Deep groove ball bearings are the most widely used and representative type of rolling bearing. They have a simple structure and are easy to use, making them a versatile choice for handling radial loads and certain bidirectional axial loads.
Rubber-sealed type (RZ, 2RZ, RS, 2RS) rubber seals provide better dustproof, waterproof, and oil-resistant performance, making them suitable for harsh working conditions. Grease is pre-filled at the factory.
