Radial ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls. The standard Conrad-type bearing has a deep-groove construction capable of handling radial and axial loads from either direction in versatile designs that permit relatively high-speed operation.
Single-row, Deep Groove Radial Ball Bearings
These are the most common bearing type with a wide range of applications. Radial bearings are made with very high levels of precision and used in applications where rotational performance and low torque is necessary, but load is a secondary issue. Deep-groove bearings however do have higher load ratings for their size than shallow-groove ball bearings, but are also less tolerant of misalignment.
Ceramic Hybrid Ball Bearings
Ceramic hybrid ball bearings use ceramic balls in place of steel balls and are constructed with steel inner and outer rings. Using ceramic balls that can weigh up to 40% less than steel balls these bearings reduce centrifugal loading and skidding. This allows hybrid ceramic bearings to operate up to 50% faster than conventional metal bearings. The lighter balls in this type of assembly allow the bearing to spin faster, using less energy to maintain speed.
Radial ball bearings are engineered for use in high-speed, high precision applications for:
- General industrial
- High-speed machining and grinding spindles
- High-speed milling machines
- Precision instruments
- Pumps and compressors
- Biotechnology equipment
- Aircraft generators
