What are the advantages of the Deep Groove Ball Bearings design?
The inner and outer raceways are deep grooves, with point contact between the steel balls and the raceways, resulting in low friction and low heat generation. The structure is simple and compact, capable of withstanding combined radial and bidirectional axial loads, with high limiting speeds, low noise, and some compensation capability for installation angle deviations, facilitating high-precision mass production.
What are the advantages of Deep Groove Ball Bearings compared to similar products?
Compared to angular contact ball bearings, they can withstand bidirectional axial forces and do not require pairing; compared to cylindrical roller bearings, they can withstand axial loads and have higher speeds; compared to thrust ball bearings, they can simultaneously withstand radial forces. They offer balanced overall performance, achieving the optimal balance in cost, speed, load capacity, and ease of installation, making them the most versatile.
What are the applications and classic applications of Deep Groove Ball Bearings?
They are widely used in motors, automotive alternators and gearboxes, household appliances (washing machines, vacuum cleaners), water pumps, and precision transmission equipment. Classic applications include rotor supports for small and medium-sized motors, automotive alternators, air conditioning compressors, and roller-type moving parts, making them the most common type of bearing in rotating machinery.
