Precision ball bearings: Care and handling - Bearing Tips

Apr 01, 2016· Mounting Precision Bearings. When bearings are mounted incorrectly, the balls will cause brinelling on the raceway and undermine bearing performance and life. Brinelling, (dents and abrasions to the raceway) as small as 0.1 micron in depth will have an adverse effect on acoustic noise levels as well as causing increased torque levels.

Understand The Bearing Lifecycle | THE RAM REVIEW

Nov 20, 2020· Forcing bearings into place using blunt-strike tools can cause immediate surface brinelling. Bearings that fit too loose or too tight can cause surface scoring, rapid wear, and fatigue failure. When bearings are employed in belt and chain-drive systems, accurate motor, pulley, and gear alignment is essential for their survival.
