The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-30S 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, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The AirTAC SCJ63X160-30S is a double-acting, single-rod pneumatic cylinder that integrates a rear-cap adjusting screw, giving you 30 mm of field-adjustable stroke-end control without replacing the unit. With a 63 mm bore, it delivers 1559 N of push force at 0.5 MPa, making it a robust choice for mid-range automation tasks where the final stop position must be dialled in precisely during commissioning or changeover.
A built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for reliable end-of-stroke detection. The 20 mm piston rod and 28 mm air cushion work together to handle deceleration smoothly, while the standard PT1/4 ports and TPU seals suit general industrial environments from -20 to +70 °C.

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.
Fine-tune the final stop position of a 63 mm bore actuator during machine commissioning. The 30 mm adjustment screw lets technicians dial in the exact stroke end for part placement without changing hard stops or reprogramming.
Quickly adapt a packaging machine to a new box size. The adjustable stroke end accommodates different product widths on a conveyor diverter, reducing downtime between production runs.
In clamping or pressing fixtures, use the rear screw to take up mechanical wear on tooling or seals over time. This maintains consistent clamping force and position without swapping the cylinder.
Choose the SCJ63X160-30S when you need a 63 mm bore's force class (1559 N push at 0.5 MPa) with the ability to fine-tune the stroke end by up to 30 mm. If your force requirement is lower, stepping down to a 50 mm bore reduces push force to 982 N; for higher demands, the 80 mm bore jumps to 2513 N. The built-in magnet is essential if you plan to use solid-state or reed sensors for piston position feedback.
This model directly replaces any AirTAC SCJ63X160-30S with PT threads and a basic mount. For a fixed, non-adjustable stroke, consider the standard SC63X160; if you need a guided, rigid assembly to manage side loads, a guided cylinder is the better pick. The 160 mm stroke is well within the 1500 mm maximum for this bore, so no special rod support is required.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. The maximum push force at the 0.9 MPa operating limit is 2805 N. Because it is a single-rod cylinder, the push force is always greater than the pull force due to the rod area.
A rear-cap screw mechanically limits how far the piston can extend, shortening the nominal 160 mm stroke by up to 30 mm. It only sets the stroke end position; it is not a locking device. If air pressure is lost, the piston will not hold its position. For load holding, you must add an external rod lock or pilot-operated check valve.
