The AirTAC AirTAC SDA50X80SBH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 80mm 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 SDA50X80SBH is a double-acting single-rod compact cylinder engineered for tight axial footprints. Its riveted assembly keeps overall length minimal where a standard round-body unit would not fit. At 50 mm bore, it generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific configuration includes a male M18x1.5 piston rod, a built-in magnet for position sensing, and fluororubber (FKM) seals for enhanced thermal and oil resistance.
The bore inner wall is hard-anodized for longevity, and the piston relies on a two-way seal. End-stopping is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add an external shock absorber for high-energy cycles. Grooves around the body accept AirTAC reed or electronic switches to track the piston via the internal magnet.

Drives the mechanical arms that tuck inner flaps on high-speed corrugated box erectors, utilizing the 80 mm stroke and 981.7 N output to clear heavy cardboard reliably.
Actuates routing gates on logistics merge lines, where the short riveted body saves axial depth within tight conveyor frame structures and the FKM seals resist ambient grease.
Pushes stripper plates away from plastic injection molds, leveraging the male M18x1.5 rod end for secure mechanical coupling under repetitive cyclic loads.
When sizing this unit, compare its 981.7 N push at 0.5 MPa against adjacent bores: stepping down to the SDA40 yields 628.3 N, while stepping up to the SDA63 provides 1558.6 N. Based on the 0.5 MPa figures, the safe working load is roughly 589 N (about 60 percent of capacity), translating to a vertical lift capability of approximately 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 80 mm stroke, PT1/4 port, male M18x1.5 rod thread, magnet, and FKM seal. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a lock or brake. Use an external rod lock or pilot-operated check valve if the application requires load holding.
Quick checklist
This 50 mm bore double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a braking lock. For high-speed cycles, add external shock absorption. The built-in magnet allows tracking via AirTAC reed or electronic switches mounted in the body grooves.
