Bearing up to special demands
September 1st 2007 Without sacrificing bearing
accuracy, Kaydon
Corporation Reali-Slim
bearings can be optimised
to minimise friction,
outgassing, contamination
and even wear. The
company specialises in
meeting the specific
demands of semiconductor
manufacturing.
Custom Reali-Slim
bearings were chosen by
Applied Materials UK in
Horsham for a gripper arm
assembly on its Quantum X
ion implant machine for the
processing of silicon
wafers. This is a single
wafer, high current
implanter using fixed beam
technology. The gripper
assembly loads the wafer
into the implant chamber
and the role of the Kaydon
bearings is to support the
rotation of the gripper.
UK factory representative
for KAYDON is R. A.
Rodriguez with whom
Applied Materials UK
worked on this project.
The bearing selected was a
customised Type X 4-point
contact bearing that
accepts radial, thrust and
moment loading. It was
supplied with a flanged
outer race for fixing to the
gripper arm plate.
AISI 440C stainless steel
races and balls were a
must as the application
called for contaminant-free,
no-lube operation. More articles from R A Rodriguez UK Ltd: |
