About the Airtac SCJ50 Standard Cylinder SCJ50X130-100S
The SCJ50X130-100S is a 50 mm bore double-acting single-rod cylinder with a rear adjusting screw that provides up to 100 mm of field-adjustable stroke reduction, letting you fine-tune the end position from 130 mm down to 30 mm without swapping the cylinder. At 0.5 MPa it delivers 982 N push and 825 N pull, making it a capable mid-range actuator for tasks that need frequent end-stop changes.
This model includes a built-in magnet (-S suffix), so standard CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The 20 mm rod, PT1/4 ports, and 21 mm air cushion are standard for the 50 mm SCJ family, and the body length A(SCJ) is 194 mm—slightly longer than the fixed-stroke SC due to the rear adjuster housing.
Airtac SCJ50 Standard Cylinder SCJ50X130-100S Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X130-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 130 mm |
| Stroke adjustment | Up to 100 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 21 mm |
| Max stroke | Up to 1200 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCJ50 Standard Cylinder SCJ50X130-100S Is Used
Commissioning & Setup
Dial in the exact stroke end position during machine commissioning without cutting brackets or adding hard stops. The 100 mm screw range lets technicians quickly adapt to as-built dimensions.
Product Changeover
Adjust the push stroke for different product sizes on a packaging or sorting line. Operators can reset the stop in seconds when switching between short and tall box formats.
Wear Compensation
Take up mechanical wear in clamping or pressing fixtures over time. The rear screw lets maintenance teams restore the original clamped position without replacing the cylinder or tooling.
Is the Airtac SCJ50 Standard Cylinder SCJ50X130-100S the Right Cylinder?
Choose this 50 mm bore when the 40 mm bore's 628 N push at 0.5 MPa is marginal; if you need more force, the 63 mm bore delivers 1559 N at the same pressure. The 100 mm adjustment range suits processes with wide format changes or where the stroke must be dialled in over a long commissioning window. If the stroke is fixed and never needs field adjustment, a standard SC50X130 is a simpler, slightly shorter alternative.
For replacement, match an AirTAC SCJ cylinder with 50 mm bore, 130 mm nominal stroke, 100 mm adjust range, PT1/4 ports, basic mounting, and the -S magnet option. At 130 mm nominal stroke, rod bending from side load is not a primary concern, but for any off-axis force, guide the load externally or consider a guided cylinder.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ50 Standard Cylinder SCJ50X130-100S FAQ
At 0.5 MPa, the 50 mm bore generates 982 N push and 825 N pull. Maximum push force at the 0.9 MPa operating limit is 1767 N. The adjustable stroke screw changes only the end position, not the cylinder's force output.
Yes, if the mounting and porting match. The SCJ50 body is slightly longer (194 mm A-length) to house the adjusting screw. Ensure you have clearance for the rear adjuster and order the same PT1/4 port and -S magnet configuration to maintain sensor compatibility.
