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:

linear\_bearing\_housing() 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:

linear\_bearing() Example 1 
include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
linear_bearing(l=24, od=15, id=8);

tab Clamp tab height. Default: 7
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:

lmXuu\_housing() Example 1 
include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
lmXuu_housing(size=10, wall=2, tab=6, screwsize=2.5);



Module: lmXuu_bearing()

Synopsis: Creates a standardized LM*UU linear bearing cartridge. [Geom]

Topics: Parts, Bearings

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

Usage:
