The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X160-100 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, 160mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X160-100 is an 80 mm bore, double-acting single-rod pneumatic cylinder that puts stroke-end fine-tuning directly in your hands. Its rear-cap adjusting screw provides a full 100 mm of adjustment range, letting you dial in the exact 160 mm nominal stroke on the machine without swapping parts. At 0.5 MPa it delivers 2513 N of push force and 2268 N on the pull stroke, backed by a 25 mm piston rod and PT3/8 ports.
Built on a proven tie-rod platform with a 239 mm base body length, this cylinder includes an adjustable air cushion to decelerate the piston smoothly. The operating range spans 0.15–1.0 MPa and -20 to +70 °C, with a maximum push force of 4523 N at 0.9 MPa. It accepts the SCJ mounting subset—basic, FA, LB, or TC centre trunnion—and an optional magnet for barrel-mounted sensors.

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.

| 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.

A packaging line running different box sizes uses the 100 mm adjustment range to quickly reset the pusher stroke end between batches, eliminating mechanical stop changes.
In a woodworking clamp, the screw compensates for workpiece thickness variation and jaw pad wear over thousands of cycles, maintaining consistent clamping pressure without reprogramming.
During machine commissioning, engineers fine-tune the actuator stroke end on the fly to optimise transfer timing, then lock the setting for production.
Choose the SCJ80 when your application needs the 2513 N push force available from an 80 mm bore at standard plant air. If your load is lighter and you can accept a smaller footprint, the 63 mm bore delivers 1559 N push; for heavier work, stepping up to the 100 mm bore provides 3927 N push at the same 0.5 MPa. The 100 mm adjustable range on this model is ideal for format changes or wear take-up where the stroke must be reduced by a substantial margin from the nominal 160 mm.
For replacement, match an AirTAC SCJ80 with a 160 mm nominal stroke, -100 adjust range, PT thread, and the same mounting accessory. If your process demands a fixed, non-adjustable stroke, the standard SC series is a simpler alternative. At 160 mm stroke, rod bending under side load is generally not a concern, but any off-axis force should still be managed with an external guide or by selecting a guided cylinder.
Adjustable-stroke checklist
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 1.0 MPa, theoretical push force reaches 5026 N (513 kgf). The pull force is lower because the 25 mm rod reduces the effective piston area on the return stroke.
Yes, provided the mounting, port thread (PT), and nominal 160 mm stroke match. The SCJ80X160-100 body is slightly longer than a fixed-stroke SC80 to accommodate the adjusting screw, so verify the available space. The adjustment screw sets the stroke end only and does not alter the bore or force output.
