HUP Series – Hision

The large-diameter spindle is supported by long-span precision bearings, which can obtain extremely high precision and rigidity. The large-diameter W-axis spindle box is also optional, which can reduce the original length of the cutting tool when approaching the working piece and thus effectively increase the cutting rigidity.

An explanation of bearing internal clearance or radial play

Internal clearance or radial play is the amount of looseness between the balls and raceways of a bearing. For the actual clearances used in the radial play groups, please see our RADIAL PLAY TABLES. Radial play is the clearance measured perpendicular to the bearing axis or more specifically: average outer ring raceway diameter minus average inner ring raceway diameter …
