The AirTAC AirTAC SDA32X70 Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 70mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA32X70 is a double-acting, single-rod compact air cylinder engineered to deliver 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston and rod into an ultra-short unit, drastically reducing axial mounting depth compared to conventional round-body designs. The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable friction-free operation.
This specific 70 mm stroke configuration utilizes a 12 mm piston rod and PT1/8 porting. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Because this SKU lacks the -S magnet option, it cannot host magnetic reed or electronic switches for position sensing.

Pushes small to medium cardboard cartons across sorting lanes at 402.1 N of extend force, fitting neatly within the tight side-clearance of conveyor frames.
Extracts depaneled circuit boards from a routing fixture using a 70 mm travel, relying on the hard-anodized 32 mm bore to resist wear in dusty environments.
Lowers a liquid filling nozzle into bottles on a rotary packaging line, where the short riveted body minimizes the vertical headspace required above the carousel.
When sizing this actuator, stepping down to the SDA25 provides 245.4 N of push force at 0.5 MPa, while stepping up to the SDA40 yields 628.3 N at the same pressure. For the SDA32X70, a safe working load is approximately 241 N (about 60% of the 402.1 N capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. To finalize your order, confirm the 32 mm bore, 70 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the absence of a piston magnet.
Keep in mind that a standard double-acting cylinder will not hold a load if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only slows the stroke near its end without acting as a mechanical lock. If your application demands strict position holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 32 mm bore cylinder provides 402.1 N push and 345.6 N pull. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.
No. This specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You must select the SDA32X70S variant to enable position sensing. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
