The AirTAC SC50 Standard Cylinder SC50X800SLB is a genuine double-acting standard air cylinder with a Ø50mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X800SLB is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). With a 50 mm bore and an 800 mm stroke, it is sized for medium-duty linear transfer and clamping tasks where a moderate force envelope is sufficient.
This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, plus an LB foot mount (F-SC50LB) for stable axial surface mounting. The 20 mm diameter rod and PT1/4 ports provide a robust connection, while the adjustable air cushion decelerates the piston smoothly over a 21 mm cushion length.

Pushes or diverts medium-weight packages and components on conveyor lines, leveraging the 800 mm reach and 982 N force at standard shop air.
Holds workpieces securely in machining or welding fixtures, with the magnet confirming full extension via a barrel-mounted sensor.
Actuates gates or pusher plates in logistics sorting systems, where the long 800 mm stroke covers wide conveyor beds.
For applications needing more force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, more compact actuator is acceptable, the 40 mm bore delivers 628 N. At an 800 mm stroke, ensure the rod is guided externally if significant side loads are present, as a long unsupported 20 mm rod is susceptible to bending under lateral force.
When replacing this cylinder, match five key points: 50 mm bore, 800 mm stroke, PT1/4 port thread, the LB foot mounting accessory, and the built-in magnet for sensor compatibility. This ensures a direct replacement for another AirTAC SC50 tie-rod cylinder with the same configuration.
Quick checklist
At 0.7 MPa (7 bar) operating pressure, the push force on the extend stroke is 1374 N. The pull force on the retract stroke is 825 N at the same pressure.
Yes, for any stroke of 300 mm or more, an external guide or guided cylinder configuration is strongly recommended if the load applies any side force. The 20 mm rod can bend under lateral loads when fully extended, leading to premature seal and bearing wear.
