the Right Cylinder?
Choose the SC50 when your load requires roughly 980 N at standard plant pressure; stepping up to a 63 mm bore delivers 1559 N at the same 0.5 MPa, while a 40 mm bore provides 628 N for lighter, faster cycles. The 150 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
For replacement, match five points: 50 mm bore, 150 mm stroke, PT1/4 ports, centre trunnion (TC) mounting with the F-SC50TC bracket, and no magnet. If your application involves a side load, consider an external guide or a guided cylinder, as the SC series is not designed to absorb lateral forces on the rod.
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 SC50X150TC 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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
The TC suffix means it is supplied with a centre trunnion and TCM1 bracket for pivoting. If you need a fixed foot mount instead, order the basic SC50X150 and add the LB foot bracket (F-SC50LB) separately, or specify the SC50X150LB model.
