The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X160-50TC 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. Ø80mm bore, 160mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X160-50TC is an 80 mm bore, double-acting, single-rod pneumatic cylinder with a nominal 160 mm stroke and a 50 mm rear-end adjustable range. It delivers 2513 N of push force at 0.5 MPa, making it suitable for medium-force clamping, pressing, and positioning tasks where the final stroke length needs fine-tuning on the machine.
A rear-cap adjusting screw lets you shorten the stroke end by up to 50 mm without changing the cylinder, ideal for commissioning trials or format changeovers. This model features a TC centre trunnion mount (supplied with the TCM1 bracket, order code F-SC80TC) for pivoting applications, a 25 mm piston rod, PT3/8 ports, and a 28 mm air cushion for smooth deceleration.

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.

Fine-tune the final position of a material stop or pusher on a conveyor line during commissioning, using the 50 mm adjustment range to achieve precise alignment without swapping cylinders.
Quickly adapt a packaging machine's stroke for different box sizes. The rear screw allows operators to adjust the 160 mm nominal stroke in-field, minimizing downtime between production runs.
In clamping fixtures, use the adjustable stroke to take up mechanical wear on tooling or workpieces over time, maintaining consistent clamping force without reprogramming the PLC.
Choose the SCJ80 bore when your application needs around 2513 N of push force at standard plant pressure. If you require more force, step up to the 100 mm bore which provides 3927 N push at 0.5 MPa; for a lighter, more compact solution, the 63 mm bore offers 1559 N. This adjustable-stroke model is the right pick when you need to dial in the stroke end position on-site, rather than ordering a fixed-stroke SC cylinder.
For a direct replacement, match an AirTAC SCJ adjustable-stroke cylinder with an 80 mm bore, 160 mm nominal stroke, a 50 mm adjust range, PT ports, and a TC centre trunnion mount. At 160 mm stroke, rod bending is not a primary concern, but for very high side loads, consider adding an external linear guide.
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. The theoretical force at 1.0 MPa is 513 kgf.
A screw in the rear cap acts as an internal stroke limiter. You can shorten the piston's full extension by up to 50 mm from the 160 mm nominal stroke. This adjusts only the stroke end position; it does not change the cylinder's force or speed.
