About the Airtac SCJ32 Standard Cylinder SCJ32X100-50N
The SCJ32X100-50N is a 32 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke. A rear-cap adjusting screw provides up to 50 mm of stroke-end reduction, letting you dial in the exact 100 mm maximum stroke position without swapping the cylinder. The 12 mm diameter piston rod delivers 402 N of push force at 0.5 MPa, making it a compact solution for light-duty positioning tasks.
This model is fitted with NBR (nitrile) seals, a cost-effective choice for general industrial air service within the standard -20 to +70 °C temperature range. The cylinder body length (A dimension) is 182 mm, and it features a 21 mm air cushion for smooth deceleration. Ports are PT1/8, and the rod thread is M10x1.25. Genuine AirTAC build ensures consistent performance and long service life in high-cycle applications.
Airtac SCJ32 Standard Cylinder SCJ32X100-50N Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-50N |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 50 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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 1000 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCJ32 Standard Cylinder SCJ32X100-50N Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position during machine commissioning without needing to swap cylinders or machine custom stops. The 50 mm adjustment range on the SCJ32X100-50N allows rapid, on-machine optimization.
Wear Take-Up
In high-cycle clamping or pressing fixtures, use the rear adjusting screw to compensate for pad or tooling wear over time, maintaining consistent clamping force and position without reprogramming.
Format Changeover
Quickly adapt a stopper or diverter station for different product sizes on a packaging line. The operator can adjust the 100 mm stroke down by up to 50 mm to handle a new format in seconds.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-50N the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke actuator for light positioning. If your force requirement is borderline, stepping up to the 40 mm bore SCJ40 provides a significant jump to 628 N of push force at the same 0.5 MPa pressure. For applications where the stroke is fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a simpler, more economical alternative.
A direct replacement must match the 32 mm bore, 100 mm nominal stroke, and a 50 mm adjustment range. This NBR-sealed model is specifically for systems where nitrile compatibility is required. If you need to mount the cylinder, the SCJ32 accepts FA front flange or LB foot mounts, but the basic version here is supplied without them. For strokes over 300 mm, you must evaluate side-loading and consider an external guide to prevent rod bending.
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 SCJ32 Standard Cylinder SCJ32X100-50N FAQ
At the standard 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. The maximum push force at the 0.9 MPa operating limit is 724 N. The force is not affected by the stroke adjustment setting.
Yes, the SCJ32X100-50N is a direct dimensional and functional replacement for any AirTAC SCJ32 with a 100 mm stroke and 50 mm adjustment range. The key difference is the NBR seal material, which is suitable for standard temperature ranges and may have different chemical compatibility than the default TPU or optional Viton seals.
