The AirTAC AirTAC MBL50X75CA 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 MBL50X75CA is a compact double-acting aluminum mini round cylinder engineered to deliver 981 N of push force at 0.5 MPa. Its 75 mm stroke is driven by a Ø16 mm carbon-steel piston rod plated with 20 μm hard chrome for high wear and corrosion resistance. The riveted rolling-packed barrel keeps the overall footprint small and lightweight for tight machine spaces, though it is not designed to be disassembled like a tie-rod body. This specific SKU features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads.
Inside, a heterogeneous two-way piston seal retains grease for long service life. End-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but is not an adjustable air cushion (for that, see the MBLC variant). Note that this configuration lacks the -S suffix, meaning it has no built-in magnet and cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Swings on a pin via its CA pivot back cover to drive the loom beater mechanism, using its 981 N push force at 0.5 MPa to pack weft threads tightly in a compact frame.
Actuates an angular sorting flap on a 75 mm stroke to redirect small totes on a conveyor line, where the fixed rubber bumper absorbs the repeated end-of-stroke impact.
Applies 881 N of pull force to hold a routing fixture in place within a dense electronics assembly cell, leveraging the lightweight riveted aluminum body to minimize moving mass.
If you need slightly less force, the MBL40 bore steps down to 628 N push at 0.5 MPa. If your application requires more power, the MBL63 steps up to 1558 N. This 50 mm bore uses a G1/4 port and an M14x1.5 rod-end thread. The default port thread form is PT, and the back cover is the CA pivot type, which should be paired with an SDB pivot bracket or clevis knuckle for your arcing load.
Because this model lacks a -S magnet, you cannot track rod position with a reed or solid-state switch. Keep in mind that the fixed rubber bumper only softens end-of-stroke impacts; it does not lock the rod. If your load must be held without live air pressure, the rod will drift or drop, so you will need an external rod lock or a pilot-operated check valve. For faster or heavier cycling, consider the MBLC variant with adjustable air cushioning.
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. The maximum theoretical force is 200 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper that cannot be adjusted (the MBLC variant offers adjustable air cushion). Additionally, this specific SKU lacks the -S suffix, so it has no built-in magnet and cannot support CMSG, DMSG, or EMSG sensor switches for position detection.
