Precision drive shaft

Precision drive shaft with bearings

NOTE: This is an update kit for previous models. If you are buying the current kit, it has this already; there is no need to buy any upgrades.

In some cases, the black drive shaft is slightly smaller diameter than the pulleys, which may have caused the pulleys to have some eccentricity on the axis, resulting up to ±0.1mm position error (worst case). While a full revolution is 40mm, the 20mm position may be off. This shaft corrects this issue. The diameter of the shaft is almost equal to the nominal diameter of the bearings. To guarantee that the bearings will fit to the shaft, this is supplied with bearings.

You'll get: A stainless steel drive shaft (diameter +0 / -0.05mm), with five ZZ608 flanged bearings.
