Introduction Under-lubricated bearings run dry and fail. Over-lubricated bearings overheat, blow seals, and contaminate the product. Getting the interval and quantity right is the single highest-impact maintenance practice for extending bearing service life. This guide provides the formulas, tables, and rules of thumb that maintenance teams and reliability engineers use to build lubrication schedules that […]

Introduction Internal clearance is one of the most misunderstood yet critical parameters in bearing selection. Choose the wrong clearance class, and your bearing will either overheat from excessive preload or vibrate from excessive slop. This guide explains what radial internal clearance (RIC) means, what each clearance class (C2 through C5) is designed for, and how
