Keeping those ball mills turning - CBC Australia PTY LTD
From a bearing point of view, there are two bearings at the end of the shaft on the pinion and there are two bearings on either end of the ball mill. And obviously, the ball mill bearings are massive in size – which is why they get a lot of attention and are expensive to manufacture,” explains CBC Australia Engineering Manager Anthony O
(PDF) Hertz Contact Stress of Deep Groove Ball Bearing
Later, some researchers added to the existing theory the fact that the maximum stresses that cause the ball bearings to break are generated below the contact surface [7,[10][11][12][13].

Contact Stress Analysis of NCD Coating on Roll Ball of
The contact stress of bearing ball with NCD coating in elastic contact was analyzed. Factors such as substrate material, thickness of NCD coating, load and interlayer material which affect the shear stress distribution of NCD coating on bearing ball were investigated. The results show that substrate with low elastic modulus and heavy load will

Tutorial of Hertzian Contact Stress Analysis
resultant stresses are not of design significance, but in some cases failure can occur. Ball bearings or kinematic mounts that are repeatedly removed and remounted can start to show damage from fatigue caused by the Hertzian stresses. The Hertzian contact stress equations come in two forms, spherical and cylindrical.
5-DOF Dynamic Modeling of Rolling Bearing with Local

Diagnosis for Radial Rolling Contact Bearing Using
The test bearing simulated a deep groove ball bearing #6204. The balls rolled on the inner raceway without groove shoulders in order to increase stress in a contact surface and accelerate the fatigue test. The inner ring, the outer ring and the balls were made of vacuum-degassed AISI 52100 steel, while the material of the cage was AISI 304.

A Review of Rolling Contact Fatigue
The localized contact stresses in ball and rolling element bearings are extremely high as compared with stresses acting on rotating structural components e.g., shafts . Neglecting the lubri-ion effects, stress in bearing contacts is governed by the Hert-zian theory, where the pressures are in the order of a few gigapas-
