The AirTAC AirTAC MBL50X75SU 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 MBL50X75SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides a push force of 981 N and a pull force of 881 N across its 75 mm stroke. The U suffix designates a flat-end rear cover for rigid, fixed mounting, while the integrated -S magnet enables position detection.
Unlike tie-rod bodies, this cylinder uses a riveted rolling-packed barrel where the covers are crimped to the tube, creating an exceptionally light and compact footprint that is not designed to be disassembled. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion. Because this SKU includes the magnet, you can mount CMSG reed or DMSG and EMSG solid-state switches directly onto the body for precise end-of-stroke signaling.

Uses the 981 N push force at 0.5 MPa to deflect medium-weight cardboard cartons on a narrow-belt logistics sorting line where space is strictly limited.
Secures aluminum engine blocks during machining, relying on the 20 um chrome-plated rod to withstand repetitive clamping cycles without surface wear.
Acts as a rigid physical stop for incoming wooden pallets on a low-profile assembly conveyor, using the flat-end U cover for stable foot-style mounting.
This 50 mm bore generates 981 N of push force at 0.5 MPa. If your application requires less force, step down to the 40 mm bore, which yields 628 N of push. If you need more power, the 63 mm bore provides 1558 N. For tasks needing faster cycle speeds with heavier loads, consider the MBLC variant, which replaces the standard fixed rubber bumper with an adjustable air cushion to soften end-of-stroke impacts.
The base MBL50X75SU cannot hold a load in place if air pressure is lost or the valve is centered; the rod will drift. Use an external pilot-operated check valve or rod lock if position holding is critical. Replacement matching requires a 50 mm bore, 75 mm stroke, G1/4 port size, PT thread form, U flat-end back cover, and the built-in magnet.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL50X75SU uses a fixed rubber bumper to absorb end-of-stroke impacts and does not feature an adjustable cushion screw. If your application requires adjustable air cushioning to handle heavier moving loads or faster speeds, you should select the MBLC variant instead.
