About the Airtac SC50 Standard Cylinder SC50X157STC
The SC50X157STC is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. With a 50 mm bore and a 157 mm stroke, this model features a 20 mm diameter piston rod and an M16x1.5 rod thread, making it a robust mid-range actuator for industrial automation tasks.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC50TC) for pivoting applications. The adjustable pneumatic cushion, with a 21 mm cushion length, decelerates the piston smoothly at end-of-stroke, while the standard PT1/4 port thread ensures straightforward pneumatic connections.

Where the Airtac SC50 Standard Cylinder SC50X157STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it ideal for actuating diverter gates on conveyor lines where the 157 mm stroke redirects packages between lanes.
Clamping & Fixturing
With 982 N of clamping force at 0.5 MPa and sensor confirmation via the built-in magnet, this cylinder reliably secures parts in CNC welding and assembly fixtures.
Pivoting Linkage Actuation
The TC trunnion mount absorbs side loads in pivoting linkages, using the 157 mm stroke to operate levers, chutes, or hopper doors in material handling systems.
Is the Airtac SC50 Standard Cylinder SC50X157STC the Right Cylinder?
Select the SC50 when your application requires a force class around 982 N at 0.5 MPa. If you need more force, stepping up to the SC63 bore provides 1559 N at the same pressure; for a lighter, more compact solution, the SC40 bore delivers 628 N. The 157 mm stroke is well within the 1200 mm maximum standard stroke for this bore, ensuring standard lead times.
For replacement, match five key points: 50 mm bore, 157 mm stroke, PT1/4 port thread, the TC centre trunnion mount with TCM1 bracket, and the -S magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC50X157STC FAQ
At the standard operating pressure of 0.5 MPa, this cylinder provides 982 N of push force and 825 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. For a drop-in replacement, you must match an AirTAC SC50 with the same stroke, PT port thread, TC trunnion mount, and -S magnet option.
