The AirTAC AirTAC MBL50X75SCA Mini Cylinder | 50mm Bore 75mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 75mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL50X75SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa, making it well-suited for mid-range actuation tasks requiring a 75 mm stroke. The riveted rolling-packed barrel design keeps the body lightweight and small, prioritizing a minimal footprint over ISO 6432 interchangeability.
This specific SKU includes a built-in magnet (-S) for use with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position, and a CA pivot back cover that allows the cylinder to swing on a pin for arcing or angular loads. The carbon-steel piston rod features a 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Swings a yarn guide arm through an arcing path using the CA pivot back cover, applying 981 N of push force at 0.5 MPa to tension and shift weaving threads.
Folds corrugated carton flaps in a compact packaging line where the 75 mm stroke and built-in magnet confirm flap closure via a DMSG solid-state sensor.
Pivots a diverter gate on a parcel conveyor using the CA clevis, using the 200 kgf maximum theoretical force to redirect heavy boxes at high speed.
If your application requires less force, step down to the 40 mm bore, which provides 628 N of push force at 0.5 MPa. For heavier demands, the 63 mm bore offers 1558 N of push force. Keep in mind that this base MBL model relies on a fixed rubber bumper; if your 75 mm stroke involves high moving masses, consider the MBLC variant for adjustable air cushioning. Additionally, a plain double-acting cylinder does not hold its load if air pressure is lost or the valve is centered—the rod will drift. Use an external rod lock or pilot-operated check valve if position holding is required.
This exact replacement configuration features a 50 mm bore, 75 mm stroke, G1/4 port with default PT tapered thread, an M14x1.5 rod-end thread, a CA pivot back cover, and a built-in magnet. The 50 mm bore uses a Ø16 mm rod, which offers limited side-load tolerance; for arcing loads, rely on the CA clevis and an SDB pivot bracket rather than rigidly mounting the body.
Quick checklist
This 50 mm bore cylinder provides 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa. It operates at speeds between 30-800 mm/s.
No, the base MBL50X75SCA uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable air cushion. If your application requires adjustable cushioning for heavier moving loads, you should select the MBLC variant.
