The AirTAC SDA63X30S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 30mm 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 SDA63X30S is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N of push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into a remarkably short axial profile, conserving valuable machine footprint where a conventional round-body unit would be too deep. The bore is hard-anodized, and the piston relies on a two-way seal for reliable actuation.
This specific configuration includes the S option, equipping the piston with a built-in magnet for direct compatibility with AirTAC reed or electronic switches housed in the body grooves. End-stopping is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be specified for high-energy cycles. Operating at 30-500 mm/s, it features a 20 mm rod and a PT1/4 port.

Provides robust 1558.6 N extension force to eject dense plastic parts from confined mold tooling, utilizing the short riveted body to fit within tight press platens.
Drives a heavy-duty routing gate on a packaging line, where the 20 mm rod withstands lateral impact forces and the built-in magnet tracks arm position via electronic switches.
When sizing this 63 mm bore actuator, evaluate your force margins carefully. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa, whereas stepping up to the SDA80 yields 2513.3 N at the same pressure. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; achieving true position holding requires an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 30 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required S magnet option.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 1558.6 N of push force and 1401.5 N of pull force. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at the 1.0 MPa operating pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for fast cycles, add external shock absorbers. Furthermore, it lacks a locking mechanism, so a vertical load will drift if air is lost unless you install a pilot-operated check valve or external rod lock.
