The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X350-10 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø80mm bore, 350mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X350-10 delivers up to 350 mm of nominal stroke with a 10 mm rear-end adjustment range, letting you dial in the exact stroke end position on the machine. At 0.5 MPa, this 80 mm bore single-rod cylinder produces 2513 N of push force and 2268 N on the pull stroke, driven through a 25 mm diameter piston rod and PT3/8 ports.
Its tie-rod body measures 239 mm in the retracted state, and the integral air cushion provides a 28 mm deceleration zone at each end. The rear adjusting screw shortens the stroke end by up to 10 mm, making it practical for commissioning tweaks or format changeovers without removing the cylinder from the line.

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 10 mm rear adjuster lets technicians tweak the retract end position during commissioning, compensating for small fixture or tooling variances without shimming or re-machining mounts.
On packaging or assembly lines, operators can quickly adjust the stroke end to accommodate different product sizes or pallet widths, reducing downtime between batch runs.
Over time, gripper pads or push plates may wear. The adjustable stroke screw provides a simple way to recover the lost travel and maintain consistent part contact.
Step up to the 100 mm bore SCJ if you need more push force—the SCJ100 delivers 3927 N at 0.5 MPa. If your application requires a fixed, non-adjustable stroke, the standard SC80 series is a simpler alternative. For guided loads or where side forces are present, consider pairing this cylinder with an external linear guide or a dedicated guided cylinder, as the 350 mm stroke on a 25 mm rod can be susceptible to bending under off-axis loads.
This model is a direct replacement for another AirTAC SCJ80X350-10 with PT ports and basic mounting. If your original unit included a magnet or mounting bracket, match those suffix options exactly when reordering.
Adjustable-stroke checklist
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 1.0 MPa, theoretical push force reaches 5026 N. The pull force is lower because the 25 mm rod reduces the effective piston area on the return stroke.
Only if you need the adjustable stroke feature. The SCJ80X350-10 has a longer body than a fixed-stroke SC80 due to the rear adjusting mechanism. Mounting dimensions differ, so verify the overall length and mounting hole pattern against your machine before ordering.
