The AirTAC AirTAC MBL50X250SCA Mini Cylinder | 50mm Bore is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 250mm 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 MBL50X250SCA 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 and a 1374 N push at 0.7 MPa, making this 50 mm bore, 250 mm stroke variant ideal for moving heavier components in confined assemblies. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled like a tie-rod cylinder.
This specific SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing and angular loads. The integrated -S magnet allows CMSG reed or DMSG/EMSG electronic sensor switches to detect rod position. The 16 mm carbon steel rod is hard-chrome plated (20 um) for wear resistance, and the heterogeneous two-way piston seal retains grease for a long service life.

The CA pivot back cover and 981 N thrust suit swinging diverter arms on packaging lines, absorbing angular misalignment during part routing.
Provides the 250 mm stroke needed to push heavy pallets between parallel conveyors, with the integrated magnet confirming full extension via a DMSG sensor.
Ejects filled tote boxes from a compact machine cell, using the 0.7 MPa 1374 N push force to overcome box weight and sliding friction.
If 981 N at 0.5 MPa is too much force, step down to the 40 mm bore (628 N push); if you need more power, step up to the 63 mm bore (1558 N push). This model uses a G1/4 port, a 16 mm rod with an M14x1.5 thread, and a PT tapered port thread. The CA pivot back cover is essential here for angular movements, pairing with an SDB pivot bracket or clevis.
Because the stroke is 250 mm, the 16 mm rod has limited side-load tolerance and can bend under lateral stress—use an external guide or consider the MBLD double-rod type for anti-rotation. Note that the fixed rubber bumper softens end-of-stroke impact but does not lock the load; if air pressure drops, the rod drifts. For heavier end-loads needing softer stops, select the MBLC adjustable air cushion variant.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa it pushes 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. The stroke is 250 mm, well within the 500 mm standard limit for this 50 mm bore.
The base MBL uses a fixed rubber bumper on the end caps to soften impact, not an adjustable cushion screw. If your application moves heavier masses at high speeds and requires end-stroke deceleration tuning, upgrade to the MBLC variant which features an adjustable air cushion.
