The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X80 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 80mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 528 N each way at 0.5 MPa. Fixed rubber bumper.
The AirTAC MBLD40X80 is a double-acting, double-rod aluminum mini cylinder featuring a 40mm bore and 80mm stroke. Because a Ø16mm carbon-steel rod protrudes from both end covers, the effective annulus area is identical on extend and retract. This yields exactly 528N of force both ways at 0.5 MPa, ensuring perfectly balanced motion for pushing and pulling. The 80mm stroke is optimal for short-indexing slides and mid-range transfer tasks.
This riveted rolling-packed barrel uses a heterogeneous two-way grease-retaining piston seal and a fixed rubber bumper at each end. A defining physical trait of the double-rod layout is that overall length equals the base body length plus 2x stroke; you must leave rear-rod clearance for the protruding shaft to mount a cam or position flag. Note that this specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG electronic sensors for position detection.

Double-rod overall length = A + 2 × stroke — leave clearance for the rear rod. MBLD/MBLCD mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 108 kgf |
A rod on both piston faces makes the annulus area equal, so extend and retract force (and speed) are the same. Actual usable force is lower due to friction.

Drives a dual-sided lifting fork in a PCB handling machine, using the 528N equal force and 80mm stroke to raise boards smoothly without rotational sagging.
Indexes a wafer cassette out of an oven using the rear rod end to trip a mechanical limit flag, capitalizing on the twin-rod anti-rotation properties.
Folds corrugated carton flaps simultaneously on a packaging line, where the perfectly matched extend and retract speeds prevent jamming during high-speed cycling.
Stepping down to the 32mm bore drops the bidirectional force to 346N at 0.5 MPa, while stepping up to the 50mm bore increases it to 881N. Choose this 40mm model when a job demands roughly 528N of balanced push/pull force. Unlike the single-rod MBL which offers greater forward push, the MBLD sacrifices that for equal annulus force and dual-side guidance. If your application requires adjustable air cushioning rather than fixed rubber bumpers, select the MBLCD variant instead.
Mounting is restricted to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for this double-rod body. To match this cylinder for replacement, verify the 40mm bore, 80mm stroke, G1/4 port, PT tapered thread, and lack of a magnet. Remember that the fixed rubber bumper softens end-impact but does not lock the rod; a plain MBLD drifts without live air, so use an external locking device for static holding.
Quick checklist
Because the piston rod occupies both sides, the push and pull forces are identical. It delivers 528N at 0.5 MPa and 739N at 0.7 MPa in both directions. The maximum theoretical force is 108 kgf at 1.0 MPa.
A rod exits both ends, providing equal annulus area for matched speed and force both ways, plus allowing a cam or flag on the rear shaft. This specific MBLD40X80 SKU has no built-in magnet (-S), so it cannot accept CMSG reed or DMSG/EMSG electronic sensors.
