Single Row Angular Contact Ball Bearings

What are Single Row Angular Contact Ball Bearings?

Angular contact ball bearings are designed for combined loading. This rolling-element bearing variant uses a single row where the balls rotate for smooth flow along the angular contact with the bearing raceway and shoulder. This design supports higher axial loads effectively, supported by corrosion resistant coatings for superior performance. 

Features of Single Row Angular Contact Ball Bearings

  • Single row angular contact bearings have high unidirectional thrust capacity.
  • Two single row angular contact bearings side by side will manage the axial thrust from the other side depending upon the direction and intensity of axial force.
  • The design is optimized for duplex mounting in sets to optimize performance outputs.
  • The contact angle is the highlight of this bearing. This helps support radial and axial loads. The axial load capacity increases with contact angle, which is the line joining the raceway and the ball bearing at the radial plane.
  • The lower shoulder of the roller bearing allows for more balls which increases radial load carrying capacity.
  • These operate at different contact angles ranging between 0° to 40° to help transfer heavy load effectively on the bearing.
  • These have a precisely engineered raceway-shoulder transition that reduces contact and edge stress, to prevent axial overloading.
  • Improved running accuracy is achieved with low friction, noise, and vibration, but high rotational speeds.

Benefits of Single Row Angular Contact Ball Bearings

  • Improved wear resistance: The smooth design placement of the raceway and shoulder angles ensure reduced wear and tear. Thereby scoring high on longevity and sustainability in the long run. 
  • Axial overloading protection: Design dynamics of the bearings helps manage unidirectional axial stress and smoother operations. 
  • Silent and smooth: The shoulder and raceway dynamics are smooth giving very limited scope for friction. This also helps to keep the vibration to a minimum.
  • Less heat generation: The design prevents overheating with enough scope to let out the heat. This directly translates to less machine downtime and long-lasting service life.
