What is the difference between a roller bearing and a ball
Feb 22, 2018· A ball bearing is a spherical unit that accomplishes the same objective as a roller bearing. The real difference has to do with the contact surface between the bearing and the rail. For ball bearings (assuming a perfectly spherical bearing and no deformation), the contact surface is just a single point.

Guide Rails | Thomson | Thomson
Profile rail bearings are generally mounted to structures that are inherently stiffer than the rail. For this reason, the bearings tend to assume the contour of the surfaces to which they are fastened through bearing deflection. When deflection is imposed upon a bearing, especially a preloaded one, resultant forces occur.
