Single row deep groove ball bearings

Deep groove ball bearings (gb/t 276-1994), formerly listed as radial ball bearings, are the most widely used rolling bearings. It is characterized by low friction resistance and high speed. It can be used for mechanical parts that bear radial loads at the same time or combined radial and axial loads. It can also be used for mechanical parts that bear axial load, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

In mechanical engineering, double-row deep groove ball bearings stand out for combining deep groove ball bearing reliability with enhanced load capacity. Conforming to GB/T 276-1994, they handle radial and axial loads effectively, making them ideal for diverse industrial applications.​
The Foundation of Design: Structure and Standards​
These bearings feature two rows of precision balls in a single outer ring with dual inner rings (or split inner ring), separated by a cage for optimal spacing. Based on single-row radial ball bearings, the design doubles contact points for improved load distribution. The GB/T 276-1994 standard ensures consistent dimensions, materials, and tolerances, guaranteeing precision and durability.​
Key Advantages for Diverse Load Scenarios​
Double-row deep groove ball bearings manage complex loads by handling heavy radial loads and moderate axial loads in both directions. The deep-groove raceway design distributes stress evenly, reducing concentration and preventing premature failure under misalignment or shock loads. This versatility suits gearboxes, pumps, and conveyor systems with combined load requirements.​
Low Friction Resistance for High-Speed Efficiency​
Precision-finished raceways and smooth balls minimize frictional losses, critical for high-speed applications like electric motors. Reduced friction lowers energy waste and heat generation, maintaining operational temperatures and extending component life. This efficiency supports consistent rotational speeds and reduces maintenance intervals in industrial tools and small motors.​
High Speed Capability for Dynamic Operations​
Balanced design and rigid construction enable sustained high speeds without compromising load capacity. Lightweight cages prevent ball skidding, ensuring stability in automotive transmissions and other dynamic systems. The combination of speed and reliable load distribution meets the demands of fast-paced manufacturing and transportation.​
Applications Across Industries​
Automotive: Used in gearboxes, wheel hubs, and engines to handle radial/axial loads and varying speeds.​
Industrial Machinery: Supports heavy radial loads in machine tool gearboxes and enhances efficiency in pumps/blowers.​
Electrical Equipment: Improves motor efficiency through low friction and high-speed performance.​
General Machinery: Provides stability for conveyor systems and woodworking tools under off-center loads.​
Maintenance and Installation Simplicity​
Pre-lubricated models reduce maintenance needs, while sealed/shielded variants protect against contaminants. Simple alignment and standard fitting make installation easy for new equipment and replacements, extending service life in harsh environments.​
