About the Airtac SC50 Standard Cylinder SC50X175SLB
The SC50X175SLB delivers 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. Its 175 mm stroke suits medium-reach clamping, pressing, and material-transfer tasks where a compact tie-rod body is preferred.
This model includes a built-in magnet (suffix S) for direct mounting of CMSG/DMSG/EMSG sensors, plus an LB foot mount (F-SC50LB) for rigid surface installation. The 20 mm diameter piston rod and PT1/4 ports provide a balanced flow path, while the adjustable air cushion decelerates the 175 mm stroke smoothly.

Where the Airtac SC50 Standard Cylinder SC50X175SLB Is Used
Conveyor Diverter Gates
The 175 mm stroke and 982 N push force at 0.5 MPa reliably actuates medium-width diverter gates on packaging and sortation conveyors. The LB foot mount provides a stable, bolted-down installation.
Light Press-Fit Assembly
Delivers up to 1767 N at 0.9 MPa for pressing bushings, bearings, or dowels into light alloy housings. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Pallet Stop & Lift
Ideal for pallet-handling stations where a 175 mm lift or stop stroke is needed. The adjustable cushion protects the cylinder and load from impact at the end of travel.
Is the Airtac SC50 Standard Cylinder SC50X175SLB the Right Cylinder?
For higher force at the same pressure, step up to the 63 mm bore (1559 N push at 0.5 MPa); for a lighter, faster actuator, the 40 mm bore (628 N push at 0.5 MPa) may suffice. The 175 mm stroke is well within the 1200 mm maximum standard stroke for bore 50.
When replacing, match five points: 50 mm bore, 175 mm stroke, PT1/4 port thread, LB foot mounting, and the built-in magnet for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X175SLB FAQ
At 0.5 MPa, push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder matching bore, stroke, port thread, mounting, and magnet option.
