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.

Self-Aligning Ball Bearings - Open, double row.

NTN

The center of the raceway surface of the outer ring is a spherical surface that coincides with the center of the bearing, and the inner ring is a ball bearing with two rows of raceway grooves.[Features]-The ball, cage, and inner ring can rotate freely with respect to the outer ring to some extent.・ Axle deviation caused by machining errors of shafts and housings and mounting of bearings is automatically adjusted.-Since the loading capacity of the axial load is not very large, it is not suitable for places with a large axial load.-If an adapter is used for a bearing with a tapered hole inside, it is often used for a transmission shaft because it is easy to install and remove.[Application]-Ideal for areas where it is difficult to center the shaft and housing.
