The AirTAC SC50 Standard Cylinder SC50X75S is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 75 mm stroke suits medium-travel clamping, pressing, and sorting stations where sensor feedback is required.
A built-in magnet (denoted by the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for precise end-of-stroke detection. The 20 mm diameter piston rod and PT1/4 ports are standard for the 50 mm bore, with an adjustable air cushion absorbing 21 mm of travel at each end to reduce impact noise.

The built-in magnet enables CMSG/DMSG sensors to confirm clamp position, making the SC50X75S ideal for automated workholding fixtures where control logic requires end-of-stroke verification.
With 75 mm of stroke and 982 N of force at 0.5 MPa, this cylinder reliably actuates product diverters on packaging lines. The magnetic piston allows sensors to track gate open/closed status.
The 50 mm bore generates up to 1767 N at 0.9 MPa for light press-fit operations. Sensor feedback confirms the rod has reached full extension during each insertion cycle.
Select the SC50X75S when 75 mm of linear travel and integrated position sensing are needed. If the 982 N push force at 0.5 MPa is insufficient, stepping up to the 63 mm bore provides 1559 N at the same pressure. For side-loaded or guided applications, pair the cylinder with an external linear guide to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five points: 50 mm bore, 75 mm stroke, PT1/4 ports, the built-in magnet (-S), and the basic (no bracket) mounting style. Only another AirTAC SC tie-rod cylinder with the same specifications will provide dimensional interchangeability.
Quick checklist
At 0.5 MPa, the cylinder produces 982 N extending and 825 N retracting. At 0.7 MPa, the extending force rises to 1374 N. The maximum operating force at 0.9 MPa is 1767 N.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped onto the barrel's tie-rod slots for non-contact position detection.
