Ball Bearings

Technical Information【BALL BEARINGS】
Ball bearings are used to reduce friction of a rotary shaft mounted on the machine. Reducing friction helps increase the machine efficiency, extend lifespan and prevent seizing and failure. Ball bearings consist of balls (rolling elements), the inner ring, the outer ring, the cage (for keeping the balls in appropriate motion), and are used for many machines requiring rotary shafts, such as motors equipped in electric tools, etc. Types of ball bearings are as follows; angular bearings which support radial and axial loads by combination of single row and double row, thrust bearings which support forces acting in the axial direction of a rotating object, and self-aligning bearings used when the inner and outer rings of a bearing are tilted. In addition to materials, sizes, basic load ratings, and allowable rotational speeds, there are a wide variety of types of shields, greases, outer ring types, etc., requiring you to select a suitable ball bearing for the application.

Thin Section Four-Point Contact Ball Bearing

RBC BEARINGS

The X-Type, or 4-point contact, ball bearing is ideal for moment loading. X-Type bearings are designed with gothic arch raceways creating 4 contact points between the balls and the raceways. This design is excellent for moment loading and reversing axial loading. The X-Type bearing can be used for other light loading conditions, but is not recommended in place of the C- or A-Type bearing for pure radial loads.

Thin Section Ball Bearing

RBC BEARINGS

The C-Type, radial contact ball bearing is designed with deep ball grooves to withstand high loads. Although this bearing is used primarily in applications with radial loads, it can withstand moderate axial loads, reversing axial loads, and moment loads.

Days to Ship: 7 Days
Thin Section Angular Contact Ball Bearing

RBC BEARINGS

In applications with high axial loads the A-Type, angular contact ball bearing should be used. This bearing also works well in radial or combined radial-thrust applications. The A-Type bearing should never be used alone to support moment loads or reversing axial loading.
