FAG Deep Groove Ball Bearing is a widely used bearing type with a variety of characteristics and application scenarios.
Basic characteristics
FAG deep groove ball bearings consist of solid inner and outer rings, cages and steel balls. They are simple in structure, reliable and durable, and easy to maintain. They are available in single-row, double-row, open and sealed designs. Due to the standardized processing technology, the outer ring of the open bearing has a groove for sealing rings or dust covers. Deep groove ball bearings have low friction torque and are suitable for high-speed operation.
Load capacity
Deep groove ball bearings can simultaneously withstand bidirectional axial loads and radial loads. Due to the geometry of their raceways and the use of steel balls as rolling elements, they have good axial load capacity. Single-row deep groove ball bearings have limited misalignment compensation capabilities, so they must be accurately positioned to avoid unfavorable rolling conditions of the rolling elements, thereby extending the service life of the bearings.
Sealing and lubrication
Deep groove ball bearings have a variety of sealing forms, such as double-sided gap seals (suffix 2Z) and double-sided lip seals (suffix 2RSR). Deep groove ball bearings with gap seals or lip seals on both sides are usually filled with high-quality grease for lifelong lubrication. For occasions with high corrosion resistance requirements, sealed and open corrosion-resistant deep groove ball bearings can be designed and provided. Application scenarios Deep groove ball bearings are suitable for a variety of application scenarios, including high-speed mechanical equipment and occasions that need to bear radial and axial loads at the same time. Due to its simple structure, low manufacturing cost, low friction coefficient and high speed, deep groove ball bearings are widely used in many industrial fields.
