The AirTAC Airtac SC Standard Cylinders SC63X150S is a genuine double-acting standard air cylinder with a Ø63mm bore and 150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC63X150S is a double-acting tie-rod cylinder with a 63 mm bore and 150 mm stroke, producing roughly 1559 N on the push stroke at 0.5 MPa and 2182 N at 0.7 MPa. The -S suffix means a magnet is built into the piston, so CMSG, DMSG or EMSG sensors can clamp directly onto the barrel for end-of-stroke or mid-position detection without any external trigger.
With a 20 mm rod, 28 mm adjustable cushions and a body length A of 153 mm, the fully extended length is approximately 303 mm. Ports are PT1/4 and the TPU seal set covers -20 to +70 C, making this a dependable mid-force actuator for compact machine frames.

Around 1559 N at 0.5 MPa is well suited to clamping jigs and fixtures, and the built-in magnet lets a CMSG sensor confirm the clamp is fully made before the cycle starts.
The 150 mm stroke suits diverting or pushing cartons on packaging lines, with the magnet signal giving reliable retract confirmation to the PLC.
With 2182 N available at 0.7 MPa, this cylinder handles light pressing, staking and insertion tasks where a 28 mm adjustable cushion softens the approach into the work.
At 150 mm stroke this sits in the sweet spot for short-to-medium indexing moves. If your load needs more than about 1559 N at 0.5 MPa, step up to the 80 mm bore (2513 N at 0.5 MPa); if 982 N from a 50 mm bore is enough, you can shrink the envelope and air consumption. For strokes with any side load or long unsupported rods, pair the cylinder with an external guide or a guided cylinder to protect the rod bearing.
Replacing an existing unit? Match all five points: 63 mm bore, 150 mm stroke, PT1/4 port thread (PT here, or G if ordered with the G suffix), the same mounting accessory, and the magnet option (-S). This SC63X150S is magnet-equipped with a basic mount and TPU seals.
Quick checklist
At 0.5 MPa the 63 mm bore delivers about 1559 N pushing and 1402 N pulling. At 0.7 MPa push force rises to 2182 N, and at the 0.9 MPa maximum operating pressure it reaches 2805 N. Theoretical maximum force at 1.0 MPa is about 318 kgf.
The S suffix means a magnet is built into the piston, so CMSG, DMSG or EMSG reed or solid-state sensors clamp onto the barrel for position detection. Note that like any double-acting cylinder, the SC will not hold a load if air pressure is lost - use a mechanical lock or pilot-operated check valve if load holding is required.
