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.
