Systematically Selecting the Best Grease For

Lubrication and Reliability Handbook ScienceDirect

  • How long does a grease last?
  • The figure shows that grease life depends on the product of rotational speed and bearing mean diameter and on the temperature. The quality of the grease has a major impact on the life of the grease (GPF=1 refers to a standard lithium grease and GPF=4 to a much higher quality grease). Fig. 6.
  • How to achieve a long grease life/relubrication interval?
  • To reach a very long grease life/relubrication interval, the bearing design plays a large role. Optimization of the cage design and reduction of the surface roughness of the functional surfaces will increased the grease life. Examples are cage design with a larger grease storage ability, , or rolling elements with improved profile .
  • How can grease life be extended?
  • Grease life can not only be extended by using a more advanced grease. Also the bearing design plays a great role. For example, grease life can be extended by using less rolling elements. Obviously, this will also have an adverse impact on the load carrying capacity. However, the rolling elements promote size flow and thereby starvation.
  • Do we need a grease life model?
  • Advanced bearing life models exist, and as grease life often dominates bearing service life, a grease life model is highly desirable. Unfortunately, the complexity of grease lubrication means that no physical models for the prediction of grease life are available today.
  • What is the difference between oil lubrication and grease?
  • Grease protects against corrosion and lowers friction values, compared with oil lubrication, provided that grease with a good quality and filling rate is applied. A lubricating grease has a finite life [2,3], which is generally shorter than bearing fatigue life .
