About the Airtac SC50 Standard Cylinder SC50X1400SLB
The SC50X1400SLB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and an extended 1400 mm non-standard stroke, it uses a 20 mm diameter piston rod and PT1/4 ports, making it suitable for long-reach linear actuation tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and comes fitted with an LB foot mount (F-SC50LB) for stable surface installation. The adjustable air cushion at each end, with a 21 mm cushion length, decelerates the piston smoothly, while the standard TPU seals provide reliable operation from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1400SLB Is Used
Long-Stroke Material Rejection
Pushes defective products off a wide conveyor line where a 1400 mm reach is required to clear the belt, using the LB foot mount for rigid, low-profile installation.
Vertical Panel Lifting
Raises and lowers large access panels or guards in industrial machinery, with the sensor magnet confirming full-open and full-closed positions for safety interlocks.
Extended Bin Gate Actuation
Operates a slide gate at the bottom of a large hopper or silo, where the long stroke is needed to fully retract the gate, and the foot mount absorbs the operational thrust.
Is the Airtac SC50 Standard Cylinder SC50X1400SLB the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, standard stroke is acceptable, the SC50 series offers strokes up to 1200 mm from stock. Given the 1400 mm stroke, the unsupported rod length is significant; external guides or a guided cylinder are strongly recommended to prevent rod bending and bearing wear under side loads.
When replacing an existing cylinder, ensure a match across five key points: 50 mm bore, 1400 mm stroke, PT1/4 port thread, the LB foot mounting accessory, and the integrated magnet for sensor compatibility. This is a tie-rod design, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC50 tie-rod cylinder.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X1400SLB FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No, the maximum standard stroke for an SC50 cylinder is 1200 mm. A 1400 mm stroke is a non-standard, made-to-order length. For such a long stroke, an external guide mechanism is essential to protect the 20 mm rod from side-load bending.
