The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X160-30 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø80mm bore, 160mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X160-30 is an 80 mm bore double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides up to 30 mm of field-adjustable stroke-end reduction. This allows fine-tuning of the piston stop position without removing the cylinder from the machine, making it ideal for commissioning, format changeovers, and wear compensation. At 0.5 MPa, it delivers 2513 N of push force and 2268 N on the pull stroke, with a 25 mm diameter piston rod and a 28 mm air cushion for smooth deceleration.
Built on a robust tie-rod construction with a PT3/8 port and an M20x1.5 rod thread, this cylinder has a body length of 239 mm and operates reliably between -20 and +70 °C with its standard TPU seals. The nominal 160 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring ready availability. The adjustable screw only sets the stroke end position; it does not alter the cylinder's force output or speed capabilities, which remain at 30-800 mm/s.

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.
Fine-tune the clamp stroke end to accommodate varying workpiece thicknesses or fixture wear without reprogramming the PLC, using the 30 mm adjustment range.
Adjust the stop position for different product sizes on a conveyor line. The 2513 N push force at 0.5 MPa provides a solid, repeatable stop for medium-weight packages.
Dial in the precise press depth during setup or after tooling changes. The rear screw allows quick stroke-end calibration without disassembling the actuator.
Select the SCJ80X160-30 when your application requires a 160 mm nominal stroke with the ability to shorten the end position by up to 30 mm on the fly. If you need more force, stepping up to the 100 mm bore SCJ series provides 3927 N of push force at the same 0.5 MPa pressure. For applications where the stroke length is fixed and will never need adjustment, the standard SC80X160 fixed-stroke cylinder is a more economical choice. This model is a direct replacement for an existing AirTAC SCJ80X160-30 with PT ports and basic mounting. If your load is guided and requires a pivoting motion, consider adding the TC centre trunnion mount.
Adjustable-stroke checklist
A rear-cap adjusting screw limits how far the piston can extend, shortening the effective stroke by up to 30 mm from the nominal 160 mm. You turn the screw to set the desired end position. It does not change the cylinder's 2513 N push force at 0.5 MPa or its speed.
Yes, this is a genuine AirTAC SCJ80X160-30 with PT3/8 ports and basic mounting. It is a direct dimensional and performance match for an AirTAC SCJ of the same bore, nominal stroke, and30 mm adjustment range. Verify your port thread and mounting style match.
