About the Airtac SC100 Standard Cylinder SC100X850SCB
The SC100X850SCB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With an 850 mm stroke and a 25 mm diameter piston rod, this model is built for demanding linear applications requiring substantial force over a long travel distance.
This configuration includes a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-stroke position feedback. The CB suffix specifies a rear double clevis mount (F-SC100CB), allowing the cylinder to pivot during operation, which is ideal for articulating linkages. The body length is 188 mm, resulting in a total extended length of approximately 1038 mm.

Where the Airtac SC100 Standard Cylinder SC100X850SCB Is Used
Material Handling Pusher
The 3927 N force at 0.5 MPa effortlessly pushes heavy totes or pallets off a conveyor line. The 850 mm stroke provides the reach needed for wide transfer stations.
Heavy-Duty Clamping
Generates up to 7068 N of clamping force for large weld fixtures or assembly jigs. The rear clevis mount allows the cylinder to swing into position for part loading.
Agricultural Equipment Actuation
Controls chutes, gates, or diverters on bulk handling equipment. The magnetic piston enables sensor feedback to confirm open/closed status in dusty environments.
Is the Airtac SC100 Standard Cylinder SC100X850SCB the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 80 mm bore SC80 series, which provides 2513 N at 0.5 MPa. If your load requires a higher safety margin, the 125 mm bore delivers 6136 N at the same pressure. Given the 850 mm stroke, side loads on the 25 mm rod must be avoided; use an external guide rail or rod alignment coupler to prevent rod bending and premature bearing wear.
To ensure a correct replacement, match these five points: 100 mm bore, 850 mm stroke, PT port thread, CB rear double clevis mounting, and the built-in magnet for sensor compatibility. This tie-rod cylinder is dimensionally interchangeable only with an identical AirTAC SC series model.
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 SC100X850SCB FAQ
The theoretical push force at 0.5 MPa is 3927 N. At the standard factory air pressure of 0.7 MPa, it outputs 5497 N, and at the maximum operating pressure of 0.9 MPa, it reaches 7068 N. The pull force on retraction is slightly lower due to the rod area, providing 3681 N at 0.5 MPa.
No. As a standard double-acting cylinder, the SC100X850SCB will drift or drop if air pressure is exhausted or the directional valve is centered. For load-holding applications, you must add an external pilot-operated check valve or a mechanical rod lock.
