The AirTAC AirTAC SDA32X20B Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 20mm 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 SDA32X20B is a double-acting, single-rod compact 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 footprint compared to conventional round-body designs.
This specific SKU includes a male M10x1.25 thread on the 12 mm piston rod for direct load coupling, alongside a PT1/8 port. The bore is hard-anodized, and end-stops rely on a fixed NBR bumper rather than an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot host magnetic switches.

Secures aluminum workpieces in a machining center vise, utilizing the 402.1 N extend force to lock the part firmly against locators during milling operations.
Deploys the 20 mm stroke to swiftly fold corrugated box flaps prior to sealing tape application, fitting neatly into tight packaging line frames.
Pushes molded plastic parts out of an injection mold cavity, using the male M10x1.25 rod end to thread on a custom ejection paddle.
When sizing this 32 mm bore unit, evaluate your force needs bidirectionally: stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For the current bore, a safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. To finalize your order, confirm the 20 mm stroke, PT1/8 port, and the male M10x1.25 rod thread. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the stroke near its end and does not function as a locking brake. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and travels at speeds of 30-500 mm/s.
No, this specific SKU does not include the -S magnet option, so the machined grooves around the body cannot be utilized for sensing. You would need to select the SDA32X20BS variant to equip an AirTAC reed or electronic switch. Additionally, the end caps use a fixed NBR bumper to decelerate the piston, not an adjustable air cushion.
