The AirTAC AirTAC SDA100X50B 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 SDA100X50B is a double-acting single-rod compact cylinder engineered for heavy-duty linear motion within a minimal axial footprint. Delivering a substantial 3927 N push at 0.5 MPa, it utilizes a short riveted body design that saves mounting depth where standard round-body units cannot fit. This specific SKU features a male-thread piston rod end (M26x1.5) for secure mechanical load coupling.
The 100 mm bore features a hard-anodized inner wall and a fixed NBR bumper at each end to decelerate the stroke. Because this bumper is not an adjustable air cushion, high-energy cycles may require an external shock absorber. This model lacks a piston magnet, so it cannot host magnetic switches; adding an -S variant enables reed or electronic switch integration.

Provides the robust 3927 N push force required to eject heavy plastic automotive bumpers from large injection molding tools.
Executes short 50 mm stamping strokes for bending thick sheet metal enclosures where axial mounting space is highly restricted.
Raises loaded machining pallets weighing up to 200 kg, utilizing the male M26x1.5 thread for rigid fixture attachment.
When sizing this actuator, evaluate your force requirements bidirectionally. Stepping down, the SDA80 provides 2513.3 N push at 0.5 MPa; stepping up is not possible as 100 mm is the largest SDA bore. At 0.5 MPa, this 100 mm bore yields a safe working load of roughly 2356 N (about 60% of its 3927 N capacity) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. Confirm your ordering essentials: 100 mm bore, 50 mm stroke, PT3/8 port, male M26x1.5 rod thread, and no sensor magnet. Note that a plain SDA cylinder 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 pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 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 force is 801 kgf at 1.0 MPa.
It uses a fixed NBR bumper to decelerate the piston near stroke end, which is not an adjustable air cushion. It also does not hold position on air loss; for vertical loads, you must add an external rod lock or pilot-operated check valve.
