Endshield & Pedestal
Sleeve Bearings
These bearing designs incorporate
specially developed multiple labyrinth
floating oil and air-seals. This ensures
dynamic pressure changes inside
the motor will not adversely affect
the lubrication system and allow for
IP56 degree protection. Center flange
bearings are used on larger machines
improving rotor dynamic performance
and overall efficiency. Self-contained
or flood lubricated options are
available along with suitable provisions
for emergency run-down.
Rolling Element /
Anti-Friction Bearings
Ball or roller type bearings on horizontal
machines are regreaseable and operate
smoothly providing long life with low
running noise. They are assembled with
grease in a sealed housing to avoid
contamination and allow for IP56 degree
protection. The lubrication system includes
a suitable pressure relief plug to purge
excess or old grease during lubrication.
Thrust Bearings
Angular contact ball, spherical roller and
sleeve tilting pad (hydrodynamic plate)
thrust bearings are designed to meet
specific project requirements. Depending
upon application, bearings can be self-
contained grease or oil lubricated, water
cooled or flood lubricated.
Vibration
All motors are capable of complying
with the requirements of API 541, 547
or 546 (as applicable). The rotors are
dynamically balanced in two or more
planes. The vibration level is then
checked in the factory before and
after over-speed tests. This check is
designed to prove the stability required
to achieve quiet operation and long
bearing life.
