Rolling-element bearings consist of rolling bodies which move in races. They can be loaded radially or axially or in both of these directions. The basic forms are shown in Fig. 9.1. The rolling elements can be balls, rollers, tapered rollers, spherical rollers or needles (Fig. 9.2). These rolling bodies are positioned within a cage, which holds them at

Ceramics in Rolling Element Bearings
SAE Technical Paper Series, 1979<div class="htmlview paragraph">The feasibility of using hot pressed silicon nitride (HPSN) for rolling elements and for races in ball bearings and roller bearings has been explored. HFSN offers opportunities to alleviate many current bearing problems including DN and fatigue life limitations, lubricant and cooling system deficiencies and extreme

Abstract Hollow rolling elements produced by electrodeposition on a removable substrate compared favourably in rolling contact fatigue resistance with conventional ball bearing material. They appear potentially attractive as lightweight rolling elements to reduce centrifugal forces and increase the fatigue life of high speed bearings.

Optimum Design of Rolling Element Bearing
2015The primary objective of this research is to optimize the dynamic load capacity of a deep groove ball bearing. The dynamic load capacity is formulated as an objective function along with the prescribed geometric, kinematics and strength constraints. The non-linear constrained optimization problem is solved using particles swarm optimization (PSO).

Contact fatigue in rolling-element bearings
Engineering Failure Analysis, 1997Abstract Surface contact fatigue is a common cause of failure in rolling-element bearings. The extent of damage observed depends on the contact loads, the curvature of the rolling elements, and the relative motion between the contacting surfaces. The characteristics of the various types of contact fatigue are as follows: 1.

Ballbots rolling elements shape determination
2016 21st International Conference on Methods and Models in Automation and Robotics (MMAR), 2016This paper presents a mathematical method of determination of optimal shape of cooperating rolling elements of spherical shape, i.e. the ones used for drive transmission in ballbots. The presented method takes all geometric parameters of such devices into account and can be easily adjusted to a wider selection of devices.
