The AirTAC SC50 Standard Cylinder SC50X865S is a genuine double-acting standard air cylinder with a Ø50mm bore and 865mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X865S 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 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 865 mm stroke, making it suitable for medium-force linear tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the tie-rod barrel for precise end-of-stroke or mid-position sensing. The body length A is 150 mm, giving a total extended length of approximately 1015 mm.

The 865 mm stroke and sensor-ready design allow this cylinder to operate long-travel diverter gates on conveyor lines, with magnetic switches confirming the gate's open or closed position for automated sortation.
Provides consistent, medium-force linear motion for traversing a glue head across large panels. The built-in magnet enables multi-position sensing to control adhesive bead start and stop points accurately.
Drives the film carriage vertically with a long, smooth stroke. The adjustable air cushion prevents hard stops at the top and bottom of the cycle, while sensors confirm carriage position for the wrap count.
For applications needing more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If a shorter, more rigid setup is acceptable, the 40 mm bore offers 628 N. At this 865 mm stroke, the rod is fully supported by the guide bushing and piston, but side loads must be managed; use an external guide rail or a guided cylinder for off-axis forces to prevent rod bending.
To match this cylinder for replacement, verify five points: 50 mm bore, 865 mm stroke, PT port thread, basic mounting (no brackets), and the -S magnet for sensor compatibility. This is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder.
Quick checklist
At the standard 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. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so it is not a direct dimensional replacement. It should be used to replace another AirTAC SC tie-rod cylinder or a unit with matching bore, stroke, port thread, mounting, and magnet specifications.
