Limits Fits & Tolerence

Course Overview

The subject of “Limits Fits and Tolerance” can sometimes be a little confusing for practicing engineers and technicians. On this course we demystify the topic and provide crystal clear information to increase your understanding.

A limits, fits and tolerance calculator is also provided for practical assistance. Additionally, investing in this type of training courses is to accurately communicate your precision engineering decision also make sense. Ultimately, it’s all about you having the information you need to get it and get on.

Learning Competencies

After compilation of this course delegates well be able to:

  • Learn that in large scale production there is often a system of limit gauging used, which involves checking the mating parts to ensure they fit within the set limits.
  • Discuss and review the system of limits and fits, the types and classes of fits, as well as selection, tolerance and allowance for mating parts.
  • How to calculate and manage variation and its implications on product performance.
  • Explanation, comparison and calculation of worst-case and statistical techniques.
  • Address assimilability, fit, maintaining clearance, ensuring contact, maintaining wall thickness & machining stock, alignment.
  • Compare dimensioning, tolerancing & design.
  • Check geometric variation from dimensions and tolerances and assembly processes.
  • Understand sources of variation and its effects on assemblies.
  • Assembly modeling process, determining if the design, and assembly process will yield acceptable results.
  • How to correct geometry problems found through analysis.
  • Understand and calculate the cumulative variation.
  • Know if the design specified leads to parts and assemblies that will meet their intended requirements.

Who Should Enroll?

  • Service, maintenance, machine repair, or plant/facility engineering staff of an industrial plant, OEM facility, institution, public utility or commercial building which uses rolling bearings and related equipment.
  • Managers and technicians at industrial plants and OEM facilities responsible for bearing performance and reliability.
  • Rotating equipment engineers, reliability engineers, mechanics, and maintenance supervisors.
  • Those interested in bearing and rotating equipment performance.
