The AirTAC AirTAC SDA63X35SBH 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 SDA63X35SBH is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its short riveted body significantly reduces axial mounting depth compared to conventional round-body units, offering a highly space-efficient footprint for tight machine layouts. The hard-anodized bore and two-way piston seal ensure durable, long-lasting performance.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It features a male-thread piston rod (-B) sized at M18x1.5 for secure mechanical load coupling, and utilizes high-temperature fluororubber (-H) seals. End-stopping is handled by a fixed NBR bumper, which decelerates the piston near stroke end rather than acting as a lock or adjustable air cushion.

Drives ejection pins in plastic injection molding machines where the short riveted body saves axial depth and the FKM seals withstand elevated ambient heat.
Folds corrugated cardboard flaps on high-speed palletizing lines, utilizing the 1558.6 N extend force to cleanly close heavy-duty packaging materials.
Pushes sheet metal blanks into precise alignment within stamping presses, leveraging the rigid 20 mm rod and male M18x1.5 thread for solid load engagement.
When sizing this unit, evaluate your force requirements carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. For the SDA63X35SBH, a safe working load is approximately 935 N (about 60% of the 1558.6 N figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a brake. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 35 mm stroke, PT1/4 port, S magnet, male M18x1.5 rod, and FKM seals.
Quick checklist
This 63 mm bore double-acting cylinder provides 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. It operates on filtered air at 0.15-1.0 MPa, runs at 30-500 mm/s, and functions in environments from -20 to +70 C.
It relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not an adjustable air cushion, so external shock absorbers may be needed for high-energy cycles. The built-in magnet allows you to track position using AirTAC reed or electronic switches mounted in the body grooves.
