Review on INA Bearing 22000Rpm Rotational Capacity by John Stowers

Used to replace an identical bearing in a gear unit. The geared motor used several of these bearings and all but one lasted 12 years in intermittent service. The one that failed was not lubricated during production so it eventually seized up even though it was only running at 6 rpm. The new bearing was identical (of the same brand) so a perfect replacement for the failed bearing.
