Ball Bearing White Papers
Pacamor Kubar Bearings has consolidated our most requested ball bearing white pages into one convenient location. PKB offers technical expertise available to assist with design and engineering of ball bearings for custom products. Available options include, but are not limited to, custom rings, retainers, balls, shields, seals, lubricants, and packaging. Whether a PKB ball bearing is included in the Original Equipment Manufacturer's design (OEM) or is installed in a high quality overhaul, the Pacamor Kubar Bearings name is one you can trust.
The following pages contain ball bearing white papers to provide supplemental design data, published articles, and anecdotes to aid you in bearing selection and/or bearing design. For additional technical data relative to bearing design and attributes, please visit our Technical pages.
Pacamor Kubar Bearings is regularly published in a number of technical periodicals, such as Machine Design, Motion System Design, Micro Manufacturing, Power Transmission Engineering, and others. Please view the individual PKB ball bearing white papers to learn about PKB ball bearing design news in real world applications.
As supplemental reading to the ball bearing white papers section, readers may wish to visit the PKB ball bearings blog, which is regularly updated with news and commentary about ball bearings in general, PKB company news, new products, and other topics of interest to ball bearing engineers.
Lubrication is an essential element of bearing selection. Proper lubricant can reduce friction, prevent bearing wear, protect bearing surfaces from corrosion, and carry away excess heat from bearing operation.
This guide is for establishing shaft and bearing fits for miniature and instrument bearings when the coefficients of the shaft and housing are similar or when the operating temperature differential between them is nominal.
Bearing installation is as important as bearing design and cleanliness. Improper installation can damage the bearing assembly.
hOW TO GUIDE (SERIES): using a handheld micrometer to measure miniature and instrument ball bearings
For the most accurate measurements, Miniature and Instrument Ball Bearing dimensions should be measured with a calibrated Air Gauge. A good second option is a calibrated Optical Comparitor. On occasion, it may be necessary to use a calibrated Handheld Micrometer to double check a measurement or for simple verification while working in the field.
Proper handling and installation helps to maximize bearing performance and bearing life.
They're the unsung workhorses of microtechnology. Unseen-and, if working properly, unheard-micro ball bearings pervade the microworld.
When Kearfott Guidance & Navigation, a leading aerospace manufacturer, needed a unique bearing for their space flight application, they turned to Pacamor Kubar Bearings (PKB).
Motion System Design interviewed a panel of industry experts regarding the challenges
of designing and manufacturing high quality ball bearings for high speed applications. Pacamor Kubar
Bearings (PKB) is pleased to participate in this important discussion.
During recent years, many users have experienced disastrous field failures and/or costly assembly
hold ups due to substituted or misrepresented parts. For any company that has suffered as a result of field
failures or production delays...
Bearing speed is affected by a variety of factors including bearing geometry. Bearing rings must be ground
to very tight tolerances and polished to a smooth and shiny finish. Bearing steel must be of high quality
with small, evenly spaced carbides.
Pacamor Kubar Bearings (PKB), a domestic manufacturer of miniature and instrument
ball bearings, has gone one step further in enhancing the customer experience by adding a live chat
function to its customer friendly www.pacamor.com website.
Ball bearing assemblies are an integral part of high performance and precision applications.
They mate parts, control movement, locate components, limit torque, and provide rotational or oscillating
functionality. Miniature and instrument ball bearings are used in many high precision applications.
