Do you experience chronic bearing failures, have you checked multiple possible causes such as lubrication, misalignment, imbalance, among others, and the problem persists? There are silent bearing killers that few people know about because they are never seen—they are too small for the human eye—and they are called fits and tolerances. With Mecanicapp, we uncover them immediately! The app will guide you through the process in a simple way to determine the required fit in the bearing supports, machining tolerances, tolerance verification through measurement, and radial clearance verification after assembly.
