Introduction of Linear Bearing
Linear Bushing model LM is a linear motion system used in combination with a cylindrical
LM shaft to perform infinite straight motion. The balls in the loaded area of the nut are in
point contact with the LM shaft. This allows straight motion with minimal friction resistance
and achieves highly accurate and smooth motion despite the small permissible load.The
nut uses high-carbon chromium bearing steel and its outer and inner surfaces are ground
after being heat-treated.
Interchangeability
Since the dimensional tolerances of the Linear Bush's components are standardized they
are in changeable. The LM shaft is machined through cylindrical grinding which can easily
be performed and it allows highly accurate fitting clearance to be achieved.
Highly Accurate Retainer Plate
Since the retainer which guides three to eight rows of balls is integrally molded it is capable
of ac-curately guiding the balls in the traveling direction and achieving stable running
accuracy.Small-diameter types use integrally molded retainers made of synthetic resin.It
reduces noise gen-erated during operation and allows for superb lubrication.
Application
The Linear Bushing is used in a broad array of applications such as slide units of precision
equipment including OA equipment and peripherals measuring instruments automatic
recorders and dital 3D measuring instruments industrial machines
