Keyword: Vibration Analysis, Early Failure Detection, Sources of Vibration
Vibration produced by rolling bearings can be complex and can result from geometrical imperfections during the manufacturing process, defects on the rolling surfaces or geometrical errors in associated components. Noise and vibration is becoming more critical in all types of equipment since it is often perceived to be synonymous with quality and often used for predictive maintenance.
Keyword: Bearing Preload, Axial Adjustment, Duplex bearings
Preloading and axial adjustment is a vital but still largely misunderstood area of bearing technology. However, when applied correctly, preloading can reduce or overcome the causes of bearing vibration, heat build-up, noise and fatigue. This passage describes the pros and cons of the three primary methods of applying preload to a bearing.
Keyword: Anti-creep Design, Improved Maintainability, Higher Reliability
Earlier this month NSK announced that it has developed a highly reliable anti-creep design roller bearing for preventing the axle wear due to inner ring creep*1 that occurs in tapered roller bearings used in the wheels of dump trucks for mining operations. With the development of this product, NSK will contribute to improved maintainability and higher reliability. NSK is targeting one billion yen in sales for this product in 2016.
Keyword: Magnetal Bearing Techology
Magnetal solutions are based on mechanisms of induction and design of virtual magnetic circuits. Our research by Dr Lembke has launched the name of " magnetic mirroring ". The core of the technology is how to design so that Eddy currents are kept to a minimum.
Keyword: Bearing Performance, Operating Temperatures
Most bearing manufacturers aim to engineer low operating temperatures into their bearing designs. However, these efforts may be wasted if installers don't choose a bearing suitable to the application and its surrounding environment, or if its lubrication maintenance isn't appropriate.
