Duration 5 Days
Introduction
The most common machine element found between what moves and what doesn't is an anti-friction bearing. This course introduces a maintenance employee to the basic types of bearings and common nomenclature used. Bearing installation and maintenance is discussed with a focus on preventing premature failure. The student is also trained to analyze failed bearings so a similar occurrence will not happen again.
Who Should Attend:
Those involved with lubrication, oilers and maintenance personnel, engineers and technicians engaged in equipment design, tribologist and lubrication engineers, operations, material selection, purchasing and research and development.
Course Objectives
At the end of he program participants will be able to:
- Evaluate and select appropriate lubricants for a wide variety of rolling element bearing applications.
- Choose an appropriate grease base, stiffness, base oil and additives, if needed, for proper operation.
- Choose the correct oil viscosity, delivery method (standing oil, circulating oil, air/oil, oil mist) and oil change out intervals.
- Evaluate filter effectiveness, and to select and apply appropriate filter(s).
- Troubleshoot common lubrication problems and recommend corrective actions.
