About the Airtac SC100 Standard Cylinder SC100X820CB
The AirTAC SC100X820CB is a double-acting tie-rod cylinder with a 100 mm bore and an 820 mm stroke, factory-equipped with a rear double clevis (CB) mount for pivoting applications. At 0.5 MPa it pushes with 3927 N and pulls with 3681 N, while at the maximum operating pressure of 0.9 MPa the push force reaches 7068 N, giving this actuator serious clamping and pressing capability.
This model uses a 25 mm diameter piston rod with an M20x1.5 rod-end thread and PT1/2 pneumatic ports. The adjustable air cushion at each end provides 29 mm of deceleration travel, helping to soften the piston impact even under the inertia of a long 820 mm stroke. The CB mount (accessory F-SC100CB) lets the cylinder pivot around a rear clevis pin, accommodating angular motion in linkages and press fixtures.

Where the Airtac SC100 Standard Cylinder SC100X820CB Is Used
Heavy-Duty Press & Clamp Fixtures
The 3927 N push force at 0.5 MPa and rear clevis pivot make the SC100X820CB ideal for welding clamps, assembly presses, and die-casting extractors where the cylinder must swing into position before applying high clamping force.
Pivoting Part Transfer & Sorting
With an 820 mm stroke and CB mount, this cylinder suits long-reach part pushers and diverters on packaging and palletising lines. The adjustable cushion absorbs the energy of moving heavy totes or pallets at the end of travel.
Large-Format Material Handling
Use the SC100X820CB to tilt or shift heavy sheet-metal blanks, timber panels, or moulded parts. The double clevis allows the cylinder body to pivot freely, preventing rod bending when the load path is not perfectly linear.
Is the Airtac SC100 Standard Cylinder SC100X820CB the Right Cylinder?
For applications needing more force, stepping up to the SC125 bore delivers 6136 N push at 0.5 MPa; for a lighter, faster actuator the SC80 bore provides 2513 N at the same pressure. The 820 mm stroke is well within the 1500 mm maximum standard stroke for the 100 mm bore, so no non-standard lead time applies.
At this stroke length, side loads and rod deflection must be managed carefully. The 25 mm rod is robust, but when the piston is fully extended an external linear guide or a guided-cylinder configuration is recommended if the load applies any off-axis force. For a direct replacement, match bore (100 mm), stroke (820 mm), PT1/2 port thread, rear double clevis (CB) mounting, and the absence of a magnet — this is a non-magnetic, TPU-sealed, PT-ported SC cylinder.
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 SC100 Standard Cylinder SC100X820CB FAQ
At 0.5 MPa the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa push rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
It is a direct replacement only for an AirTAC SC-series tie-rod cylinder with the same 100 mm bore, 820 mm stroke, PT1/2 ports, rear double clevis (CB) mount, TPU seals, and no built-in magnet. Because the SC is a tie-rod design and shorter than an ISO 15552 cylinder, it is not dimensionally interchangeable with ISO 15552 profile cylinders.
