The AirTAC Airtac SCJ50 Standard Cylinder SCJ50X130-30STC 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. Ø50mm bore, 130mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ50X130-30STC is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw, giving you a 30 mm field-adjustable stroke-end range on a 130 mm nominal stroke. It delivers 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a strong mid-bore actuator for tasks needing fine end-position tuning.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (-TC) with the TCM1 bracket for pivoting applications. The 20 mm rod, PT1/4 ports, and 21 mm air cushion are standard for the 50 mm bore, with a body length A of 194 mm.

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.
Quickly adjust the stroke end by up to 30 mm when switching between product sizes on a packaging or assembly line, without swapping the cylinder.
The TC trunnion mount allows the cylinder body to pivot, while the adjustable stroke fine-tunes the clamping point for different workpiece thicknesses.
Set the precise open position of a material-handling gate, with the magnet providing sensor feedback to confirm the adjusted end-of-stroke.
Choose the SCJ50X130-30STC when your application requires a 50 mm bore force class with a 130 mm stroke that can be fine-tuned by up to 30 mm during commissioning or changeovers. The centre trunnion mount is ideal for loads that need to pivot, and the built-in magnet simplifies sensor integration for end-of-stroke detection. If a fixed stroke is sufficient, the standard SC50X130 offers the same force without the adjusting screw.
For replacement, match to another SCJ50 with a 130 mm nominal stroke, 30 mm adjust range, PT ports, TC mounting, and magnet. If you need more force, stepping up to a 63 mm bore provides 1559 N of push at 0.5 MPa. The 130 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
Adjustable-stroke checklist
At 0.5 MPa, it provides 982 N of push force and 825 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
Yes, the SCJ50X130-30STC is a direct replacement for an SC50X130 when you need field-adjustable stroke. Ensure your mounting matches the TC trunnion style, and the magnet option is compatible with your existing sensors.
