The AirTAC AirTAC MBL50X50SCA Mini Cylinder | 50mm Bore 50mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 50mm 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 MBL50X50SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. At 0.5 MPa it delivers 981 N of push force and 881 N of pull force, making this 50 mm bore, 50 mm stroke unit ideal for moving heavier small-footprint loads. The riveted rolling-packed barrel keeps the body light but means it is a sealed assembly, not designed to be unbolted or rebuilt like a standard tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for rod position detection using AirTAC CMSG, DMSG, or EMSG sensor switches, and features a CA pivot back cover. The CA clevis allows the cylinder body to swing on a pin, accommodating arcing or angular loads. The carbon-steel piston rod features 20 um hard-chrome plating for wear resistance, and the base end relies on a fixed rubber bumper to soften end-of-stroke impacts.

Swings a lightweight sorting gate on a packaging line using 981 N of push force, where the CA pivot back cover absorbs the angular load during arc movement.
Drives a dowel pin into an aluminum housing on an assembly fixture, using the 50 mm stroke and DMSG electronic sensor to confirm insertion depth.
Actuates a stopping flap for pallets entering a machining cell, relying on the compact riveted aluminum body to fit within the conveyor frame.
Select this 50 mm bore when you need substantially more force than the 32 mm version (402 N push at 0.5 MPa) but want a smaller footprint than a 63 mm bore (1558 N push). If your application requires precise end-of-stroke deceleration for heavier moving masses, step up to the MBLC variant which offers adjustable air cushioning instead of the standard fixed rubber bumper. Remember that a plain cylinder cannot hold a load if air pressure drops; use an external pilot-operated check valve or rod lock for fail-safe position holding.
For replacement matching, verify the 50 mm bore, 50 mm stroke, G1/4 port size, PT thread form, CA pivot back cover, and the -S magnet. Because the stroke is 50 mm, side-load bending on the Ø16 mm rod is minimal, but ensure the CA clevis pin is aligned correctly to prevent binding.
Quick checklist
This double-acting cylinder provides 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum force of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL50X50SCA uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier loads, you need the MBLC variant.
