Product Description

Product Description

Angular Contact Ball Bearings are engineered to deliver high-speed operation, exceptional rigidity, and reliable performance in applica-tions demanding precise control over axial and radial loads. Their unique internal design enables them to efficiently handle combined loads where thrust forces are predominant, making them indispensable in precision machinery and high-performance systems.

Key Features

Optimized for Combined Loads: Features raceways offset in the bearing axis, creating a specific contact angle (typically 15°, 25°, or 40°). This design enables superior handling of simultaneous radial and axial (thrust) loads in one direction.

High Axial Load Capacity & Rigidity: Significantly higher axial load capacity compared to deep groove ball bearings. The contact angle provides increased system stiffness, minimizing deflection under load for enhanced precision.
High-Speed Capability: Precision-ground balls and raceways, optimized internal geometry, and options for specialized cages ( e.g., phenolic resin, machined brass) ensure smooth operation, low friction, and suitability for high rotational speeds.
Precision & Accuracy: Manufactured to tight tolerances (ABEC P5, P4, or higher available), ensuring consistent running accuracy essential for applications like spindles and robotics.
Preload Options: Can be mounted with controlled preload (axial displacement) to eliminate internal clearance, further increasing sys-tem rigidity, reducing noise/vibration, and enhancing positional accuracy.
Mounting Flexibility: Available in single-row configurations (requiring paired mounting - DB, DF, DT) or as pre-set matched pairs (dup-lex) and double-row units for simplified installation and optimized performance.
Versatile Configurations: Standard series include 7000C (15°), 7200B/7300B (40°), and variants with different cage materials, shields, or seals for specific environmental or lubrication needs.
