💡 Why use a bearing with mixed shields like Z and RS?
Bearings with a metal shield on one side and a rubber seal on the other provide a balance of protection and speed. The rubber seal keeps out contaminants, while the metal shield offers low-friction performance - ideal when both protection and efficiency matter.

A smart pick for compact machinery where balance between shielding and performance is key.
