Airtac SCJ100 Standard Cylinder SCJ100X60-50
The AirTAC Airtac SCJ100 Standard Cylinder SCJ100X60-50 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 50 mm range without swapping the cylinder. Ø100mm bore, 60mm nominal stroke, PT1/2 ports and adjustable end cushioning.

About the Airtac SCJ100 Standard Cylinder SCJ100X60-50
The SCJ100X60-50 delivers a substantial 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa), making it a workhorse for heavy-duty clamping and pressing tasks. Its defining feature is the 50 mm rear-cap adjusting screw, which lets you fine-tune the stroke end position on the fly without disconnecting the cylinder—ideal for commissioning runs or taking up tooling wear.
This double-acting, single-rod cylinder uses a 25 mm diameter rod and PT1/2 ports, with an adjustable air cushion to decelerate the piston smoothly. The tie-rod body length (A dimension) is 245 mm, and the standard stroke ceiling for the 100 mm bore is 1500 mm, so this 60 mm nominal stroke is well within standard limits.
Airtac SCJ100 Standard Cylinder SCJ100X60-50 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X60-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 60 mm |
| Stroke adjustment | Up to 50 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 29 mm |
| Max stroke | Up to 1500 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.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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.

Where the Airtac SCJ100 Standard Cylinder SCJ100X60-50 Is Used
End-Stop Tuning on Presses
The 50 mm adjustment range allows operators to quickly compensate for material thickness variations in a stamping or forming press without changing the tooling.
Product Diverters
Fine-tune the pusher arm's extended position on a conveyor diverter to handle different package widths, ensuring reliable product routing.
Wear Take-Up in Clamping
As clamp pads wear down over thousands of cycles, the rear adjusting screw can be turned to restore the original clamping force and position, extending maintenance intervals.
Is the Airtac SCJ100 Standard Cylinder SCJ100X60-50 the Right Cylinder?
Step up to the 125 mm bore (6136 N push at 0.5 MPa) if your load exceeds the SCJ100's capacity, or down to the 80 mm bore (2513 N) to save space and air. Choose this SCJ over a fixed-stroke SC when you need to dial in the end position during setup or for different product batches. For a direct replacement, match the 100 mm bore, 60 mm nominal stroke, 50 mm adjust range, PT thread, and basic mounting. At this stroke length, rod bending is not a primary concern, but for off-axis loads, consider an external guide rail.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ100 Standard Cylinder SCJ100X60-50 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The maximum push force at the 0.9 MPa operating limit is 7068 N. Because it is a single-rod cylinder, the pull force is lower due to the rod area.
Yes, if you need field-adjustable stroke. The SCJ100X60-50 has the same bore, port (PT1/2), and rod (25 mm) as an SC100, but its body is slightly longer to house the adjusting screw. Ensure the 50 mm adjustment range and the extra length fit your machine.
