The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X600-100S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø80mm bore, 600mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X600-100S is a double-acting, single-rod pneumatic cylinder that gives you a full 100 mm of field-adjustable stroke-end range, letting you fine-tune the 600 mm nominal stroke without swapping the unit. Its 25 mm diameter rod and 28 mm air cushion deliver controlled deceleration, while the built-in magnet allows direct mounting of CMSG/DMSG sensors for reliable end-of-stroke detection.
At 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N on the pull stroke, stepping up to 4523 N at the maximum operating pressure of 0.9 MPa. The tie-rod construction and PT3/8 ports make it a robust, serviceable workhorse for applications where the final stroke length must be dialled in precisely during commissioning or changeover.

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 100 mm adjustment screw allows engineers to precisely set the stroke end during initial machine setup without cutting or changing hard stops, dramatically reducing commissioning time for a 600 mm stroke actuator.
Ideal for pushers or diverters on packaging conveyors where the push distance must change between product sizes. Operators can quickly adjust the stroke end to handle different box widths or tray formats.
In long-running clamping or pressing fixtures, the adjustable stroke can be periodically extended to compensate for pad or tooling wear, maintaining consistent clamping force without replacing the cylinder.
Choose the SCJ80 bore when your application needs force in the 2500-4500 N range. If you require more power, stepping up to the 100 mm bore delivers 3927 N of push at 0.5 MPa; for a lighter, more compact solution, the 63 mm bore provides 1559 N. This adjustable-stroke model is the right pick over a fixed-stroke SC when you anticipate needing to tweak the end position to accommodate tooling wear, different product sizes, or process variations.
For this 600 mm stroke length, be mindful of side-loading on the rod. If the load is not guided and perfectly axial, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending and premature seal wear. To replace this exact model, match the 80 mm bore, 600 mm nominal stroke, 100 mm adjustment range, PT3/8 ports, and the -S magnet option; the basic mounting style uses no additional bracket.
Adjustable-stroke checklist
The push force is 2513 N at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. The pull force is slightly lower due to the 25 mm rod area, producing 2268 N at 0.5 MPa. This is a single-rod cylinder, so push and pull forces are not equal.
You can replace an existing AirTAC SCJ80X600-100S directly. If you are upgrading from a fixed-stroke SC80, ensure the 600 mm nominal stroke and 100 mm adjustment range fit your machine's geometry, as the SCJ body is slightly longer to house the rear adjusting screw. The port size (PT3/8) and mounting style must also match.
