💡 Why are open deep groove ball bearings preferred in high speed lubricated systems?
Open bearings are designed to run clean and fast when lubrication is well managed.

• No seals means lower friction and less heat buildup

• Oil or controlled grease reaches the raceways directly

• Slim profiles fit tight spaces without sacrificing smooth rotation

Use this bearing when you want efficient, high speed operation and easy lubrication control in compact mechanical setups.
