The AirTAC AirTAC SDA32X35SB 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 SDA32X35SB 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 significantly reduces axial mounting depth compared to round-body units, making it highly effective for machinery with tight spatial footprints. The 32 mm bore features a hard-anodized inner wall and operates on a PT1/8 port.
This specific configuration includes a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches fitted into the body grooves, and a male M10x1.25 threaded rod end (-B) for direct load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize external shock absorbers for high-energy cycles. The 12 mm piston rod operates within a 30-500 mm/s speed range.

Drives the Z-axis plunge on a printed circuit board depaneling router, utilizing the 35 mm stroke and male M10x1.25 rod to securely hold a high-speed spindle over the workpiece.
Actuates a routing flap on a conveyor belt to sort glass containers, relying on the 402.1 N push force to overcome friction and the compact body to fit within the narrow guard panels.
Indexing pusher that advances raw material stock into the collet, where the short 35 mm stroke provides precise linear positioning without consuming valuable operator workspace.
When sizing this actuator, stepping down to an SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to an SDA40 provides 628.3 N. The 32 mm bore offers a calculated safe working load of roughly 241 N (about 60% of its 402.1 N capacity), translating to a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact SKU: 32 mm bore, 35 mm stroke, PT1/8 port, magnetic piston, and male M10x1.25 rod thread. Note that a standard SDA cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For suspended loads, 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 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 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 a speed range of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston; it is not an adjustable air cushion, so external shock absorbers are recommended for high-speed loads. This model includes a magnetic piston for use with AirTAC reed or electronic switches, and features a male M10x1.25 rod thread instead of the standard female M6x1.0.
