About the Airtac SC50 Standard Cylinder SC50X42CB
The SC50X42CB is a 50 mm bore, 42 mm stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for compact linear moves.
This model includes a rear double clevis (CB) mounting, part F-SC50CB, allowing the cylinder body to pivot during operation. The standard PT1/4 port thread and TPU seals suit filtered-air systems operating from -20 to +70 °C. It is a genuine AirTAC tie-rod cylinder built for repeatable short-stroke actuation.

Where the Airtac SC50 Standard Cylinder SC50X42CB Is Used
Part Diverter Gate
The rear clevis mount lets the cylinder pivot as it extends, making it ideal for actuating a small diverter flap on a packaging conveyor with a 42 mm stroke.
Clamp & Fixture Actuation
Delivers 982 N of clamping force at 0.5 MPa, suitable for a short-throw pneumatic toggle clamp or welding fixture where the body needs to swing into position.
Hopper Door Operator
Pivots a small discharge door on a seed or grain hopper. The double clevis handles the arc motion, and the 21 mm cushion absorbs the door's closing impact.
Is the Airtac SC50 Standard Cylinder SC50X42CB the Right Cylinder?
The 50 mm bore suits mid-force tasks—step down to a 40 mm bore (628 N at 0.5 MPa) if space or air consumption is a concern, or up to 63 mm (1559 N at 0.5 MPa) when more push is needed. The 42 mm stroke is within the standard range for this bore (max 1200 mm).
When replacing, match five points: 50 mm bore, 42 mm stroke, PT1/4 ports, rear double clevis mounting (F-SC50CB), and non-magnetic piston. The CB clevis suits pivoting applications; ensure the pivot pin is aligned to avoid side-loading the rod bearing.
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 SC50X42CB FAQ
At 0.7 MPa operating pressure, the 50 mm bore produces a theoretical push force of 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, accounting for the 20 mm rod area.
This specific model (SC50X42CB) is supplied with a rear double clevis bracket (F-SC50CB). For rigid foot mounting, order the LB suffix instead. The clevis is designed for pivoting applications and should not be welded or fixed solid.
