Back-to-back duplex arrangement Bearings FAQS
QWhat is super-precision bearings ?
AMachine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, as well as low noise and vibration levels are just some of the challenges. Rolling bearings for general industrial applications can only partly fulfill these requirements. Therefore, SKF manufactures a comprehensive assortment of super-precision bearings. super-precision bearings help original equipment manufacturers and end users to further optimize performance parameters of their equipment and applications. The benefits differ depending on the bearing series and applications but include high speed and load carrying ability, long bearing service life, long maintenance intervals and low energy consumption.
QWhat's the application of super-precision bearings ?
ATypical applications for super-precision bearings are: metal cutting and woodworking machinery spindles other machine spindles (e.g. balancing machines) high speed rolling mills printing machinery precision ball screws live centres high speed turbochargers vacuum pumps racing cars boat gyrostabilizers machine components for the semiconductor industry
QWhat's the Super-precision Bearing Lubrication
AImproved reliability, profitability and reduced environmental impact Super-precision Bearing Lubrication Unit To meet the ever-growing performance requirements of high-speed precision applications, SKF has developed the new Super-precision Bearing Lubrication Unit for use with oil-air lubrication in high-speed applications. This system can not only simplify new spindle designs but can also improve the performance of existing designs. This highly effective solution improves lubricant flow and reduces frictional heating in the bearings, enabling them to operate at speeds up to approximately 2.5-3 million n dm. By reducing the operating temperatures and improving oil-air flow, oil consumption and noise levels can also be reduced.
QWhat's the advantage of oil-air lubrication ?
AThe rotational speed at which a bearing reaches its operating temperature limit depends primarily on the heat generated in the bearing (frictional heat) and the amount of heat that can be transferred away from the bearing. One way to reduce frictional heat, particularly in bearings, is to be sure that the correct quantity of the appropriate lubricant reaches all necessary components. Many high speed applications can be lubricated with grease. However, as speeds and the resulting frictional heat increase, grease is typically replaced with an oil lubrication system. Very high-speed applications generally require a precise lubricant delivery system: the precise amount of oil required to adequately lubricate the bearing is continuously delivered by the oil-air lubrication system, thus minimizing friction and operating temperature. Oil-air lubrication system provides the following advantages: increases the bearing attainable speed reduces friction torque and energy consumption reduces environmental impact reduces lubricant consumption maximizes the effectiveness of the lubricant positive pressure within the housing virtually eliminates the ingress of contaminants.
