Deep Groove Instrument Bearings Deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer rings. They can accept radial loads, thrust loads in either direction, or a combination of loads. The design of deep groove bearings make them suitable for the addition of closures which help exclude contaminants and retain lubrication. Besides single deep groove bearings with closures, Barden also offers duplex pairs with seals or shields on the outboard faces. Flanged bearings are especially useful in through-bored housings. The inboard side of the flange provides an accurate positioning surface for bearing alignment, eliminating a need for housing shoulders or shoulder rings. Deep groove bearings are available in many sizes, with a variety of cage types. Because of their versatility, deep groove bearings are the most widely used type of bearing.
