The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X150-10 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, 150mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X150-10 delivers a substantial 2513 N of push force at 0.5 MPa, making it a workhorse for medium-duty automation. Its defining feature is the rear-cap adjusting screw, which allows you to fine-tune the stroke end position by up to 10 mm without dismounting the cylinder, perfect for dialing in precise stopping points during commissioning.
This double-acting, single-rod cylinder uses a 25 mm diameter piston rod and PT3/8 ports. The tie-rod construction houses a 28 mm air cushion for smooth deceleration, and the body length (A dimension) is 239 mm. The pull force at the same pressure is 2268 N, reflecting the single-rod area differential.

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 retract stroke end by up to 10 mm to perfectly align a pusher bar with a new product size on a packaging line, eliminating the need for shims.
In a clamping fixture, the adjusting screw can be periodically advanced to take up mechanical wear on the clamp pads, maintaining consistent clamping force without reprogramming.
During machine prototyping, engineers can quickly test different stroke lengths to find the optimal actuator travel for a new mechanism before committing to a fixed-stroke design.
Choose this 80 mm bore when the 63 mm model's 1559 N push force at 0.5 MPa is insufficient for your load. If you need more power, stepping up to the 100 mm bore provides 3927 N of push force. The adjustable stroke makes this ideal for applications where the final stop position needs empirical tuning, unlike a fixed-stroke SC cylinder. For replacement, match the 80 mm bore, 150 mm nominal stroke, 10 mm adjustment range, and PT port thread. If your application involves a long, unsupported rod extension, consider adding an external guide rail to prevent side-load induced bending.
Adjustable-stroke checklist
At the standard 0.7 MPa operating pressure, the push force is 3518 N and the pull force is lower at 3175 N due to the 25 mm rod area. The maximum push force at 1.0 MPa is 4523 N.
Yes, if you need the stroke adjustment feature. The SCJ80X150-10 has the same bore, port size (PT3/8), and maximum stroke, but its body is slightly longer to house the adjusting screw. Ensure the extra length fits your machine and that you need the 10 mm adjustment range.
