KOYO 6216C3 Open Ball Bearing is a KOYO-brand ball bearing identified by the 6216C3 designation and provided in an open (unsealed) configuration. The "C3" suffix denotes a specific internal clearance class, indicating a defined radial play for particular lubrication and operating conditions. As an open bearing, it has no seals or shields, making external lubrication and inspection within the bearing housing feasible where such maintenance is provided.
