Super-Precision Bearings

Super Precision Bearings for High Performance

Super precision bearings ensure a high level of quality and performance, thanks to their manufacturing process that complies with the strictest production standards. These components are highly reliable, capable of meeting the ever-growing application demands, such as high rotational speeds, load capacity, rigidity, low noise, and durability.

Their primary application is in machine tools, particularly in spindles and high-frequency electro-spindles, but they are also suitable for various industrial applications where high performance is required. They are widely used in ball screw supports, allowing them to sustain high loads while maintaining system rigidity.

Characteristics of Super Precision Bearings

Super precision bearings enable very high speeds, ensuring stable temperature values and increasing system rigidity. Available in a universal mounting version, they can be preloaded rigidly or through springs, guaranteeing optimal operation even at high-performance levels.

They can be lubricated with oil or grease and are available in both shielded versions, which provide better protection against external contamination, and pre-lubricated versions, with lubricants specified by the customer.

The wide dimensional range of the high-speed version (STANDARD series - ISO 10, ISO 19, and ISO 02) and the ultra-high-speed version (ROBUST series – ISO 10 and ISO 19) allows their use in any configuration.

The introduction of the new ROBUST DYNA series will provide the ability to maintain the maximum speed levels of the ROBUST series, while significantly increasing load capacity and, consequently, the bearing lifespan under the same load conditions. This new series is the ideal solution for high-speed rough machining operations.

High-Performance Materials

Super precision bearings are available in various material configurations:

• Bearing steel (100Cr6)
• Hybrid version, with ceramic balls (Si3N4)
• Special steel (SHX) combined with ceramic balls, allowing speeds up to 3.2 million nDm

In addition to the before and after-sales service, when you buy from us you have the guarantee of receiving an original component. Bianchi Industrial guarantees the origin of components coming from its distribution network with the Bianchi Original Components mark on packaging.
