HCB70XX Standard Series Hybrid Ceramic Ball Spindle Bearings

HCB70XX Hybrid Ceramic Ball Bearings

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.

The rings of hybrid ceramic angular contact ball bearings (HCB series) are made of bearing steel, and the rolling elements are made of silicon nitride (ceramic Si3N4). Silicon nitride rolling elements provide higher bearing performance and extend bearing life even under harsh operating conditions. Compared with steel balls, ceramic balls are lighter and have a higher elastic modulus. Ceramic ball bearings have lower operating temperatures and smaller thermal expansion coefficients. Therefore, hybrid ceramic bearings have high stiffness, high rotational speed, and small internal centrifugal and inertial forces.

Therefore, the rolling contact stress of the outer ring at high speed is minimized. The friction heat of the ceramic ball is small, the energy loss is low, and the service life of the bearing and grease is longer. When subjected to frequent rapid starts and stops, slipping is not easy to occur. Scratching and cage damage, less sensitive to temperature differences within the bearing, higher preload/clearance control accuracy. Compared to bearings using steel balls, hybrid ceramic bearings (using ceramic balls) can reach higher rotational speeds without a significant increase in preload due to the smaller mass of the ceramic balls. Ceramic bearings are now widely used in high-speed working environments. Using hybrid ceramic ball bearings, the working life of the spindle and machine is significantly increased, and the system is more adaptable. These have a positive impact on machining quality.

Our company has professional sales and technical engineers who are responsible for providing users with technical consultation, technical services and product technology training on precision bearing information, installation and use.
