The AirTAC Airtac SCJ50 Standard Cylinder SCJ50X160-50TC 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. Ø50mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ50X160-50 is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning directly on the machine. Its rear-cap adjusting screw provides a 50 mm adjustment range, letting you dial in the exact 160 mm nominal stroke endpoint without dismounting the cylinder or adding external hard stops.
With a 20 mm piston rod and PT1/4 ports, this 50 mm bore actuator delivers 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. The adjustable air cushion on both ends decelerates the piston smoothly, and the 21 mm cushion length helps manage end-of-stroke impact in fast-cycling applications.

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 | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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.
Field technicians can fine-tune the stroke end by up to 50 mm during initial machine setup, eliminating the need to stock multiple fixed-stroke cylinders for trial-and-error positioning.
On packaging or sorting lines, operators quickly adjust the cylinder stroke to accommodate different product sizes without mechanical rework, reducing downtime between batches.
In clamping or pressing fixtures, the adjustable screw takes up mechanical wear or material compression over time, maintaining consistent contact force without replacing the actuator.
Choose this 50 mm bore when your application needs the force headroom between the smaller 40 mm bore (628 N push at 0.5 MPa) and the larger 63 mm (1559 N). The 50 mm adjustable range is ideal for commissioning trials or format changeovers where the stroke must be tweaked repeatedly. If your stroke never changes, the fixed-stroke SC50X160 is a simpler, lower-cost alternative.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket under part code F-SC50TC, which lets the cylinder pivot and is perfect for swinging or articulating loads. For a direct replacement, match the 50 mm bore, 160 mm nominal stroke, 50 mm adjust range, PT port thread, and TC mounting style.
Adjustable-stroke checklist
At 0.5 MPa, this single-rod cylinder generates 982 N pushing and 825 N pulling. At the maximum operating pressure of 1.0 MPa, push force reaches 1964 N. The rear adjusting screw changes only the stroke end position, not the output force.
Yes, if you need field-adjustable stroke. The SCJ50X160-50 shares the same bore, port size, and mounting interfaces as the SC50 series. Ensure your machine can accommodate the slightly longer SCJ body length (A=194 mm) and that the 50 mm adjustment range covers your stroke variation needs.
