The AirTAC AirTAC SDA63X50SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 50mm 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 SDA63X50SB is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an ultra-short unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable long-term operation.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, and a male M18x1.5 threaded rod end (-B) for secure load coupling. End-of-travel impact is managed by a fixed NBR bumper, which decelerates the piston near the stroke limits but is not an adjustable air cushion. Operating speed ranges from 30-500 mm/s, making it highly versatile for mid-weight industrial motion tasks.

Provides the 1558.6 N extension force needed to secure heavy machining pallets onto a CNC worktable, utilizing the short riveted body to fit within tight machine envelopes.
Actuates a heavy-duty routing arm on a logistics conveyor to deflect parcels up to 79.4 kg, relying on the 50 mm stroke and male M18x1.5 rod for a rigid linkage.
Raises and lowers an assembly line lift gate, where the built-in magnet enables precise reed or electronic switch detection at the upper and lower limits without adding external sensors.
When sizing this model, evaluate your force requirements carefully. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa; stepping up, the SDA80 yields 2513.3 N at the same pressure. For the SDA63X50SB, a safe working load is approximately 935 N (about 60% of the 1558.6 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking the load. For suspended or vertical loads, incorporate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 50 mm stroke, PT1/4 port, built-in magnet (S), and male M18x1.5 rod thread (B).
Quick checklist
This 63 mm bore cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not a field-adjustable air cushion, so external shock absorbers are recommended for high-speed approaches. Additionally, it does not function as a brake—if air is lost or the valve is centered, the piston will drift, requiring an external rod lock or pilot-operated check valve to hold a suspended load.
