Multi-Spindle Head Output Shafts

Start at the head side with the drive feature: show any gear, spline, keyway or coupling that actually appears on the original component. In the middle, mark the bearing and locating seats, shoulders and retaining features. At the tool end, specify the collet, chuck or other tool connection.

A matching tool-side collet size does not prove that the head-side geometry or bearing arrangement will fit. Use the head model and component drawing revision to keep these details together. Photographs should show both ends and the full side profile, with separate close-ups of worn or damaged areas.

Record dimensions from defined reference faces. Do not use a worn seat as the only source for an intended fit tolerance; identify the design requirement or request a drawing review.

State whether the inquiry is for the bare shaft or an assembled spindle with bearings, gears, seals, collet and nut. List the required items individually. A shaft photograph does not establish that every visible accessory is included.

For a tapping head, describe the holder and any axial or radial compensation arrangement separately from the shaft. Provide drilling or tapping size, workpiece material, intended speed and the inspection requirement at the tool connection. The operating limit needs confirmation for the matched assembly, not just the shaft.

Industry references: AutoDrill’s separate spindle, bearing and drive-component listings and Sugino’s tapping-head connection explanation. These illustrate why assembly details matter; they are not claims of FuRui interchangeability with those brands.
