Section: Generic Linear Bearings

Module: linear_bearing_housing()

Synopsis: Creates a generic linear bearing mount clamp. ^[Geom]

Topics: Parts, Bearings

See Also: linear_bearing(), lmXuu_info(), ball_bearing()

Usage:

• linear_bearing_housing(d, l, tab, gap, wall, tabwall, screwsize) [ATTACHMENTS];

Description:

Creates a model of a clamp to hold a generic linear bearing cartridge.

Arguments:

By Position	What it does
d	Diameter of linear bearing. (Default: 15)
l	Length of linear bearing. (Default: 24)
tab	Clamp tab height. (Default: 8)
tabwall	Clamp Tab thickness. (Default: 5)
wall	Wall thickness of clamp housing. (Default: 3)
gap	Gap in clamp. (Default: 5)
screwsize	Size of screw to use to tighten clamp. (Default: 3)

By Name	What it does
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

Example 1:

include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
linear_bearing_housing(d=19, l=29, wall=2, tab=8, screwsize=2.5);

Module: linear_bearing()

Synopsis: Creates a generic linear bearing cartridge. ^[Geom]

Topics: Parts, Bearings

See Also: linear_bearing_housing(), lmXuu_info(), ball_bearing()

Usage:

• linear_bearing(l, od, id, length) [ATTACHMENTS];

Description:

Creates a rough model of a generic linear ball bearing cartridge.

Arguments:

By Position	What it does
l / length	The length of the linear bearing cartridge.
od	The outer diameter of the linear bearing cartridge.
id	The inner diameter of the linear bearing cartridge.

By Name	What it does
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

Example 1:

include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
linear_bearing(l=24, od=15, id=8);
