Special Bearing

Description

Basic Parameters

The basic parameters of the Special Bearing include: It is a special bearing designed for high – end precision fields such as aviation, aerospace, navigation and nuclear industry. It has core performances like resistance to high/low temperature, high speed/heavy load, vacuum/radiation/magnetic field and high – precision positioning. The main material is special alloy steel (such as high – temperature alloy and titanium alloy), and the surface is treated by coating for corrosion prevention and precision grinding. The precision grades are optional as P4 (precision grade) and P2 (ultra – precision grade). It also supports customization of non – standard dimensions and special working conditions (such as extreme temperature and strong corrosion environment).

Product Performance

Extreme Environment Adaptability

Wide Temperature Range Stability: Capable of maintaining structural integrity and lubrication performance in extreme temperatures ranging from -200°C to +600°C, suitable for applications like aircraft engine combustion chambers and spacecraft cryogenic propulsion systems.

Resistance to Complex Media: Constructed with corrosion-resistant alloy materials and sealed technology, it withstands long-term erosion from fuels, hydraulic oils, seawater, radiation, and other media, meeting the demands of marine equipment, nuclear reactors, and other harsh environments.

High Load and Speed Performance

Heavy-Duty Support Capacity: With optimized raceway design and material strength, its dynamic load capacity is 30% higher than conventional bearings, ideal for heavy-load scenarios such as spacecraft robotic arm joints and main shafts of heavy industrial equipment.

High-Speed Rotation Stability: Precision-machined spherical raceways and low-friction cages enable operation at speeds up to 100,000 RPM, reducing heat generation and vibration to enhance the efficiency of aviation turbine machinery.

Precision Manufacturing and Longevity

Nanometer-Level Machining Precision: Critical dimensional tolerances are controlled within ±2μm, ensuring precise 对接 (docking) with mating components for high-precision applications like navigation system gyroscopes and precision optical instruments.

Long-Life Design: Stress distribution optimized via finite element analysis, combined with self-lubricating materials, extends service life by 50% compared to similar products, reducing maintenance frequency for aerospace equipment.

Multi-Functional Integrated Design

Composite Performance Integration: Capable of simultaneously achieving anti-magnetic interference, radiation resistance, vacuum sealing, and other functions, meeting the comprehensive requirements of complex working conditions in nuclear industrial equipment and satellite attitude control systems.
