HCB70XX standard series hybrid ceramic ball spindle bearings mainly use standard ceramic ball design, there are three types design: medium-load HCB70 series standard hybrid ceramic ball spindle bearings, light-load HCB719 series standard hybrid ceramic ball spindle bearings and light-load HCB72 series standard hybrid ceramic ball spindle bearings. HCB series hybrid ceramic ball bearings adopt conventional standard ceramic ball bearings without seals on both sides. Using ceramic material silicon nitride Si3N4, ceramic balls have the characteristics of high speed, low heat generation, high rigidity and high reliability. Bearings using high-precision ceramic balls can achieve higher precision processing. Ceramic balls are lighter than steel balls. When running at high speed, compared with steel balls, they can suppress the increase of internal load caused by centrifugal force and extend life.
