Deep Groove Ball Bearing
Bearing Detail 1 Bearing Detail 2

Deep Groove Ball Bearings are one of the most widely used bearing types in mechanical engineering, available in both single-row and double-row designs to accommodate radial and axial loads with low friction and smooth rotation. Offered in a variety of configurations—including open, shielded, sealed, and flanged models—they are adaptable to diverse operating environments, from general industrial machinery to high-demand applications in electric motors, automotive components, and precision power tools.

These bearings are recognized for their high-speed capability and reliable performance under light to medium loads, making them ideal for applications ranging from household appliances and pumps to gearboxes and industrial equipment. Featuring durable steel cages and advanced sealing options, Deep Groove Ball Bearings deliver long service life, reduced maintenance, and operational efficiency in both specialized motor designs and general-purpose machinery.
