Axial and Radial Load Handling: Engineered to accommodate both radial and axial loads, providing stable and reliable performance under varying operational conditions.
Low Maintenance Design: Many models come with sealed or shielded options to prevent contamination, reducing the need for frequent lubrication and maintenance.
Metric deep groove ball bearings are widely used across multiple industries due to their efficiency, compact design, and high load capacity.
Electric Motors and Generators: Provides smooth rotation and low friction, ensuring long-lasting performance in motor-driven applications.
Automotive Industry: Used in transmissions, wheels, and engine components, offering durability and precision in high-speed environments.
Industrial Machinery: Found in pumps, gearboxes, and conveyor systems, contributing to efficient power transmission and motion control.
Household Appliances: Essential components in fans, washing machines, and air conditioners, ensuring quiet and reliable operation.
A metric size deep groove ball bearing consists of an inner ring, an outer ring, a cage, and steel balls arranged in precision-machined raceways. The design allows for smooth and efficient rotation, with options for open, sealed, or shielded configurations to suit different environmental conditions. These bearings are available in a variety of sizes and load capacities, making them adaptable to various engineering needs.
Deep groove ball bearings come in different designs to meet specific performance requirements:
Single-Row Deep Groove Ball Bearings: The most common type, ideal for radial loads and moderate axial loads in both directions.
Double-Row Deep Groove Ball Bearings: Offers higher load capacity and enhanced stability compared to single-row designs.
Sealed and Shielded Bearings: Protect against dust and moisture, reducing maintenance and extending service life.
Miniature and Extra Small Bearings: Designed for compact devices requiring high precision, such as medical equipment and small motors.
Metric size deep groove ball bearings provide an excellent balance of performance, durability, and versatility, making them a preferred choice across numerous industrial applications.
