The AirTAC AirTAC SDA63X35SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 35mm 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 SDA63X35SB is a double-acting, single-rod compact cylinder engineered to deliver a substantial 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, conserving axial mounting depth in tight machine layouts. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic performance.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The -B option equips the 20 mm rod with a male M18x1.5 thread, providing a robust mechanical coupling for heavy loads. Deceleration at stroke ends relies on fixed NBR bumpers rather than adjustable cushions.

Secures heavy cast iron engine blocks during machining operations, utilizing the 2182.1 N extend force at 0.7 MPa to prevent workpiece vibration.
Actuates the release mechanism in automated palletizing lines, where the short 35 mm stroke and space-saving riveted body fit within constrained frame dimensions.
Drives the ejection plate for plastic components, using the male M18x1.5 rod end to thread directly into the mold tooling for positive mechanical engagement.
When sizing this actuator, evaluate your force requirements carefully. If you need less thrust, the adjacent SDA50 provides 981.7 N of push at 0.5 MPa; stepping up to the SDA80 yields 2513.3 N at the same pressure. Based on the 1558.6 N output, the computed safe working load is roughly 935 N (60% capacity), translating to a vertical lift capability of about 79.4 kg with a 2:1 safety margin.
Confirm your ordering essentials: 63 mm bore, 35 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the integrated sensor magnet. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only slows the piston near the end of travel. To suspend a load securely without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
It uses fixed NBR bumpers at each end to decelerate the piston, which is not an adjustable air cushion. For high kinetic energy loads, add an external shock absorber. It does not hold position naturally; if air is lost, the piston drifts, requiring a pilot-operated check valve or rod lock to maintain a load.
