Development of Bearings with Low Temperature-rise and High .

temperature-rise and high-speed performance for machine tool main spindles. By optimizing the internal design, temperature rise of both bearings has been reduced to approximately half compared with normal types. These bearings can reduce power consumption for cooling machine tools, which is effective for energy saving.

can even reach 1000 kg which proposes extremely high requirements in carrying capacity and stiffness for the machine tool spindles. As a result, oil hydrostatic spindles are normally adopted in large ultra-precision drum lathes to achieve high carrying capacity up to 3000 kg and stiffness more than 850 N/μm [10].

Ultra High Speed Bearings Provide the Key to Machine Tool .

NSK's solution to these problems is the ROBUST series of bearings, designed for ultra high-speed spindles. The ROBUST series of ultra high speed bearings employs a larger number of smaller diameter balls as their rolling elements, enabling them to operate at rotational speeds some 20 percent higher than conventional designs.
