About the Airtac SCJ100 Standard Cylinder SCJ100X50-50TC
The SCJ100X50-50TC is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end tuning directly on the machine. Its rear-cap adjusting screw gives a 50 mm adjustable range, letting operators dial in the exact stop position for a 100 mm bore without swapping the cylinder. At 0.5 MPa, it delivers 3927 N of push force and 3681 N on the pull stroke.
This model is configured with a centre trunnion (TC) mount for pivoting applications, supplied with the TCM1 bracket. The 25 mm piston rod runs through a PT1/2 port, and the built-in air cushion decelerates the load over a 29 mm cushion length. The body length A(SCJ) is 245 mm, making it a compact solution for heavy-duty adjustable-stroke tasks.
Airtac SCJ100 Standard Cylinder SCJ100X50-50TC Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X50-50TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 50 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 SCJ100X50-50TC Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position during machine commissioning without fabricating new stops. The 50 mm adjustment range on the 100 mm bore allows rapid, on-the-fly changes to dial in a process.
Format Changeovers
Quickly adapt a stopper or pusher cylinder to a new product size on a packaging line. The rear screw adjusts the stroke end, eliminating the need to swap cylinders between production runs.
Wear Compensation
Take up mechanical play or tooling wear in a clamping or pressing station. The adjustable stroke lets you advance the end position incrementally to maintain consistent clamping force over the tool's life.
Is the Airtac SCJ100 Standard Cylinder SCJ100X50-50TC the Right Cylinder?
Choose the SCJ100X50-50TC when you need to commission or fine-tune a 100 mm bore cylinder's end position within a 50 mm window. If your force requirement is lower, stepping down to the 80 mm bore (2513 N push at 0.5 MPa) can reduce air consumption. For applications needing a fixed, non-adjustable stroke, the standard SC100X50 is a simpler alternative.
This cylinder is a direct replacement for another AirTAC SCJ100X50-50 with a TC centre trunnion mount and PT ports. Ensure the adjustable range matches your setup. For strokes of 300 mm or more, always evaluate side-loading on the 25 mm rod; an external guide rail or a guided cylinder will protect the rod bearing and seals from premature wear.
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 SCJ100X50-50TC FAQ
At the standard 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. The push force is higher because the single rod reduces the effective piston area on the pull side. The maximum push force at 0.9 MPa is 7068 N.
It is a direct dimensional and functional replacement for any AirTAC SCJ100X50-50 cylinder with a TC centre trunnion mount and PT ports. You must match the 100 mm bore, 50 mm nominal stroke, 50 mm adjustable range, and mounting style exactly to ensure proper fit and function.
