The AirTAC SC50 Standard Cylinder SC50X755S is a genuine double-acting standard air cylinder with a Ø50mm bore and 755mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X755S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a non-standard 755 mm stroke. Its 20 mm diameter piston rod and PT1/4 ports deliver a push force of 982 N at 0.5 MPa, rising to 1767 N at the maximum operating pressure of 0.9 MPa.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for contactless position sensing. The adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends, and the TPU seals provide reliable operation from -20 to +70 °C.

The 755 mm stroke moves components between distant conveyor stations or work cells, with the magnet enabling end-of-stroke confirmation via barrel-mounted sensors.
Provides the extended linear motion needed to divert products on wide packaging lines, where the 982 N push force at standard plant pressure handles medium-weight diverters.
Used in a vertical push configuration to raise or position light to medium bins and totes, with the adjustable cushion softening the stop at both ends of the long travel.
For applications needing slightly more force, stepping up to the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If a shorter, standard stroke is acceptable, the SC50 series offers strokes up to 1200 mm in 25 mm increments, which may reduce lead time compared to this non-standard 755 mm length. At this extended stroke, the unsupported piston rod is susceptible to bending under side loads; an external linear guide or a guided cylinder should be used to protect the rod bearing and seals.
When replacing this cylinder, match five key points: 50 mm bore, 755 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting style.
Quick checklist
At 0.5 MPa, the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No, 755 mm is a non-standard stroke for the 50 mm bore SC series, where the maximum standard stroke is 1200 mm. Non-standard strokes are made-to-order, so lead times may be longer than for standard strokes like 750 mm or 800 mm.
