Applications
These bearings are widely used in machinery, automotive, and other heavy-duty equipment where higher load-bearing capacity and durability are essential. The 6400 series provides efficient performance, reduced maintenance needs, and long service life, even under challenging conditions. Their robust design allows them to perform well in environments with higher operating temperatures, vibrations, and heavier loads.
