About the Airtac SC50 Standard Cylinder SC50X458S
The SC50X458S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration across the full 458 mm stroke.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The cylinder body length A is 150 mm, giving an extended length of approximately 608 mm, and it operates on filtered air from -20 to +70 °C with TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X458S Is Used
Material Stop & Divert Gates
The 458 mm stroke and magnetic piston sensing suit conveyor line diverters where mid-stroke and end-of-stroke confirmation is required to sequence product flow.
Automated Clamping & Fixturing
Delivers 982 N of consistent clamping force at 0.5 MPa. The built-in magnet enables sensor feedback to verify clamp engagement before a machining or welding cycle starts.
Long-Reach Pusher & Ejector
Ideal for pushing bins or cartons off a line. The 458 mm reach clears wide conveyors, and the adjustable cushion absorbs impact energy at the end of the stroke.
Is the Airtac SC50 Standard Cylinder SC50X458S the Right Cylinder?
Choose the SC50 when the 40 mm bore's 628 N force at 0.5 MPa is marginal; step up to the 63 mm bore (1559 N at 0.5 MPa) if the load exceeds 980 N. The 458 mm stroke is within the 1200 mm maximum standard stroke for bore 50. For strokes over 300 mm, avoid side loads on the unsupported 20 mm rod—use an external linear guide or a guided cylinder to prevent rod bending and premature bearing wear. To match this exact configuration for replacement, confirm five points: 50 mm bore, 458 mm stroke, PT1/4 port thread, basic mounting (no bracket), and the -S magnetic piston for sensor compatibility.
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 SC50X458S FAQ
At 0.5 MPa the cylinder produces 982 N pushing and 825 N pulling. At 0.7 MPa it delivers 1374 N push. The theoretical maximum force at 1.0 MPa is 200 kgf (1960 N), though the recommended operating range is 0.15–1.0 MPa.
Yes. The -S suffix indicates a magnet is built into the piston. You can mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's sensor groove to detect piston position without additional brackets.
