Critical Rotational Speed. At θ=0° and cos θ = 1, the gravitational force pulling the media off the mill was maximized. Substituting and solving for speed rotational provides the expression for quantifying the critical velocity, vc ν↓C = 42.3 / √(D-d) revs/min; The above equation assumes no friction between the media and the liner.

Bearing selection for low-speed applications Kaydon

Stiffness is another critical factor for low-speed applications. Specified as a spring rate, this is what determines the deflection of a bearing under load. Many factors contribute to stiffness, including the configuration of the bearing, its diameter, preload, and how it will be supported.

Critical speed Wikipedia

In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration.
