The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X150-30TC 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. Ø63mm bore, 150mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X150-30TC is a double-acting, single-rod pneumatic cylinder with a 63 mm bore and a nominal 150 mm stroke, offering a field-adjustable range of 30 mm via a rear-cap screw. This allows the stroke end position to be finely tuned without removing the cylinder, delivering 1559 N of push force at 0.5 MPa. The TC centre trunnion mount (supplied with TCM1 bracket) enables pivoting motion, making it ideal for swinging or articulating machine elements.
With a 20 mm piston rod and PT1/4 ports, this tie-rod cylinder provides reliable cushioning over a 28 mm length and operates at speeds of 30-800 mm/s. The adjustable stroke feature is perfect for commissioning trials, format changeovers, or taking up mechanical wear, ensuring consistent end-of-travel positioning in dynamic applications.

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 | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 30 mm rear adjuster lets technicians dial in the exact stroke end on a new machine during initial setup without swapping cylinders or machining external hard stops, saving hours of mechanical work.
On a packaging line, quickly adjust the push stroke for a different box size. The centre trunnion mount allows the cylinder to swing into position, and the screw fine-tunes the 150 mm stroke to match the new product width.
In a clamping or pressing fixture, the adjustable stroke can be extended by up to 30 mm over time to compensate for pad wear or material compression, maintaining consistent clamping force without a full cylinder replacement.
Step up to the 80 mm bore SCJ80 series for a significant force increase to 2513 N push at 0.5 MPa, or down to the 50 mm bore SCJ50 for 982 N if a more compact footprint is needed. The SCJ63X150-30TC is the correct replacement for an existing AirTAC SCJ cylinder of the same bore, 150 mm nominal stroke, 30 mm adjust range, PT port thread, and TC centre trunnion mounting (F-SC63TC). For a fixed end position, a standard SC63X150 cylinder is a simpler alternative. At this 150 mm stroke, side-loading is not typically a primary concern, but ensure the rod is aligned with the load path to prevent premature seal wear.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. The push force is higher due to the single-rod design. At the maximum 0.9 MPa operating pressure, push force increases to 2805 N.
Yes, if you need the ability to fine-tune the stroke end. The SCJ63X150-30TC has the same 63 mm bore and 150 mm nominal stroke as an SC63X150, but adds a 30 mm adjustable range. Ensure your mounting matches the TC centre trunnion style (F-SC63TC) and port thread is PT.
