HC70XX Series Hybrid Ceramic Ball Spindle Bearings

HC70XX Bearing with small Ceramic balls

HC70XX series hybrid ceramic ball bearings mainly use small ball design and divided into two types: medium-load HC70 series hybrid ceramic ball spindle bearings and light-load HC719 series hybrid ceramic ball spindle bearings. HC series hybrid ceramic ball bearings do not have seals and can run in high speed. 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 speeds, they can suppress the increase in internal load caused by centrifugal force compared to steel balls and extend their life.

Hybrid ceramic ball angular contact ball bearing (HC series) rings are made of bearing steel, and rolling elements are made of silicon nitride (ceramic). 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 speed, small internal centrifugal force and inertia force, so the outer ring rolling contact stress at high speed is minimized to the greatest extent.

Ceramic balls have low friction heat and low energy loss, and have longer bearing and grease service life. When subjected to frequent rapid starts and stops, they are not prone to slipping, scratches and cage damage. They are less sensitive to temperature differences in the bearing and have higher preload/clearance control accuracy. Compared with bearings using steel balls, hybrid ceramic bearings (using ceramic balls) can achieve higher speeds without significantly increasing preload due to the smaller mass of ceramic balls. Ceramic bearings are now widely used in high-speed working environments. With hybrid ceramic ball bearings, the service life of spindles and machines is significantly improved, 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 technical training on precision bearing information and installation and use. Perfect pre-sales, in-sales and after-sales services constitute a guarantee system for high-quality services, providing users with reliable quality bearing products and creating excellent user experience and rich benefits for every customer.
