KOYO Metal Shielded Deep Groove Ball Bearings: One of the most widely used bearing types, these are manufactured with precision metal shields inserted into the outer raceway. The shields fit closely to the inner race, providing protection against light mechanical damage and offering limited protection from the ingress of moisture, dust, and other contaminants while retaining the pre-filled grease for long-lasting, maintenance-free operation.

The shields can be removed for applications that only require a single shield or where additional ventilation is desired. These bearings are ideal for electric motors, pumps, fans, and general machinery requiring reliable performance and durability.

Benefits: Provides light mechanical protection, limits moisture and dirt ingress, lubricated for life, low noise, and cost-effective operation.
