The AirTAC SC50 Standard Cylinder SC50X660 is a genuine double-acting standard air cylinder with a Ø50mm bore and 660mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X660 is a double-acting tie-rod cylinder with a 50 mm bore and a non-standard 660 mm stroke. At 0.5 MPa air pressure it generates 982 N of push force and 825 N pull force, rising to 1767 N push at the maximum operating pressure of 0.9 MPa. The 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This cylinder is built with a body length A of 150 mm, giving a total extended length of approximately 810 mm. The PT1/4 port and M16x1.5 rod thread are standard for the SC50 series. Because the 660 mm stroke exceeds the 1200 mm maximum standard stroke for this bore, this unit is a made-to-order configuration. It uses TPU seals with a standard operating temperature range of -20 to +70 °C and does not include a magnet.

Moves components 660 mm across a conveyor or workstation. The 20 mm rod and adjustable cushion handle the extended stroke smoothly at speeds up to 800 mm/s.
Feeds material strips or blanks into a stamping press. The 982 N push force at 0.5 MPa provides consistent advancement, with the tie-rod construction absorbing repetitive impact.
Pushes totes or cartons off a gravity roller lane onto a sortation conveyor. The long 660 mm stroke reaches across wide lane gaps without complex linkages.
The SC50X660 suits applications needing the 982 N push force of a 50 mm bore over a long 660 mm reach. If your load requires more force, stepping up to a 63 mm bore provides 1559 N push at 0.5 MPa. For lighter, faster cycles, the 40 mm bore offers 628 N. When replacing this cylinder, match five points: 50 mm bore, 660 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet.
At this 660 mm stroke, the unsupported piston rod is exposed to bending under side loads. Fit an external linear guide or rod support to prevent rod bearing wear and seal failure. For vertical or offset loads, a guided cylinder or external slide mechanism is strongly recommended.
Quick checklist
At 0.5 MPa the push force is 982 N and the pull force is 825 N. At 0.7 MPa push reaches 1374 N, and at the maximum operating pressure of 0.9 MPa it delivers 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke, so it is not dimensionally interchangeable. Only replace another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT1/4 port, and basic mounting.
