Ball Bearings（Type：Angular Bearing (Double)）

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.

Angular Contact Ball Bearings - Open, Single or Double Row, Steel or Stainless Steel.

NSK

A ball bearing that can simultaneously support a radial load and a large axial load in one direction.[Features]
-Contact angle type of 15 degrees, 25 degrees, 30 degrees, 40 degrees
-Various cages made of polyamide, steel, and brass[Use]
-Hydraulic pump that applies axial load in addition to radial load, vertical
Can be used for mold pumps, spindles of machine tools that require improved shaft rotation accuracy and rigidity, grinding spindles, electromagnetic clutches for automobile air conditioners, etc.

Angular Contact Ball Bearings - With or Without Seals, Single or Double Row.

NTN

Angular contact ball bearings that can receive a certain amount of axial load.[Features]-The straight line connecting the contact points between the ball and the inner and outer rings has an angle with respect to the radial direction.-Radial load and unidirectional axial load can be applied.-When a radial load acts, an axial component force is generated, so two are generally used facing each other.[Application]-Ideal for machine tools, feed screw mechanisms, ball screw support units, etc.

Angular Contact Ball Bearings - Double Row.

NTN

A bearing with a structure in which single-row angular ball bearings are combined on the back (DB) and the inner and outer rings are integrated.
[Features]
・ The contact angle is 25°.
・ It can receive radial load and axial load in both directions, and also has a load capacity for moment load.
・ This bearing is also available in a sealed type or a shield type, and the rated load changes compared to the open type.
[Applications]
・ Machine Tools.
・ Feed screw mechanism.
・ Ball screw support unit.
