The AirTAC SC50 Standard Cylinder SC50X830S is a genuine double-acting standard air cylinder with a Ø50mm bore and 830mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X830S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), driven by a 20 mm diameter piston rod. With an 830 mm stroke and a body length A of 150 mm, this actuator is built for linear movements requiring mid-range force and integrated position sensing.
The built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact end-of-stroke or mid-position detection. Its adjustable pneumatic cushion (21 mm) decelerates the piston smoothly, and the standard PT1/4 port threads ensure straightforward pneumatic connections.

Pneumatically actuated stop gate on a conveyor line, using the 830 mm stroke to raise and lower a barrier. The built-in magnet provides sensor feedback to confirm gate position.
Transfer unit moving parts between distant stations. The 50 mm bore provides sufficient force for medium-weight components, while the magnet enables mid-stroke sensing for multi-position logic.
Assisted lifting device in a warehouse, using the 982 N push force to elevate bins. The adjustable cushion protects the cylinder at the top of the stroke under varying loads.
For applications needing slightly more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore offers 628 N. At an 830 mm stroke, the 20 mm rod is extended significantly; ensure side loads are minimal or use an external guide to prevent rod bending and premature bearing wear. For direct replacement, match the 50 mm bore, 830 mm stroke, PT1/4 ports, basic mounting, and the -S magnet option.
Quick checklist
At 0.5 MPa operating pressure, 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 increases to 1767 N.
No. The SC50X830S is a double-acting cylinder and does not lock or hold position when pressure is exhausted. If load holding is required, you must add a pilot-operated check valve or an external mechanical rod lock.
