About the Airtac SC100 Standard Cylinder SC100X450CB
The SC100X450CB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. Its 450 mm stroke is well within the 1500 mm maximum standard stroke for the 100 mm bore, making it a standard-configuration actuator with a 25 mm diameter piston rod and PT1/2 port threads.
This model is configured with a CB rear double clevis mount (fork/lug style, accessory F-SC100CB), allowing the cylinder body to pivot during operation. The adjustable air cushion at each end decelerates the piston smoothly over a 29 mm cushion length, reducing end-of-stroke impact. It uses standard TPU seals for a -20 to +70 °C temperature range and PT port threads.

Where the Airtac SC100 Standard Cylinder SC100X450CB Is Used
Agricultural Equipment Actuation
The 3927 N push force at 0.5 MPa and pivoting CB clevis mount suit heavy-duty agricultural mechanisms like harrow angle adjustment or bale handling gates, where the cylinder must swing through an arc.
Conveyor Diverters & Gates
With 450 mm of stroke and 7068 N of force at 0.9 MPa, this cylinder powers large material-handling diverters, chute gates, or pallet stops on wide conveyor lines in distribution centers.
Heavy Press Guard Doors
The double clevis mounting allows the cylinder to pivot as it raises or lowers a large safety guard door on a heavy stamping press, using the adjustable cushion to prevent slamming at the end of travel.
Is the Airtac SC100 Standard Cylinder SC100X450CB the Right Cylinder?
Choose the SC100 bore when your application needs roughly 4000 N of force at standard plant air pressure; the next step down is the 80 mm bore (2513 N at 0.5 MPa), while stepping up to the 125 mm bore provides 6136 N at 0.5 MPa. The 450 mm stroke is long enough that side-loading on the 25 mm rod should be evaluated—consider an external linear guide or a guided cylinder if the load is not purely axial.
For a direct replacement, match five attributes: 100 mm bore, 450 mm stroke, PT port thread, CB rear double clevis mounting, and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile cylinder, so dimensional interchangeability is limited to another AirTAC SC series unit of the same configuration.
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 SC100X450CB FAQ
At 0.5 MPa the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa push force rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. These values assume standard plant air and a correctly sized directional valve.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. Mounting dimensions, tie-rod spacing, and accessory interfaces differ. For a guaranteed fit, replace with another AirTAC SC100 cylinder matching the 450 mm stroke, PT ports, and CB rear double clevis configuration.
