About the Airtac SC50 Standard Cylinder SC50X45TC
The SC50X45TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), ideal for compact linear actuation tasks. Its 45 mm stroke suits short clamping, pressing, or ejecting operations where space is limited.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The integrated centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allows the cylinder to pivot during operation, accommodating swinging or articulating loads without rod binding.

Where the Airtac SC50 Standard Cylinder SC50X45TC Is Used
Clamping Fixtures
Short 45 mm stroke and 982 N force at 0.5 MPa make it perfect for pneumatic work-holding clamps on CNC or welding jigs, with the trunnion mount allowing the body to self-align.
Part Diverter Gates
Centre trunnion mounting enables the cylinder to pivot as it actuates a diverter flap on a conveyor line, sorting packages by weight or barcode.
Linkage Actuation
Ideal for driving pivoting linkages on packaging or assembly machines where the cylinder must swing through an arc, preventing side-load damage to the rod bearings.
Is the Airtac SC50 Standard Cylinder SC50X45TC the Right Cylinder?
For higher force in the same footprint, step up to the SC63 bore (1559 N at 0.5 MPa). If a lower force profile is acceptable, the SC40 provides 628 N at 0.5 MPa. The centre trunnion mount is ideal for applications where the cylinder body must pivot.
When replacing this cylinder, match five key points: 50 mm bore, 45 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting accessory, and the absence of a built-in magnet. The SC series is a tie-rod design 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 SC50X45TC FAQ
At the standard 0.5 MPa operating pressure, 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.
The TC suffix indicates the cylinder is supplied with a centre trunnion bracket (F-SC50TC + TCM1). This allows the cylinder body to pivot on its centreline. When replacing, ensure the new cylinder has the same 50 mm bore, 45 mm stroke, PT1/4 ports, and centre trunnion mounting to maintain the pivot point and stroke alignment.
