The AirTAC AirTAC SDA100X70 Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 70mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X70 is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. It delivers a substantial 3927 N push and 3524.9 N pull at 0.5 MPa, providing robust linear actuation where space is restricted.
This model features a hard-anodized 100 mm bore and a sturdy 32 mm piston rod. End-stops are managed by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. This SKU ships without a piston magnet, so position sensing is not supported without the -S option.

Thread: PT standard. Related SDA-family variants: SSA (single-acting push), STA (single-acting pull), SDAD (double rod), SDAJ (adjustable stroke), SDAT (duplex), SDAW (duplex-end).
Ejects heavy formed metal panels from stamping presses, utilizing the 5497.8 N extend force at 0.7 MPa to overcome material friction.
Actuates large molding tooling separation plates where the short riveted body prevents interference with the machine clamp frame.
Raises and lowers heavy diverting gates on packaging palletizers, handling loads safely up to 2356 N during continuous shifting operations.
Selecting this 100 mm bore provides a safe working load of roughly 2356 N, translating to a vertical lift capacity of about 200.2 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa, but as the largest standard bore, there is no larger SDA option for higher demands.
When ordering, confirm the 70 mm stroke, PT3/8 port, and female M18x1.5 rod-end thread. Note that a plain SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; integrating an external rod lock or pilot-operated check valve is required for secure position holding.
Quick checklist
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push force is 801 kgf at the 1.0 MPa pressure limit.
This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches without the -S option. Additionally, it uses a fixed NBR bumper to decelerate at stroke end, not an adjustable air cushion, so external shock absorption is advised for high speeds.
