Roller Bearings: Roller bearings utilize cylindrical or tapered rolling elements (rollers) to support heavy radial and axial loads. They are commonly found in heavy machinery, industrial equipment, and automotive components that require high load capacity and shock resistance. Roller bearings are used in applications such as conveyor systems, gearboxes, large industrial fans, and construction equipment.

The deep groove in a ball bearing is a fundamental design feature that enables the bearing to provide smooth and reliable operation, reduce friction, and support loads in a variety of mechanical systems. Its ability to accommodate radial and axial loads while maintaining efficient rotation makes deep groove ball bearings essential components in many types of machinery and equipment.

The deep groove design is particularly advantageous for radial loads, as it enables the bearing to support forces that act perpendicular to the shaft's axis. Additionally, the deep groove configuration allows the bearing to accommodate some degree of axial load, although axial load capacity is typically lower than radial load capacity in deep groove ball bearings.
