The AirTAC Airtac SC50 Standard Cylinder SC50X930S is a genuine double-acting standard air cylinder with a Ø50mm bore and 930mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X930S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. With a 50 mm bore and a 20 mm diameter piston rod, this model is built for medium-duty linear tasks where consistent pneumatic power is required over a long working distance.
This specific configuration includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise end-of-stroke or mid-stroke position feedback. The 930 mm stroke is within the standard maximum range for the 50 mm bore, and the adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly to reduce impact noise and wear.

The 930 mm stroke pushes or pulls parts across wide conveyor gaps or between process stations, with sensor feedback confirming full extension and retraction for automated sequencing.
Delivers a consistent 982 N force to depress a dispensing head over a large panel. The built-in magnet allows sensors to signal the controller when the bead path is complete.
Operates a tall hopper gate or diverter chute. The adjustable cushion softens the stop at both ends of the 930 mm travel, protecting the gate structure from shock loads.
Choose the SC50 when your application needs around 982 N of force at standard plant pressure. If you require more force, stepping up to the SC63 provides 1559 N at the same 0.5 MPa. For lighter, faster cycling, the SC40 delivers 628 N. With a 930 mm stroke, the unsupported rod length is significant; any side load will create a bending moment on the 20 mm rod and rod bearing. Use an external linear guide or a guided cylinder configuration to absorb transverse forces and prevent premature seal and bearing wear.
For direct replacement, match five key points: 50 mm bore, 930 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
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 SC50 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve centers, the piston will drift. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
