The AirTAC Airtac SCJ50 Standard Cylinder SCJ50X1000-100S 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. Ø50mm bore, 1000mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ50X1000-100S is a double-acting, single-rod pneumatic cylinder that provides a nominal 1000 mm stroke, field-adjustable by up to 100 mm via a rear-cap screw. At 0.5 MPa, it generates 982 N of push force and 825 N on the pull stroke, making it a strong candidate for long-reach material handling and transfer lines. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This 50 mm bore cylinder uses a 20 mm diameter piston rod, PT1/4 ports, and an M16x1.5 rod thread for secure tooling attachment. Its tie-rod construction provides a serviceable, robust design, with an overall body length of 194 mm plus the 1000 mm stroke. The adjustable air cushion decelerates the piston smoothly, and the 100 mm adjustment range is ideal for commissioning large automation cells where the final stop position must be dialed in precisely without changing the cylinder.

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.
| 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.

The 100 mm adjustment screw lets technicians dial in the exact stop position on a 1000 mm transfer shuttle during initial line commissioning, eliminating the need to swap out hard stops or reposition the entire cylinder.
Ideal for pushing heavy totes or pallets across a 1-meter wide conveyor. The adjustable stroke allows operators to compensate for wear on the pusher plate or slight variations in conveyor width over time.
In high-cycle clamping fixtures, the mechanical end stop can wear down. The SCJ50X1000-100S allows maintenance teams to quickly extend the stroke end by a few millimeters to restore full clamping force without disassembling the tooling.
Choose the SCJ50X1000-100S when your application requires a 1000 mm reach with the ability to fine-tune the stroke end by up to 100 mm. If 982 N of push force at 0.5 MPa is insufficient, stepping up to the 63 mm bore provides 1559 N of push force. For applications where the stroke is fixed and never needs adjustment, the standard SC50X1000 offers a simpler, more compact alternative. This model is a direct replacement for another AirTAC SCJ50X1000-100S cylinder with a PT port and built-in magnet.
At this 1000 mm stroke, the piston rod is fully extended and inherently susceptible to side loading and bending. To prevent premature rod bearing wear or seal failure, you must guide the load externally with a linear rail or select a guided cylinder assembly. The built-in magnet simplifies sensor integration for position verification at both ends of this long stroke.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this cylinder delivers 982 N of push force and 825 N of pull force. The maximum push force at 0.9 MPa is 1767 N. The adjustable stroke screw does not alter the cylinder's force output.
Yes, if you need the ability to fine-tune the stroke end. The SCJ50X1000-100S shares the same bore, rod diameter, and port size as the SC50X1000. However, the SCJ body is slightly longer to accommodate the rear adjustment mechanism, so verify the available space in your machine.
