The AirTAC AirTAC SDA40X60B Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 60mm 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 SDA40X60B is a double-acting single-rod compact cylinder engineered to deliver 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly unified structure, significantly reducing axial mounting depth compared to traditional round-body units. This space-saving footprint makes it exceptionally suited for machinery where installation envelopes are tight.
This specific SKU is configured with a male M14x1.5 piston rod thread for robust mechanical coupling to your load. The bore features a hard-anodized inner wall and a two-way piston seal, operating at speeds from 30 to 500 mm/s via a PT1/8 port. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

Actuates a routing flap on a logistics sorting line, using the 60mm stroke to redirect parcels efficiently within a narrow conveyor frame.
Secures aluminum housings during machining operations, utilizing the 628.3 N extend force to hold parts rigidly against cutting forces.
Drives the mechanical arms that fold minor flaps on automated case erectors, fitting easily into compact machine guarding.
When sizing this actuator, stepping down to the SDA32 bore yields 402.1 N of push force at 0.5 MPa, whereas stepping up to the SDA50 bore provides 981.7 N. The 40mm bore here offers a calculated safe working load of approximately 377 N (about 60% of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 40mm bore, 60mm stroke, PT1/8 port, male M14x1.5 rod thread (B), and note this unit lacks a piston magnet.
Quick checklist
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum push force is 128 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the SDA40X60BS variant to enable sensor mounting in the body grooves. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
