The AirTAC AirTAC SDA40X100B Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 100mm 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 SDA40X100B 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 assembly significantly reduces axial mounting depth, making it highly effective for machinery where a standard round-body unit would protrude too far. This specific SKU features a male M14x1.5 threaded piston rod end, providing a robust mechanical coupling for your load.
The 40 mm bore houses a 16 mm hard-anodized piston rod and operates via PT1/8 ports at speeds between 30 and 500 mm/s. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy cycles. Note that this configuration lacks a piston magnet, so it cannot support magnetic position sensing.

Actuates routing flaps on logistics conveyor lines, utilizing the 100 mm stroke to shift parcels between sorting lanes efficiently.
Secures aluminum housings inside machining centers, where the male M14x1.5 rod threads directly into a custom jaw to hold parts against cutting forces.
Drives mechanical arms to fold corrugated box flaps prior to sealing, taking advantage of the short riveted body to fit within tight packaging frames.
When sizing this model, stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N, allowing you to fine-tune the force footprint precisely. For this 40 mm bore, a safe working load is approximately 377 N (about 60% of the 628.3 N capacity), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Keep in mind that a standard SDA cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 40 mm bore, 100 mm stroke, PT1/8 port, male M14x1.5 rod thread, and the absence of a sensor magnet.
Quick checklist
At 0.5 MPa, this double-acting 40 mm bore cylinder provides 628.3 N of push force and 527.8 N of pull force. At 0.7 MPa, push increases to 879.6 N. The theoretical maximum push is 128 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No. This model relies on a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, this specific SKU lacks the -S magnet option, meaning it cannot accommodate AirTAC reed or electronic switches for position sensing.
