HCS70XX Small Ball Sealed Ceramic Ball Bearings

HCS70XX Sealed bearing with small Ceramic balls

HCS series ceramic ball bearings are high-speed angular contact ball bearings with small balls with seals on both sides. Sealed bearings can provide a low-cost and space-saving solution for many applications. Angular contact ball bearings with non-contact seals are one of the common designs for machine tool spindles. Double-sided sealed bearings are generally lubricated for life and should not be flushed. This type of bearing is filled with an appropriate amount of high-quality grease in a clean environment, and the surface anti-rust oil can be removed when using it. The seal ring can be made of nitrile rubber and fluororubber. This type of material has the characteristics of high temperature resistance and chemical corrosion resistance, and is also very good in anti-aging and anti-oxidation ability, making it the material of choice for seal rings.

The HCS70XX small ball sealed ceramic ball bearing adopts a non-contact sealing structure that can significantly raise the high-speed performance of the bearing, and can also maintain a stable operating state under high-speed rotation. This feature makes it widely used in high-speed motors, turbochargers and other equipment. This series adopts a pre-lubricated design, and no additional lubrication is required during installation, which simplifies the installation process to a certain extent and improves efficiency. Sealed angular contact ball bearings reduce the possibility of lubricant leakage, greatly reduce maintenance costs, support long-term use in equipment, and reduce the frequency and cost of bearing replacement. Spindle bearings, especially those located at the spindle end, must be effectively sealed.

The non-contact labyrinth seal with dust cover has a compact radial clearance, wide axial clearance and drainage holes, which can effectively isolate cutting fluids, metal chips and dust from the bearing in working and non-working conditions. Sealed grease-lubricated bearings enhance the effect of labyrinth seals and prevent air from flowing in the bearing arrangement. Since the grease life is the bearing life, the appropriate amount of grease and the choice of lubricant are also the key to directly affecting the service life of the machine tool. The sealed bearings have therefore been added with the right amount of high-performance grease.

The widespread application of sealed bearings (ready-to-install, maintenance-free, and lifetime lubrication) has led to the conversion of lubrication from oil lubrication to grease lubrication.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.
