The AirTAC SC50 Standard Cylinder SC50X850SH is a genuine double-acting standard air cylinder with a Ø50mm bore and 850mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X850SH is a double-acting single-rod 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. Its 50 mm bore, 20 mm diameter piston rod, and 850 mm stroke make it a capable mid-range actuator for tasks requiring a long linear reach.
This model is equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and Viton (FKM) seals (-H suffix) that extend the operating temperature range to 0–150°C, making it suitable for high-heat environments. The adjustable air cushion (21 mm) at each end decelerates the piston to reduce end-of-stroke impact, and the PT1/4 port threads are standard.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow this cylinder to operate reliably in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150°C, a range that would degrade standard TPU seals.
The 850 mm stroke and 1767 N of force at 0.9 MPa are ideal for pushing heavy parts onto a conveyor or transferring tooling between distant stations on an assembly line.
The integrated magnet allows for clean, external mounting of CMSG/DMSG sensors to provide precise end-of-stroke or mid-stroke position feedback to a PLC without additional brackets.
For applications needing more force, stepping up to a 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. If a shorter, more compact solution is acceptable, the 40 mm bore (SC40) offers 628 N at the same pressure. This 850 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
When replacing this cylinder, match five key points: 50 mm bore, 850 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. For this long 850 mm stroke, be aware that the unsupported piston rod is susceptible to bending under side loads. Use an external linear guide or a guided cylinder to protect the rod bearing and ensure reliable service life.
Quick checklist
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 825 N. The maximum push force at 0.9 MPa is 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with the same stroke, port thread, magnet option, and seal material.
