One of the keys to ensuring the efficient
operation of your equipment or product is having properly lubricated
bearings. Incorrect or expired lubrication can quickly lead to bearing
failure resulting in downtime or improper operation in nearly all
applications. According to one manufacturer, over a third of bearing
failures can be directly attributed to improper lubrication. If you
have bearings in inventory with expired lubrication, or you need to
order bearings with a specific lubrication requirement, then National
Precision Bearing (NPB) can provide the service you need.
NPB runs a Class 1000 clean room
and is a certified relubrication facility for NHBB, NMB, and RBC
bearings. The clean room is authorized to clean and relubricate
aerospace, miniature, and industrial bearings ranging from 1/8 inch to
30 inch O.D. sizes. NPB currently stocks over a hundred different oils
and greases ranging from the common instrument oil, Windsor L-245X, to
the more exotic Braycote and Krytox greases. Based on your
requirements, we can recommend a grease or oil for your specific
application. Our clean room runs a positive flow filtration system
which filters dust particulates from the air ensuring a clean working
environment. Bi-annual tests reveal an average particulate count
closer to 100 rather than 1000 particles per cubic foot. NPB also
maintains a class 100 flow bench for relubrication and packaging at
class 100 requirements. Perhaps NPB's greatest asset is our
experienced clean room staff which has a combined total of over 110
years of relubrication experience. On average, our clean room staff is
capable of processing 6000 to 7000 bearings each day.
When a bearing is relubricated at NPB, each one
undergoes a meticulous and well documented process. Customers can
either send in their own bearings to be relubricated, or they can order
bearings from NPB and specify their lubrication requirements. In some
cases, the bearing configuration such as shields, seals, or open can be
specified. The bearings are thoroughly cleaned in one of our two
Branson 950R degreasers. These ultrasonic cleaners wash out the old
grease or oil from the bearings. When a customer specifies an oil, the
bearings are dipped into the oil, or the oil is applied at a specific
rate depending upon customer specifications. If grease is required,
the bearings are brought to one of our several Tridak greasing stations.
Each bearing is filled to the proper grease level in accordance with
industry standards or specific customer instructions. The fill levels
are then verified through the use of the lubricant's specific gravity
and monitored by weighing the bearings on a scale accurate to 1/1000 of a
gram. Once the bearings have been lubricated and seals or shields
replaced, they can be packed according to customer's requirements in
vial packs, pill packs, or poly bags. Customers can also specify what
information needs to be placed on the label for each package.
Manufacturer's certifications and relubrication certifications can be
provided showing complete lot traceability of the bearings through out
the entire process. NPB's clean room is also authorized by the U.S.
government to preserve bearings under MIL-PRF-32033 and is capable of
government packaging in accordance with MIL-P-197K.
Just like a well oiled sports car, bearings need
to be properly lubricated in order to maintain optimal performance.
National Precision Bearing can help ensure your bearings are properly
lubricated. If you have questions about the lubrication of your
bearings, or need your bearings to be relubricated, give us a call at
1-800-426-8038.
