Section: Ball Bearing Models

Module: ball_bearing()

Synopsis: Creates a standardized ball bearing assembly. ^[Geom]

Topics: Parts, Bearings

Description:

Creates a model of a ball bearing assembly.

Arguments:

By Position	What it does
`trade_size`	String name of a standard ball bearing trade size. ie: "608", "6902ZZ", or "R8"
`id`	Inner diameter of ball bearing assembly.
`od`	Outer diameter of ball bearing assembly.
`width`	Width of ball bearing assembly.
`shield`	If true, the ball bearing assembly has a shield.
`flange`	If true, the ball bearing assembly has a flange.
`fd`	Diameter of the flange (required if `flange=true`).
`fw`	Width of the flange (required if `flange=true`).
`rounding`	Edge rounding radius, if any. The outermost top and bottom edges are rounded by this amount. The edges of the inner hole are also rounded. If you set `trade_size` and you want edges rounded, you must set `rounding` yourself. This parameter has no default value because the rounding depends on manufacturer and bearing size.
`anchor`	Translate so anchor point is at origin (0,0,0). See anchor. Default: `CENTER`
`spin`	Rotate this many degrees around the Z axis after anchor. See spin. Default: `0`
`orient`	Vector to rotate top towards, after spin. See orient. Default: `UP`
