X$DUltra motors–
built to a
higher standard
Six Star Bearing System™
Bearings, the life force of a motor, are what keep
the X$D Ultra running smoothly. These features
protect and lubricate the bearings, adding to the
durability and longevity of the X$D Ultra.
• Single shielded bearings on both ends open toward
the grease cavity to allow maximum opportunity
for grease circulation.
• Cast-iron bearing caps with gaskets retain
lubrication and protect the bearing system
from contaminants.
• Low temperature rise designs– 15% cooler on
average than IEEE standards– increase bearing life.
• Overall vibration of
0.04 ips peak results
in smooth, reliable
operation and extends
bearing life.
Rotor assembly
balanced to ISO 1940
Grade 1.0 for low
vibration.
The vibration level is
50% lower than the
requirement of IEEE
841 - 2009 Standard and
3.75 times better than NEMA Standard balance.
• 130,000 hour L10 direct connected and 50,000
hour L10a belted bearing life increases uptime and
decreases repair costs.
• Full charged lubrication system with a temperature
resistant polyurea grease suitable for a wide
temperature range (-40°C to +130°C).
Safety
• Safer lifting is possible with
a four point lifting system
versus a single eyebolt.
Cast-in lifting lugs
eliminate eyebolts
that may strip,
shear, get lost or be
improperly selected.
• Extended grease
fittings for easy and
safe access.
