Airtac MDD Multi-position Double Rod Cylinder MDD6X5S
The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD6X5S is a genuine MD multi-mount cylinder (double rod), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 14.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDD Multi-position Double Rod Cylinder MDD6X5S
The MDD6X5S is a genuine AirTAC multi-mount cylinder, a compact square-body actuator that fixes from 6 directions, front, back, left, right, top and bottom, so it bolts into almost any face of your fixture and units can be mounted side by side to save space. This double rod, double acting SKU pairs a 6 mm bore with a 5 mm stroke and a rod at each end, delivering about 10.6 N per rod side at 0.5 MPa (the rod-side figure for this bore), with a bumper providing the cushion at each end of travel. Slots around the body let magnetic switches snap on for end-position feedback.
Because this code ends in S, the magnet is included, so switches will detect piston position, which is the practical difference from the plain MDD6X5. It belongs to the MD standard family, meaning rod rotation is not actively prevented; specify the MK no-rotating family if your tool must stay square. The unit runs double acting at 30-500 mm/s on air filtered to 40 um, at 0.15-1.0 MPa (22-145 psi), with M5x0.8 PT ports. Exact dimensions for this stroke and any sizing check can be confirmed from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Match the bore to the load: at 0.5 MPa this 6 mm bore delivers roughly 14.1 N on the push side and 10.6 N on the pull side, so short, light-duty strokes are the fit. Choose MDD when you need working rods at both ends; choose double acting when you want powered extend and retract at 30-500 mm/s. The 5 mm stroke matches the compact covers this family is built around, so keep to short strokes rather than forcing a long stroke onto this body. The S suffix adds the magnet for switch sensing; drop it if you do not need feedback. Thread is PT as standard, with G optional for your fittings.
Applications
Micro-dispense trigger
In a bench-top dispenser, the short double rod press-taps a valve needle 5 mm for precise micro-drops, with magnet switches confirming the up and down stops.
Assembly station clamping
Banked side by side in a cramped multi-station fixture, each cylinder clamps a tiny component for 5 mm-class pressing or staking operations.
Indexing pin actuation
Mounted through the top face of a rotary dial, the cylinder raises and lowers an indexing pin between positions while the opposite rod end carries a limit flag.
FAQ
What is the difference between MDD6X5S and MDD6X5?
Only the magnet. The trailing S in MDD6X5S means this SKU includes the built-in magnet, so magnetic switches in the body slots can signal piston position. The plain MDD6X5 is otherwise identical but has no magnet and cannot be sensed. Both are double rod, double acting MD-family cylinders with a 6 mm bore and 5 mm stroke.
Where do I find the dimensions and side-load limits?
Overall dimensions depend on the specific stroke, and allowable side load is not a general figure, so both should be confirmed from the datasheet for this exact model before final mounting. What the multi-mount body does guarantee is fixing from all 6 directions and side-by-side installation, with high guide precision and no added lubricant required.
