The AirTAC Airtac SC50 Standard Cylinder SC50X970S is a genuine double-acting standard air cylinder with a Ø50mm bore and 970mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X970S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 970 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore, making it a standard-catalogue item. The built-in magnet (suffix -S) allows CMSG/DMSG/EMSG reed or solid-state sensors to be mounted directly on the barrel for piston-position feedback.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact noise. With a body length A of 150 mm, the total extended length is approximately 1120 mm. Operating pressure is 0.15-1.0 MPa, temperature range -20 to +70 °C with standard TPU/NBR seals.

The 970 mm stroke moves parts across wide conveyor gaps or between distant pick-and-place stations. The built-in magnet confirms full extension and retraction at each cycle.
Operates a sliding gate or product diverter on a packaging line. Sensor feedback from the -S magnet ensures the gate is fully open or closed before the next product arrives.
Pushes or aligns pallet layers in a stacking system. The adjustable cushion protects the mechanism from hard end-of-stroke impacts during high-speed operation.
The SC50 bore provides 982 N push at 0.5 MPa. If your application needs more force, step up to the SC63 (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 delivers 628 N. Always match replacement cylinders on five points: bore (50 mm), stroke (970 mm), port thread (PT), mounting accessory (none/basic here), and magnet option (this model has -S for sensor compatibility).
At 970 mm stroke, the 20 mm rod is relatively slender. Any significant side load can cause rod bending or premature bearing wear. Use an external linear guide or a guided-cylinder assembly to absorb transverse forces and protect the rod and seals.
Quick checklist
At 0.5 MPa (approx. 72 psi) the cylinder pushes with 982 N. At 0.7 MPa it delivers 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The pull force on the retract stroke is 825 N at 0.5 MPa due to the rod area.
Yes. The -S suffix means a magnet is built into the piston. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without any modification.
