The 60 series strikes a balance between ultra-light load requirements and compact space constraints. These stainless steel bearings are designed to minimize the coefficient of friction and enhance response speed. Constructed from SUS420 stainless steel, they resist rusting when exposed to moisture or mildly acidic cleaning agents, thereby significantly extending service intervals in demanding operating environments.
Bearing Features
Their geometric precision strictly adheres to international standards; super-finishing of the raceways minimizes rolling friction and improves energy efficiency. Regarding dynamic stability, the moderate size of the rolling elements results in lower centrifugal forces during high-speed rotation, effectively suppressing temperature rise. Widely used in office automation equipment, financial terminals, and light industrial machinery, these bearings offer excellent hardness that supports frequent start-stop operations while ensuring repeatable positioning accuracy.
