7000 Angular Contact Ball Bearing | Single Row Precision Radial And Axial Bearings
The 7000 series angular contact ball bearing is a mainstream single-row precision bearing designed to withstand combined radial and unidirectional axial loads. Thanks to its unique internal contact angle structure, it differs greatly from self-aligning and deep groove ball bearings, delivering high rigidity, low friction and outstanding high-speed stability. With multiple customizable sealing types and industrial-grade materials, the 7000 bearing is widely used for high-precision, high-speed mechanical transmission systems in various industrial fields.
Common Sealing Types And Features
7000 angular contact bearings support three mainstream sealing structures to adapt to different working environments, ensuring stable operation and extending service life:
Open Type: No sealing structure on both sides. It features minimal rolling resistance and excellent heat dissipation, supporting regular lubrication replacement. Ideal for clean, low-dust indoor environments and high-speed equipment with circulating lubrication systems.
ZZ Metal Shield Seal: Double-sided metal dust shields with non-contact design. It blocks large dust and particle impurities without affecting high-speed operation, with low friction and long durability. Suitable for dry workshops and general high-speed industrial machinery.
2RS Rubber Contact Seal: Double-sided rubber tight sealing structure. It effectively isolates dust, moisture, oil stains and corrosive substances, and locks internal grease to prevent leakage. Perfect for humid, dusty and complex working conditions without frequent lubrication maintenance.
Bearing Material Introduction And Industrial Applications
Chrome Bearing Steel: The standard material for 7000 precision bearings. It offers high hardness, strong wear resistance and excellent fatigue resistance under high-speed and composite loads. With stable performance and high cost performance, it is widely applied in precision machine tools, high-speed motors, water pumps, compressors and general industrial transmission equipment.
304 Stainless Steel: Features excellent oxidation and rust resistance, adapting to humid and dusty conventional environments. It maintains stable precision under medium loads, serving as an economical anti-corrosion option for light industrial equipment, civilian electromechanical devices and general precision machinery.
420 Stainless Steel: Balances high hardness and mechanical toughness with mild corrosion resistance. It resists high-speed friction wear and weak chemical erosion, suitable for precision instruments, optical equipment and portable high-precision electromechanical devices.
440C Stainless Steel: Ultra-high hardness and superior abrasion resistance, adaptable to damp and moderately corrosive workshops. It avoids precision failure caused by long-term wear and aging, commonly used in automated precision equipment and light chemical machinery.
316 Stainless Steel: Premium anti-corrosion material with excellent salt spray, acid and alkali resistance. It works stably in harsh high-humidity and corrosive scenarios, ideal for food sanitary machinery, marine auxiliary equipment and chemical experimental devices.
Product Advantages And Industry Applications
The 7000 angular contact ball bearing core strengths include dual radial and axial load capacity, high structural rigidity, low vibration and stable high-speed operation. Diversified sealing and material options enable strong environmental adaptability for different working conditions. It is widely used in industrial automation, precision machining equipment, high-speed power machinery, pneumatic and hydraulic systems, food processing, marine and chemical industries, providing reliable and high-precision bearing solutions for various medium and high-speed mechanical systems.
