The AirTAC AirTAC MBL50X20U Mini Cylinder | 50mm Bore 20mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 20mm 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 MBL50X20U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 981 N of push force and 881 N of pull force across its 20 mm stroke. The U suffix denotes a rigid flat-end back cover, making it ideal for straightforward, fixed-foot mounting where angular rod movement is not required.
This model features a riveted rolling-packed barrel where the covers are crimped to the tube, creating a lightweight, permanently sealed body that is not designed for field teardown. It relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG position sensors.

Uses the 981 N push force to positively eject dense plastic parts from tight injection molding tooling cavities.
Short 20 mm stroke rapidly folds heavy cardboard flaps in compact packaging machinery where space is strictly limited.
Punches out a rigid diverter arm on a high-speed conveyor belt to redirect heavy parcels into sorting lanes.
For slightly lower force, the MBL40 bore yields 628 N push at 0.5 MPa, while stepping up to the MBL63 provides 1558 N. This U-type flat-end rear cover mounts rigidly; if your mechanism requires angular alignment, switch to the CA pivot back cover. The fixed rubber bumper halts the rod smoothly but does not lock the load—without live air pressure, the rod drifts, so add an external rod lock for vertical holding. Porting is G1/4 with an M14x1.5 rod-end thread.
Quick checklist
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push force is 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. The double-acting speed range is 30-800 mm/s.
No, this specific SKU lacks the -S magnet suffix, meaning no CMSG, DMSG, or EMSG sensor switch can be fitted. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; for adjustable air cushioning, you must select the MBLC variant.
