The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X150-75 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 75 mm range without swapping the cylinder. Ø80mm bore, 150mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X150-75 is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end tuning directly in your hands. With a 75 mm field-adjustable range on the rear cap, you can dial in the exact end position for a 150 mm nominal stroke without swapping the cylinder or adding external hard stops. It delivers 2513 N of push force at 0.5 MPa, making it a robust choice for mid-range automation tasks.
This 80 mm bore tie-rod cylinder uses a 25 mm diameter piston rod and PT3/8 ports. The integrated air cushion provides a 28 mm deceleration zone, and the body length (A dimension) is 239 mm. The rear screw shortens the stroke end only; it does not alter the cylinder's force output or speed, ensuring consistent performance as you fine-tune your machine's stopping point.

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.
Quickly fine-tune the actuator's end-stop during initial machine build and debug. The 75 mm screw adjustment lets technicians set the precise stroke needed without iterative cylinder swaps.
Adjust the push-off or stop position for different product sizes on a conveyor line. Operators can modify the stroke end in seconds to handle a new box or pallet dimension.
Take up mechanical slack in a clamping or pressing fixture over time. The adjustable stroke end can be extended to compensate for worn tooling or seals, maintaining consistent process force application.
Step up to a 100 mm bore SCJ for 3927 N of push force at 0.5 MPa if this 80 mm unit is undersized, or down to a 63 mm bore for 1559 N when space is tighter. Choose this SCJ over a fixed-stroke SC when your process requires frequent mechanical end-point adjustments, such as during commissioning or format changeovers. A direct replacement must match the 80 mm bore, 150 mm nominal stroke, 75 mm adjust range, PT3/8 port thread, and basic mounting. For this 150 mm stroke, side-loading is typically minimal, but always ensure the load is guided if any radial force is present to prevent premature rod bearing wear.
Adjustable-stroke checklist
At 0.5 MPa, the cylinder provides 2513 N of push force and 2268 N of pull force. The push force is higher because pressure acts on the full bore area, while pull force is reduced by the 25 mm rod cross-section.
Yes, if you need the 75 mm stroke-end adjustability. The SCJ80X150-75 has a slightly longer body (239 mm A-length) to house the adjusting screw. Ensure your mounting and port connections (PT3/8) are compatible, and note that the SCJ's rear cap profile is different.
