The AirTAC AirTAC SDA100X50SN Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 50mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X50SN is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial envelope. By utilizing a riveted assembly that integrates the barrel, rear cover, piston, and rod, this unit achieves a notably shorter mounting depth than conventional round-body actuators. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, driven through a PT3/8 port.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, which seat cleanly into the grooves machined around the body. The 32 mm piston rod features a female M18x1.5 thread, and end-of-stroke deceleration is handled strictly by fixed NBR bumpers rather than adjustable pneumatic cushions.

Provides the high 3927 N push force required to eject dense plastic parts from heavy injection molding machinery, saving machine footprint.
Delivers robust clamping pressure for holding heavy gauge sheet metal in position during industrial press brake bending operations.
Actuates heavy material feeding mechanisms in automated metal stamping lines, utilizing the 32 mm rod to handle substantial side-load resistance.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N, offering a safe working load of roughly 2356 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. If your application demands maximum thrust, the 100 mm bore reaches a theoretical 801 kgf at 1.0 MPa.
Keep in mind that a standard double-acting cylinder will drift and cannot hold a load if air pressure drops or the directional valve is centered; the fixed NBR bumper only decelerates the piston near stroke end and does not function as a mechanical brake. For suspended or vertical loads, incorporate an external rod lock or pilot-operated check valve. To finalize your order, confirm the 100 mm bore, 50 mm stroke, PT3/8 port, female M18x1.5 rod thread, and the integrated magnet.
Quick checklist
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, the SDA series uses fixed NBR bumpers at each end to decelerate the piston near the stroke limits; these are not field-adjustable air cushions. Additionally, the cylinder does not lock or hold position on air loss, so an external shock absorber or rod lock is required for high-energy or suspended loads.
