Basic Structure & Design
Components:
-
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.
Design Features:
-
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.
Core Advantages
-
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.
-
Key Selection Parameters
-
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).
-
Material & Sealing Options
-
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 & Maintenance Guidelines
-
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).

FAQ
- What types of loads can double row angular contact ball bearings withstand?
- They can carry combined radial load and bidirectional axial load at the same time. Compared with single-row angular contact ball bearings, they feature higher rigidity and stronger anti-overturning capacity, which helps stabilize equipment operation.
- Can these bearings run at high rotational speeds?
- Yes. With optimized internal structural design and precise manufacturing process, our bearings produce low friction and slight temperature rise during operation. They support stable high-speed operation under continuous working conditions.
- What sealing options are available for this series of bearings?
- We provide open type, ZZ metal shield and 2RS rubber contact seal options. Sealed versions can effectively block dust, water and impurities while avoiding grease leakage, making them applicable to various harsh working scenarios.
