The AirTAC Airtac SCJ50 Standard Cylinder SCJ50X150-10 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. Ø50mm bore, 150mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ50X150-10 is a 50 mm bore double-acting single-rod cylinder with a field-adjustable stroke end, letting you fine-tune the stop position by up to 10 mm without swapping the unit. At 0.5 MPa it delivers 982 N push and 825 N pull, and its 20 mm rod with PT1/4 ports handles a wide range of pneumatic positioning tasks.
The rear adjusting screw shortens the nominal 150 mm stroke from the end, which is ideal for commissioning trials or taking up small mechanical tolerances. The cylinder body length A(SCJ) is 194 mm, and the standard air cushion is 21 mm long to decelerate the piston smoothly.

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 | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 dial in the exact stroke end during setup, compensating for fixture tolerances without re-machining hard stops.
On a packaging line, the adjustable stroke compensates for gradual wear on pusher pads, maintaining consistent product placement over thousands of cycles.
When clamping workpieces of slightly different widths, the screw adjusts the jaw closing point by up to 10 mm, preventing over-travel and part damage.
Choose the SCJ50X150-10 when you need a mid-range stroke with a small 10 mm end-adjustment window for fine-tuning. If your load requires more force, step up to the 63 mm bore (1559 N push at 0.5 MPa); for a lighter, more compact setup the 40 mm bore offers 628 N. This model is a direct replacement for another AirTAC SCJ50X150-10 with PT threads and basic mounting.
For strokes of 150 mm, rod deflection is generally not a concern under axial loads, but if the application introduces side forces, add an external guide rail or consider a guided cylinder to protect the rod bearing and seal.
Adjustable-stroke checklist
At 0.5 MPa, push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The pull force is lower because the 20 mm rod reduces the effective piston area on the return stroke.
Yes, if you need the 10 mm stroke-end adjustment. The SCJ50X150-10 shares the same bore, nominal stroke, and mounting interfaces as the SC50X150, but the body is slightly longer to house the adjusting screw. Ensure your machine has clearance for the extra length.
