About the Airtac SC100 Standard Cylinder SC100X70SLB
The SC100X70SLB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa, rising to 7068 N at 0.9 MPa. Its 70 mm stroke suits compact linear transfer and clamping operations where a large 100 mm bore is needed in a short envelope. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for end-of-stroke detection without external brackets.
This model includes an LB foot mount (F-SC100LB) for secure surface mounting on machine beds or frames. The 25 mm diameter piston rod and PT1/2 ports provide robust air flow. As a genuine AirTAC SC tie-rod cylinder, it offers adjustable air cushioning for smooth deceleration and a shorter overall length than an ISO 15552 profile cylinder.

Where the Airtac SC100 Standard Cylinder SC100X70SLB Is Used
Short-Stroke Clamping
The 70 mm stroke and 3927 N force at 0.5 MPa make this ideal for heavy-duty workpiece clamping in CNC machining centres or welding fixtures.
Material Stamping
Delivers up to 7068 N of push force at 0.9 MPa for short-travel stamping, embossing, or pressing operations on assembly lines.
Diverting Gates
The LB foot mount and magnetic piston sensors enable reliable actuation of heavy package diverters in conveyor systems with precise position feedback.
Is the Airtac SC100 Standard Cylinder SC100X70SLB the Right Cylinder?
Choose the SC100 bore when your application needs 3927 N at 0.5 MPa. If a smaller footprint is acceptable, the SC80 bore provides 2513 N at the same pressure. For loads exceeding 7000 N, consider stepping up to the SC125 bore (6136 N at 0.5 MPa). Always match replacement cylinders on five points: bore, stroke, port thread (PT), mounting accessory (LB), and magnet option (-S).
For strokes longer than 300 mm, side loading becomes a critical factor. Although this 70 mm stroke is inherently rigid, any application with a long unsupported rod should use an external guide or a guided cylinder to prevent rod bending and premature bearing wear.
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 SC100X70SLB FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC100 cylinder with matching stroke, PT ports, LB foot mount, and magnet option.
