Steel Stirring Shaft, Φ8 mm × 500 mm, for LT400/500 Stirrers

The Yamato 231384 is a steel stirring shaft, 8 mm diameter by 500 mm long, for Yamato LT400 and LT500 overhead laboratory stirrers. It chucks directly into the stirrer's Φ8 mm drill chuck, providing the drive shaft that carries an impeller or paddle down into the vessel for mixing viscous or large-volume liquids.

Key Specifications

Application Profile

An overhead stirrer is only as good as the shaft that couples its motor to the medium. The 231384 is the Φ8 mm steel shaft matched to the LT400/500 stirrers' drill chuck — the standard 8 mm diameter these stirrers are built to grip. A 500 mm length reaches into taller vessels or lets the impeller sit at the right depth in a large beaker or reactor, and steel construction handles the torque of the higher-power LT models when driving through viscous fluid. Fit an appropriate impeller or paddle to the shaft for the medium and vessel at hand, and secure the stirrer to its stand and clamp before running.

Frequently Asked Questions

What are the shaft dimensions? 8 mm diameter × 500 mm long, steel.

Which stirrers does it fit? The Yamato LT400 and LT500 overhead stirrers, which use a Φ8 mm drill chuck — this shaft matches that chuck.

Does it include an impeller? No — it is the drive shaft; fit an appropriate impeller or paddle for your medium and vessel.

Why choose a 500 mm shaft? The extra length reaches into taller vessels and positions the impeller at the correct depth in large volumes.

Ordering & Configuration
