The AirTAC AirTAC SDA50X100SB Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 100mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X100SB is a double-acting, single-rod compact cylinder engineered with a 50 mm bore and 100 mm stroke. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa, making it well-suited for medium-duty industrial positioning. The riveted body design significantly reduces axial mounting depth compared to traditional round-body units, saving valuable machine footprint.
This specific configuration includes the -S magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, plus the -B male M18x1.5 piston rod end for secure mechanical load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads.

Actuates routing gates on high-speed logistics conveyor lines, using the 100 mm stroke to push parcels cleanly between sorting lanes.
Drives the sealing head down onto filled corrugated boxes, applying steady clamping pressure for adhesive application.
Raises lightweight product tiers within an assembly cell, lifting up to 50 kg payloads vertically with a controlled 2:1 safety margin.
When sizing this unit, consider stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. For the SDA50X100SB, the computed safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 100 mm stroke, PT1/4 port, built-in magnet, and male M18x1.5 rod thread.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its limits rather than acting as a lock. If your application requires strict load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, push is 1374.4 N and pull is 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa, which is the maximum operating pressure.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed cycles, add an external shock absorber. It does not hold position on air loss; use an external rod lock or pilot-operated check valve if load holding is required.
