Ball bearing bearing D series

angular-contactsuper-precisionheavy-duty

D design bearings (fig. 1) are designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures. When compared to other precision angular contact ball bearings, D design bearings contain the maximum number and size of balls. Their close osculation provides a relatively high degree of stiffness and the highest possible load carrying capacity. Applications Typical applications for bearings in the 718 .. D series include: machine tools, e.g. multispindle drilling heads (fig. 2) robotics printing measuring systems racing car wheels Typical applications for bearings in the 719 .. D and 70 .. D series include: machining centres (horizontal and vertical) (fig. 3) milling machines lathes (fig. 4) external and surface grinding machines boring machines machines for cutting or polishing stones and glass semiconductor industry, e.g. units for detecting defects on silicon wafer chips (fig. 5) boat gyrostabilizers telescopes microturbines racing/super car wheels medical equipment
