How to "Break-In" Your Precision Bearings - GMN Bearing USA

The spindle temperature should homogenize before increasing the RPM. Consider the length of oil feed tubes to avoid insufficient lubriion. The entire delivery system will need to have oil passing through it to ensure there is a small amount of lubriion in the bearing before any rotation occurs.

High Speed Spindle Design and Construction - Modern …

15/8/1998· In general, bearing life, and ultimately spindle life, will depend upon many factors, including speeds, loading, lubriion and bearing size. Computer models are often used to forecast life, however, a typical spindle bearing life for very high speed operation should be in the range of 5000 - 7000 hours, assuming the spindle is not crashed or mis-used.

Bearing rating life | SKF

For modern high-quality bearings, the calculated basic rating life can deviate significantly from the actual service life in a given appliion. Service life in a particular appliion depends not only on load and bearing size, but also on a variety of influencing factors including lubriion, degree of contamination, proper mounting and other environmental conditions.
