Deep groove ball bearings represent a widely employed bearing type characterised by low friction properties. When optimised, they can reduce noise and vibration, thereby enabling high rotational speeds. Capable of withstanding radial loads and axial loads in both directions, they are straightforward to install and require less maintenance compared to other bearing types. FGFA deep groove ball bearings are customisable, offering advantages for applications with specific performance requirements.
