The AirTAC AirTAC SDA25X35SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 35mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA25X35SB is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted assembly integrates the barrel, rear cover, piston, and rod into a highly shortened axial footprint, conserving valuable machine space where conventional round-body units cannot fit. The bore is hard-anodized and utilizes a two-way piston seal for reliable operation across a 30-500 mm/s speed range.
This specific configuration includes the -S option for a built-in piston magnet, enabling position detection via an AirTAC reed or electronic switch seated in the body grooves. The -B option provides a male M8x1.25 threaded piston rod end for straightforward load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize an external shock absorber for high-energy loads.

Provides the precise 245.4 N extension needed to push singulated circuit boards out of a routing fixture without damaging delicate surface-mount components.
Drives the mechanical arm that tucks minor flaps on corrugated shipping boxes prior to tape sealing, fitting neatly within tight conveyor side frames.
Acts as a rugged physical locator pin in a press feed line, extending 35 mm to square aluminum blanks before the stamping cycle begins.
When sizing this 25 mm bore unit, consider stepping down to the SDA20, which provides 157.1 N of push at 0.5 MPa, or moving up to the SDA32, which yields 402.1 N at the same pressure. A practical safe working load for this SDA25X35SB is roughly 147 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 12.5 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end rather than locking the load; an external rod lock or pilot-operated check valve is required for strict position holding. To order, confirm the 25 mm bore, 35 mm stroke, M5x0.8 port, integrated magnet (S), and male M8x1.25 rod thread (B).
Quick checklist
This 25 mm bore double-acting cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, increasing to 343.6 N push and 288.6 N pull at 0.7 MPa. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions in environments from -20 to +70 C.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; high-speed applications may need external shock absorption. Because it carries the -S magnet option, you can mount an AirTAC reed or electronic switch directly into the body grooves to detect end positions.
