LG bushings employ rotation prevention function, where 4 rows of circular arc grooves are arranged on shaft, to ensure precision movement. It is dimensionally interchangeable with linear bushing, as outer tube has same OD. Since outer tube and shaft are interchangeable, combination of outer tube and shaft may be selected. Tube OD ranges from 8–15 mm, with tolerances from 0 to -0.011. Tube lengths range from 12–30 mm, with tolerances from 0 to -0.2 and shaft ODs from 4–8 mm.
