The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X50-10S 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, 50mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The AirTAC SCJ80X50-10S is a double-acting, single-rod pneumatic cylinder that delivers a robust 2513 N of push force at 0.5 MPa, making it suitable for medium-duty clamping and positioning tasks. Its key feature is the rear-cap adjusting screw, which provides a 10 mm field-adjustable stroke range, allowing operators to fine-tune the end position without swapping the cylinder.
This model is equipped with a built-in magnet (-S suffix), enabling direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors along the tie-rod barrel for precise end-of-stroke detection. The 25 mm diameter rod and PT3/8 port ensure a balanced combination of strength and flow capacity, while the 28 mm air cushion decelerates the piston quietly at the end of its travel.

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.
The 10 mm adjustable stroke is ideal for dialing in precise stop positions during machine commissioning, eliminating the need for iterative shimming or hard-stop adjustments on new equipment.
In high-cycle pick-and-place systems, the adjusting screw can be used to compensate for gripper pad wear over time, maintaining consistent contact pressure without reprogramming the controller.
Quickly adapt the cylinder's end-of-stroke position for different product sizes on a packaging line. The built-in magnet allows sensors to be repositioned to match the new stroke end for reliable cycle feedback.
Choose the SCJ80X50-10S when you need a compact, tie-rod cylinder with a 50 mm nominal stroke and the ability to dial in the exact stop point within a 10 mm window. If your force requirements increase, stepping up to the 100 mm bore provides 3927 N of push force at the same 0.5 MPa pressure. For applications where the stroke length is fixed and will never need field adjustment, the standard SC80X50 fixed-stroke cylinder is a simpler, more cost-effective alternative.
As a direct replacement, match this unit with another AirTAC SCJ adjustable-stroke cylinder of 80 mm bore, 50 mm nominal stroke, and a 10 mm adjustment range, ensuring the port thread is PT and the magnet option (-S) is present. The basic mounting configuration allows for direct body mounting or the addition of SCJ-compatible accessories like the FA front flange or LB foot mount.
Adjustable-stroke checklist
Being a single-rod cylinder, the push and pull forces differ. At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 5026 N.
The rear cap has an adjusting screw that acts as an internal, variable end-stop for the piston. By turning the screw, you can shorten the stroke end by up to 10 mm from its nominal 50 mm maximum. This adjusts the physical stopping point, not the air pressure or speed, and does not hold the load when air pressure is removed.
