Dynaroll: Ball Contact Angle for Ball Bearings

Contact angle is the angle between a plane perpendicular to the bearing axis and a line joining the two contact points between the ball and the inner and outer raceways. The initial contact angle ao is defined as the contact angle when the bearing is subjected to a minimal axial load to remove the looseness resulting from radial play.

Ball Bearing Types & Appliions | SPB-USA, LLC

High-Precision Angular Contact Bearing. Angular contact ball bearings are unique in that their inner and outer rings are displaced relative to one another, creating a contact angle in the direction of the load-bearing axis. This unique configuration allows angular contact bearings to accommodate heavy thrust loads along with radial loads.

What Electric Motor Bearings Should I Use for This

Oct 07, 2020· Ball Bearings. Ball bearings are used extensively in high speed or high precision appliions. They typically support shafts that require low friction rotation, which is why they are often called anti-friction bearings. Self-aligning ball bearings are engineered to handle radial loads where self-alignment ±4° is required.

Radial Play (Internal Clearance) in Ball Bearings

reduced ball to raceway stresses . Greater values of radial play result in higher values of contact angle. Under these conditions, this will provide longer bearing life, lower torque, and less axial deflection. In a pure thrust situation, a 15° increase in contact angle can result in over a 70% reduction in contact stress (ball-to-raceway).

Rolling element bearing components and failing frequencies

Influence of the variation of the contact angle in the bearing failing frequencies. Bearing failing frequencies, according to the mathematical formulas expressed above in Figure 9.2, depend on the contact angle, hence any slight variation of this will result in a variation of the ideal bearing failing frequencies, making it difficult to identify these frequencies in the spectrum.
