The AirTAC SC50 Standard Cylinder SC50X700SCB is a genuine double-acting standard air cylinder with a Ø50mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X700SCB is a genuine AirTAC tie-rod 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. Its 50 mm bore and 700 mm stroke provide a long, linear working range, while the 20 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration at each end of travel.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear double clevis (CB) mounting for pivoting applications. The total extended body length is approximately 850 mm, making it suitable for installations where the cylinder needs to swing through an arc.

The 700 mm stroke and rear clevis mount allow the cylinder to pivot and push diverter arms on long conveyor lines, sorting packages or materials with 1374 N of force at standard plant pressure.
Ideal for controlling chute doors or linkage arms on farm machinery. The double clevis mount handles the swinging motion, while the magnet sensors confirm open/closed status to the operator.
Provides consistent, long-reach clamping in welding jigs. The adjustable air cushion softens the stop at 700 mm, reducing vibration that could affect weld quality, and the sensor confirms the clamp is engaged.
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a lighter, more compact solution is acceptable, the 40 mm bore offers 628 N. At a 700 mm stroke, ensure the rod is protected from side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
To replace an existing SC50X700SCB, match five points: 50 mm bore, 700 mm stroke, PT port thread, the CB rear double clevis mount (F-SC50CB), and the -S magnet for sensor compatibility. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa (5 bar) the cylinder pushes with 982 N. At the standard factory pressure of 0.7 MPa it delivers 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical pull force at 0.5 MPa is 825 N.
No. The SC50X700SCB is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve is centered, the piston rod can drift or drop. For load-holding, add a pilot-operated check valve or an external rod brake.
