The AirTAC AirTAC SDA32X35H Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 35mm 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 SDA32X35H is a double-acting single-rod compact cylinder engineered with a 32mm bore and 35mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. This specific SKU utilizes a fluororubber (FKM) seal variant, providing enhanced resistance to higher temperatures and oily environments compared to the standard NBR configuration.
The riveted body assembly drastically reduces axial mounting depth, making it ideal for machinery where space is strictly limited. End-of-travel deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion. Operating at speeds of 30-500 mm/s, the hard-anodized 32mm bore pairs with a 12mm piston rod and PT1/8 porting. Note that this base configuration lacks a piston magnet, so it cannot directly host magnetic position sensors.

Secures aluminum engine blocks during machining operations, utilizing the 402.1 N extend force and FKM seals to withstand cutting fluid exposure.
Deploys a 35mm stroke to tuck cardboard flaps on high-speed packaging lines, where the short riveted body minimizes frame interference.
Pushes parcels laterally on a logistics belt, taking advantage of the 30-500 mm/s speed range to maintain high throughput.
When sizing this actuator, stepping down to the SDA25 yields 245.4 N of push force at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. The 32mm bore offers a computed safe working load of roughly 241 N (about 60% of its 402.1 N capacity) and a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. To order, confirm the 32mm bore, 35mm stroke, PT1/8 port, female M6x1.0 rod thread, and the FKM seal option.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed bumper only decelerates the stroke near the end points and does not function as a locking brake. If your application requires static holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 32mm bore cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push force is 82 kgf at the 1.0 MPa pressure limit.
No. This model relies on fixed NBR bumpers for end-of-stroke deceleration, not an adjustable air cushion. Additionally, this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches; you would need the -S option for sensing capabilities.
