Predictive Maintenance - There Is an App for That

Implementing a predictive maintenance (PM) program can be tough. Despite its proven success, many companies have been operating the same way for over 50 years and don’t know where to start. Understanding where to start and where to focus is critical. The intention of this article is to give insight to start and sustain an effective program using today’s technology and devices.

Power Loss and Axial Load Carrying Capacity of Radial Cylindrical Roller Bearings

This paper is intended to enlarge the application range of radial cylindrical roller bearings by means of a more precise determination of thrust load capacity and more cost-effective design.

DC Motor Protection

The purpose of DC motor protection is to extend a motor's lifespan by protecting it from conditions that can damage the motor's windings--both electrically and mechanically.

Alloying Strategy Boosts Powertrain Performance

The development of a new, gas-carburized gear steel, necessitated by a customer-driven specification, has not only increased the power density in an existing gearbox design, but has done so without requiring any significant change to production processes or heat treatment equipment.
