The AirTAC AirTAC SDA32X90SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 90mm 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 SDA32X90SB 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 body assembly merges the barrel, rear cover, piston, and rod into a highly integrated unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. Driven by filtered air over a 30-500 mm/s speed range, it provides robust linear motion within a tight machinery footprint.
This specific configuration includes an S option for a built-in piston magnet, allowing seamless integration with AirTAC reed or electronic switches via the body's peripheral grooves. The B option equips the 12 mm piston rod with a male M10x1.25 thread for secure mechanical coupling, while the PT1/8 ports manage pneumatic flow. End-stopping relies on a fixed NBR bumper that decelerates the payload, meaning it is not an adjustable air cushion and external shock absorbers should be added for high-energy cycles.

Provides 402.1 N of extension force at 0.5 MPa to secure aluminum housings inside CNC machining centers, utilizing the male M10 thread for direct fixture attachment.
Uses the 90 mm stroke to fold corrugated cardboard flaps on automated packaging lines, where the short riveted body conserves valuable conveyor side-frame space.
Pushes molded plastic parts out of injection molds, relying on the built-in magnet to trigger an electronic switch for precise end-of-stroke confirmation.
Selecting this 32 mm bore actuator involves balancing your thrust requirements with spatial limits. If you need less force, stepping down to the SDA25 provides 245.4 N of push at 0.5 MPa; conversely, moving up to the SDA40 yields 628.3 N at the same pressure. With a 90 mm stroke, this model maximizes the compact body's reach while remaining within the 130 mm standard limit, yielding a safe working load around 241 N (roughly 60% of the 0.5 MPa push figure) and a vertical lift capacity of about 20.5 kg using a 2:1 safety margin. When ordering, confirm the 32 mm bore, 90 mm stroke, PT1/8 porting, male M10x1.25 rod end, and the magnetic switch readiness.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops or the directional valve centers. The piston will drift, and the fixed NBR bumper only decelerates the stroke near the end points rather than locking the load. If your application demands strict position holding without live pressure, you must incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 32 mm bore double-acting cylinder generates 402.1 N of push and 345.6 N of pull at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions across a 30-500 mm/s speed range.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy loads, you should add an external shock absorber or slow the approach speed. Additionally, it does not hold its load if air is lost; an external rod lock or pilot-operated check valve is required for fail-safe position holding.
