Thin Section Angular Contact Ball Bearings

Thin section bearings are available as deep groove ball bearings, four-point contact bearings and as angular contact ball bearings. 

 

718 series and 719 seriea angular contact ball bearings belongs to thin section bearings, because the width of the bearing is too thin.  These thin section ball bearings are usually not offered with shields or seals as standard options. But the angular contact design allows for a wide range of separator options. The standard retainer is fully machined reinforced phenolic or brass cage.

Thin section bearing's Advantages:

  1.  Precision tolerances – meet ABEC 5 or 7 (ISO P5 or P4);

  2. Superfinished raceways – provide a smooth surface to reduce internal friction and vibration.

  3. High-quality ball complement;

  4. Compact size – saves weight and space for both bearing and mating components, helping to reduce overall envelope dimensions.

  5. Duplexing capability – preloaded pairs further increase capacity and stiffness.

  6. Low torque design – minimizes friction and helps to reduce energy input requirements.

Applications:

Glass manufacturing machinery, medical instrument, optical and scanning instrument, satellite communication devices, large welding equipment, semiconductor manufacturing equipment, medical device, textile printer, rotary tables, radar communication, aircraft, aerospace, astronomy instrumentation and industrial robotics etc.,
