RS PRO Flanged Radial Deep Groove Ball Bearing with Double Shield, Stainless Steel


Introducing the range of RS PRO Radial Deep Groove Bearings, ideal for applications that require load transfer from rotating parts to housings using the least amount of friction, like electric motors, office machinery and much more. The bearing is extremely hard wearing and durable to ensure optimum performance and reduce the risk of the bearing becoming deformed during use and under heavy load.

Features and Benefits:


  • The high-quality RS PRO Radial Deep Groove Ball Bearings are ideal for applications that need to take on the load of one rotating part to a housing with the least amount of friction

  • The deep groove design of the bearing ensures it is extremely durable and hardwearing to ensure high performance even at higher load transfer and additional stability for the balls

  • In addition to this, the stainless-steel material offers a smooth, corrosion resistant surface, even when it comes into contact with oils, chemicals and corrosives

  • The flange on the bearing makes sure that the bearing is optimised specifically for low noise and low vibration applications, enabling much higher rotational speeds without impacting performance

  • This design also offers quicker and easier installation thanks to the easy to assemble components, while also ensuring there is no damage caused to the bearing internals

  • The double shield reduces the risk of unwanted contamination and preserves vital bearing lubrication

Applications:


A radial ball bearing is a type of bearing that most commonly used to transfer loads from a rotating part to a housing, using the lead amount of friction. Designed to run at optimum performance while still providing a long service life as long as lubrication standards are met, 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 experience heavier loads. Radial ball bearings are commonly found in the following:
  • Electric and car motors

  • Household and garden appliances

  • Automation control

  • Office machinery
