The AirTAC AirTAC SDA32X120SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 120mm 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 SDA32X120SB 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 conventional round-body units, saving valuable machine footprint. The bore is hard-anodized and uses a two-way piston seal for reliable performance across the 30-500 mm/s speed range.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male M10x1.25 threaded rod end (-B) for secure load coupling. End-stopping relies on a fixed NBR bumper to decelerate the piston, meaning it is not an adjustable air cushion. Operating pressure spans 0.15-1.0 MPa, with a maximum theoretical output of 82 kgf.

Deploys a 120mm stroke to push corrugated cartons off a main packaging conveyor belt onto secondary sorting lanes using 402.1 N of extend force.
Transfers cutting tool holders into a vertical machining center spindle, utilizing the male M10x1.25 rod end for rigid fixture attachment.
Actuates a sliding access gate on a multi-level pallet elevator, where the short riveted body conserves vertical shaft space.
Selecting this 32mm bore provides a safe working load of roughly 241 N (about 60% of the 402.1 N figure at 0.5 MPa), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA25 yields 245.4 N at 0.5 MPa; conversely, the SDA40 upgrades you to 628.3 N. To finalize your order, confirm the 120mm stroke, PT1/8 port, the -S magnet requirement, and the -B male M10x1.25 rod thread.
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 NBR bumper only decelerates the motion near the stroke end and does not act as a mechanical lock. For suspended or vertical loads that must be held without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting 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 capacity is 82 kgf at 1.0 MPa.
No, the SDA32X120SB 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 cycles, you should slow the approach speed or install an external shock absorber.
