AirTAC SDA Series Compact Cylinders
The AirTAC SDA series is a compact, thin-body double-acting air cylinder built for tight axial spaces, spanning 12-100 mm bores with a short riveted body design.
inventory_2408 models availableSeries Overview
The AirTAC SDA series is a standard single-rod, double-acting compact (thin) air cylinder. A short riveted body joins the barrel, rear cover, piston and rod. This design minimizes overall length, saving axial mounting depth versus a round-body cylinder. It is not a tie-rod cylinder and not an ISO 15552 profile cylinder.
The range covers 10 bores from 12 to 100 mm. Rod diameter scales from 6 mm on the 12 mm bore up to 32 mm on the 100 mm bore. Ports are M5x0.8 on 12-25 mm bores, PT1/8 on 32/40 mm, PT1/4 on 50/63 mm, and PT3/8 on 80/100 mm. Push force at 0.5 MPa spans about 57 N to 3927 N. Theoretical max push at 1.0 MPa spans about 12 kgf to 801 kgf.
Shared design features include a hard-anodized bore, aluminum body and covers, and a two-way piston seal. Deceleration uses a fixed NBR bumper at each end (no adjustable air cushion). Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, temperature range is -20 to +70 C, and speed is 30-500 mm/s. The -S option adds a magnet for AirTAC magnetic switches. Variants include SSA (single acting push), STA (single acting pull), SDAD (double rod), SDAJ (adjustable stroke), and SDAT/SDAW (duplex). The JIS compact equivalent is the ACQ series.

Typical Applications
Package Diverting Gates
Short-stroke SDA cylinders fit between conveyor rollers to actuate diverting pop-up gates, using the compact riveted body to save axial space in tight transfer sections.
Carton Flap Folding
The 12-25 mm bore range provides the low force and short stroke needed to fold small carton flaps in high-speed packaging lines without crushing the material.
PCB Clamping Fixtures
The hard-anodized bore and double-acting design deliver smooth, repeatable clamping on electronics assembly fixtures where minimal protrusion is critical.
How to Choose the Right Model
Choose the SDA series when axial length is tight and stroke requirements are short. Standard max stroke is 50 mm for small bores and up to 120-130 mm for 25-100 mm bores. Match the bore to your load: larger bores provide higher force but require larger ports. Select the SDAJ variant if you need adjustable stroke, or SDAD for double-rod anti-rotation. Pick the -S magnet option if you need position sensing.
Step out of the SDA series to a neighbouring AirTAC family if you need an ISO 15552 interface, heavy side-load guidance, or longer strokes. Before submitting an RFQ, confirm these 5 points: 1) bore size, 2) required stroke, 3) port thread and rod thread (female blank or male B option), 4) mounting style, and 5) magnet (-S) requirement.

- ✓ Stroke and available mounting space
- ✓ Port / thread type (PT / NPT / G)
- ✓ Sensor / magnet option (-S)?
- ✓ Side load — consider a guided model
Frequently Asked Questions
The SDA series spans 10 bores from 12 to 100 mm. Rod diameter ranges from 6 mm to 32 mm. Push force at 0.5 MPa spans about 57 N on the 12 mm bore up to 3927 N on the 100 mm bore. Theoretical max push at 1.0 MPa spans about 12 kgf to 801 kgf.
The standard SDA is double-acting single-rod. SDAD is double-rod for higher anti-rotation resistance. SDAJ offers adjustable stroke. SSA is single-acting push, STA is single-acting pull, and SDAT/SDAW are duplex cylinders. Choose based on your stroke and space requirements.
No. The SDA series uses a fixed NBR bumper at each end to decelerate the piston. It does not have adjustable air cushions. The cylinder is double-acting and does not hold position if air pressure is lost; a mechanical lock or pilot check valve is required for load holding.
No. The SDA is a compact metric cylinder with a short riveted body, not an ISO 15552 profile or tie-rod cylinder. It is designed for tight axial mounting spaces. The JIS compact equivalent in the AirTAC range is the ACQ series.
