RS PRO Single Row Angular Contact Bearing


Introducing the range of RS PRO Single Row Angular Contact Bearings, ideal for applications that require high running accuracy as well as radial and axial loads associated with high rotating speeds. The ball bearings have been designed with a built-in 40° contact angle on each row, ensuring the contact angles extend beyond the limits of the bearing, supporting moderate to large axial loads in one direction, as well as light to moderate radial loads. For additional versatility and to accommodate axial loads in different directions, the bearings can easily be paired to create different mounting combinations.

Features and Benefits:


  • The high-quality RS PRO Single Row Angular Contact Bearings are ideal for applications that have high rotating speeds, as well as the need for radial and axial loads and high running accuracy

  • Each bearing comes with a large, built-in 40° contact angle, improving the rigidity of the bearing and allowing moderate to large axial loads in one direction, as well as light to moderate radial loads

  • This design also offers quicker and easier installation because only one bearing needs to be installed, rather than assembling a pair of bearings

  • The bearings can be paired to create different mounting combinations to support axial loads in different directions, for example, DB (Back to Back Mounting), DF (Face to Face Mounting) and DT (Tandem Mounting), allowing additional flexibility

Applications:


An angular contact ball bearing is a type of bearing that has a higher load transfer capacity compared to standard bearings. Designed to run at optimum performance while still providing a long service life, these types of ball bearings can generally withstand longer maintenance intervals because they run quieter and cooler than other types, meaning less downtime for inspection, maintenance and repairs. They are especially useful because the design of them makes them much stronger, allowing them to move axially and radially. Angular contact ball bearings are commonly found in the following industries:
  • Agriculture

  • Industrial Manufacturing

  • Automotive

  • Materials Handling
