The AirTAC AirTAC SDA50X65B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 65mm 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 SDA50X65B is a double-acting single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its short riveted body design significantly reduces axial mounting depth compared to traditional round-body units, making it highly effective for machinery where spatial footprint is restricted. The unit operates within a speed range of 30-500 mm/s.
This specific SKU features a male M18x1.5 thread on the 20 mm piston rod for robust mechanical coupling to your load. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this configuration lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Pushes medium-weight cartons off a sorting line using the 981.7 N extend force, with the short riveted body fitting neatly between tight conveyor frames.
Raises or lowers 50 kg workpiece platforms vertically, benefiting from the 20 mm male-thread rod for a rigid load coupling that resists play.
Drives mechanical arms to fold heavy cardboard flaps prior to sealing, where the fixed NBR bumper effectively absorbs the impact at the 65 mm stroke end.
When sizing this unit, consider stepping down to the SDA40 which provides 628.3 N of push force at 0.5 MPa, or moving up to the SDA63 which yields 1558.6 N at the same pressure. For this 50 mm bore, the safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Be aware that a standard cylinder drifts when air pressure is lost or a valve is centered; the fixed bumper only decelerates the piston near stroke end and does not function as a locking brake. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required. Confirm your ordering essentials: 50 mm bore, 65 mm stroke, PT1/4 port, no magnet, and the male M18x1.5 rod thread.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 981.7 N of push force and 824.7 N of pull force. At 0.7 MPa, the push increases to 1374.4 N. The theoretical maximum push force is 200 kgf at 1.0 MPa.
No. This model uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, because it lacks the -S magnet code, it cannot accommodate reed or electronic switches.
