The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X160-50STC is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 50 mm range without swapping the cylinder. Ø80mm bore, 160mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X160-50STC is a double-acting, single-rod pneumatic cylinder that puts 2513 N of push force at 0.5 MPa into a compact, field-adjustable package. Its rear-cap screw provides a 50 mm adjustment range, letting you fine-tune the stroke end position without removing the cylinder—ideal for commissioning trials or format changeovers on packaging machinery.
This model comes factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC) pivot with the TCM1 bracket for smooth swinging loads. The 25 mm rod, PT3/8 ports, and 28 mm air cushion handle high-cycle duties, while the TPU seals deliver reliable operation from -20 to +70 °C.

Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The 50 mm rear screw adjustment allows engineers to dial in the exact stroke end position during machine commissioning without swapping cylinders or machining external hard stops.
Quickly adapt the cylinder's end position for different product sizes on packaging or sorting lines. The centre trunnion mount lets the body pivot, accommodating the changing geometry of diverters or gates.
The built-in magnet enables precise end-of-stroke sensing with CMSG/DMSG switches, providing reliable position feedback to the PLC for high-speed automated assembly sequences.
Step up to the 100 mm bore SCJ if your application demands more than the 2513 N push force this 80 mm unit provides at 0.5 MPa; the 100 mm bore delivers 3927 N. For purely linear, fixed-end-position tasks, a standard SC fixed-stroke cylinder is a simpler, lower-cost alternative. This SCJ80X160-50STC is a direct dimensional replacement for any AirTAC SCJ80 cylinder with a 160 mm nominal stroke, 50 mm adjust range, PT ports, TC mount, and magnet sensor option.
At a 160 mm stroke, rod deflection is generally not a concern for axial loads, but if you're pushing an offset or unguided mass, an external guide rail or switching to a guided cylinder will protect the rod and bearing from side-load wear.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. The maximum push force at the 0.9 MPa operating limit is 4523 N. Because it's a single-rod cylinder, the pull force is lower due to the area of the 25 mm rod.
Yes, this is a direct replacement for any AirTAC SCJ80 adjustable-stroke cylinder with a 160 mm nominal stroke, a 50 mm adjustment range, PT ports, a centre trunnion (TC) mount, and a magnetic piston. Verify your existing TCM1 bracket is compatible, or order a new F-SC80TC assembly.
