• The lowdown on high-performance bearings
  on many factors, including ambient temperature, heat generated by motors and electrical losses, and bearing friction. Bearings generate heat due to internal design, the ring and rolling-element materials, type of lubrication, and loads acting on the bearings, including preload. Preload. Machine-tool...

This phenomenon continues until the bearings. become so severely pitted that fl uting, excessive. noise, and failure occur...
• Basics of Design Engineering: Bearings
  are just a few of the recent developments from bearing manufacturers. Printer-friendly version. Edited by Paul Dvorak, , Kathleen Franzinger. Ball-rail systems. Star ball-rail systems are for machine tools and industrial robots needing rolling-element linear guides. The systems from Rexroth Star...
• MCM : A New Technology in Predictive Maintenance
  , measurement of electrical signals such as voltage and currrent is much more reliable and easy, and the effects of several faults on stator current are well-known([1],[2]). Mechanical faults such as air gap eccentricities, misalignment and ball bearing defects affect the permeance and electrical faults...
• 'Low-surge' inverters
  a downside. IGBT technology can cause bearing problems from electrical discharge. The problems arise because PWM inverters equipped with IGBT switches generate pulsed voltage waveforms that are associated with high rates of change of voltage (high dv/dt). The pulsed voltage waveform with high dv/dt...

• Keeping It Green
  bearings. This gave rise to the integration of an active sensor with a deep-groove ball bearing, widely used in domestic appliances. The bearing sensor is essentially an incremental encoder. It measures accurately down to zero speed, normally generating between 32 and 80 pulses/rev with a maximum...
• White Paper High-Performance Transformer Oil Pumps: Worth the Investment Plant Services
  reduced cooling capacity. Leaking electrical connectors and gasketed surfaces can impair pump performance and allow the ingress of moisture into the oil, as well as oil leaks into the environment. State-of-the-art pumps mitigate these risks in a number of ways, including improvements to bearing design...

Electrical and electronic -- insulation for coaxial cable, fixture and motor lead wire, hookup and panel...
• Using IR Surveys in DUNAFERR Steelworks Complex Diagnostic System
  concerns are the machinery (see Figure 6), electrical systems including motors (see. Figures 7 and 8), and substation condition (see Figure 9). Figure 6. Machine thermography. The thermal image shows a bearing problem. Figure 7. Substation thermography. The thermal image reveals a disconnector...
