Structural Characteristics

Precision Roller Design: The BAR10/19 Ultra High Frequency Spindle Bearing features specially designed rollers. The contour of these rollers has been optimized to minimize the contact stress between the rollers and the raceway during ultra-high frequency rotation. This optimized design makes the force distribution of the rollers more uniform at high speeds, effectively reducing local wear and extending the service life of the bearing.
Advanced Cage Technology: It is equipped with innovative cages, commonly made of high-strength engineering plastics or lightweight alloys. These cages not only have excellent wear resistance but also can accurately guide the operation of the rollers in an ultra-high frequency dynamic environment, preventing mutual collisions between the rollers and ensuring the smooth operation of the bearing. Meanwhile, its unique structural design helps to reduce air resistance, further enhancing the performance of the bearing under high-speed working conditions.
High-quality Ring Materials and Processing: The rings are made of high-quality bearing steel, which undergoes multiple fine heat treatment processes to endow the material with excellent hardness, toughness, and dimensional stability. In the processing stage, ultra-precise grinding and lapping processes are adopted to control the surface roughness of the rings at an extremely low level, greatly reducing the rolling friction and ensuring the high-precision rotational characteristics of the bearing, which fully meets the stringent requirements of ultra-high frequency operation.

Performance Advantages

Excellent High-frequency Response Ability: This bearing is specifically designed for ultra-high frequency working conditions and can easily meet extremely high rotational speed requirements. It can still maintain a stable operation state during frequent high-speed start-stop and rapid speed change processes. Its advanced structure and precise manufacturing process effectively suppress the resonance phenomenon caused by high-frequency vibrations, reducing damage to the bearing itself and surrounding components.
Super Strong Load-bearing Rigidity: Although it mainly focuses on adapting to ultra-high frequency operation, the BAR10/19 bearing is not inferior in terms of load-bearing capacity. It can provide reliable support for both axial and radial loads, ensuring that the rigidity of the spindle system is maintained under complex force conditions, without obvious deformation or displacement, and guaranteeing the smooth progress of high-precision machining.
Outstanding Heat Dissipation Performance: During ultra-high frequency operation, heat generated by friction inside the bearing accumulates rapidly. However, this bearing can dissipate heat quickly through optimizing the contact design between the rollers and the rings, selecting materials with a low friction coefficient, and adopting a reasonable lubrication method. It avoids problems such as lubrication failure and material softening caused by overheating, maintaining the stable performance of the bearing during long-term and high-intensity work.

Application

The bearings can be used in the following industries

High-speed Precision Machining: Applied in high-end CNC milling machining centers for processing precision components such as aero-engine blades, ensuring machining accuracy and surface quality.
Electronic Manufacturing Equipment: Used in lithography machines and electron-beam exposure machines to ensure ultra-high frequency and high-precision processing of silicon wafers, improving the yield rate of chips. Its sealing device can also maintain the clean operation of the equipment.
High-speed Motors: Suitable for drive motors of new energy vehicles, auxiliary power motors in aerospace, etc., improving the efficiency and service life of the motors. It is also used in special high-speed motors to ensure stable operation.
Medical Devices: Devices such as medical high-speed centrifuges and ophthalmic femtosecond laser treatment instruments rely on it to achieve stable and precise operation, ensuring the accuracy of test results and the safety of surgeries.
