The AirTAC MBL Aluminum Alloy Mini Cylinder MBL40X300-CA is a genuine double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, 1/8" air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL40X300-CA is a double-acting aluminum mini round cylinder engineered for compact spaces requiring a 300 mm stroke. It delivers a robust 628 N push force at 0.5 MPa, making it well-suited for moving heavier jigs or workpieces over longer travel distances. 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 SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing or angular loads during extension. The carbon-steel piston rod is hardened with 20 um chrome plating for wear resistance. Note that because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Pushes raw bar stock through a spindle guide tube over a 300 mm travel, utilizing the 628 N push force and CA clevis to self-align during the feed cycle.
Actuates a pivoting routing gate on a packaging conveyor, where the clevis mount absorbs side-shock and the long stroke clears large parcel cartons.
Lifts a stretch film roll assembly up a vertical mast, relying on the 40 mm bore's 528 N pull force to lower the carriage smoothly.
This 40 mm bore provides 628 N push and 528 N pull at 0.5 MPa. If your application requires less force, step down to the 32 mm bore (402 N push); for heavier lifting, step up to the 50 mm bore (981 N push). The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, so for faster cycling or heavier moving masses, consider the MBLC variant which offers adjustable air cushioning.
With a 300 mm stroke, the Ø16 mm rod is highly susceptible to side-load bending. The CA pivot back cover on this unit helps safely manage angular loads by allowing the cylinder body to swing. For rigid linear guidance over this long travel, pair the cylinder with external linear guides or consider the MBLD double-rod anti-rotation type. Remember that this cylinder will not hold its load if air pressure is lost; use an external pilot-operated check valve for drop prevention.
Quick checklist
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It uses a 1/8" port, a Ø16 mm piston rod, and an M12x1.25 rod-end thread.
No, because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption, not an adjustable cushion; you would need the MBLC variant for adjustable air cushioning.
