Deep groove ball bearings are the most common bearing type, featuring two rings, a cage, and a row of balls that handle radial and axial loads in both directions. They are found in electric motors, pumps, fans, gearboxes, and machine tools. We supply the NTN line with metric sizes and light, medium, and extra-light series to match different speed and load needs.
The ZZ suffix on an NTN deep groove ball bearing tells you the bearing arrives with a metal shield on each side. Inside is a single row of balls that handles radial and axial load in either direction, which is why this design turns up so often wherever a straightforward, high-speed bearing with minimal upkeep is required. Motors, pumps, fans, gearboxes and other transmission equipment are typical homes for it.
The NTN EC series deep groove ball bearing handles radial and axial loads in rotating machinery. Its single-row design with deep raceways supports high-speed operation and long service intervals. Typical applications include electric motors, pumps, fans and industrial drives. MR Industrial Accessories supplies this line with ZZ sealing for dusty or humid conditions.
