Double-row steel balls: Two rows of balls arranged symmetrically at contact angles (typically 15°-40°).
Inner & outer rings: Angular contact raceways optimized for load distribution.
Integrated cage: Made of nylon or brass to synchronize double-row ball movement.
Bidirectional axial load capacity: Handles axial loads in both directions alongside radial loads.
High rigidity: Symmetric layout minimizes deformation, ideal for precision positioning.
Compact design: Dual-row integration saves installation space.
Superior load capacity:
Axial load: 50%-80% higher than single-row bearings.
Combined loads: Simultaneously handles radial and axial loads (e.g., gearboxes, spindles).
High precision & rigidity:
Reduces vibration and misalignment in precision equipment (e.g., CNC spindles, robotic joints).
Simplified installation:
Single-unit design eliminates pairing requirements (unlike single-row angular contact bearings).
Extended service life:
Optimized stress distribution minimizes localized wear.
Contact angle:
15°: Prioritizes high speed, low axial loads (e.g., small motors).
25°-40°: Prioritizes heavy axial loads (e.g., industrial machinery).
Dynamic/static load ratings:
Calculate based on operational conditions (refer to ISO 281 standards).
Speed limits:
Slightly lower than single-row bearings (20%-30% reduction due to friction).
Materials:
Chrome steel (GCr15): General-purpose for standard industrial environments.
Stainless steel (440C/316L): Corrosion-resistant for food/chemical industries.
Ceramic hybrid: High-speed, anti-electrolysis (e.g., semiconductor equipment).
Sealing types:
Contact seals (2RS): Dust/waterproof, slightly reduces speed capability.
Non-contact seals (ZZ): Low friction, ideal for high-speed applications.
Installation:
Use thermal or hydraulic tools to avoid deformation.
Ensure proper shaft/housing tolerances (recommended H7/k6 fit).
Preload adjustment:
Eliminate clearance via shims or threaded preload (follow manufacturer guidelines).
Lubrication:
High-speed: Synthetic oils (e.g., PAO).
High-temperature/heavy loads: High-temperature grease (NLGI Grade 2).
