3309ANTN Bearing 45x100x39.7mm
The 3309ANTN bearing is a Angular Contact Ball Bearing with an inner diameter of 45 mm , an outer diameter of 100 mm, a width of 39.7 mm. It typically uses P5,P2 grade precision tolerances and No seals type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, dentistry equipment, the centrifugal forces generated by the balls will change the contact angle at the inner and outer race.
The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
