📏 Dimensional Table (Inch):

💡 What’s the benefit of using a dry, open bearing?
Open bearings with no grease or seals are great when you need ultra-low resistance and plan to apply your own lubricant, or none at all:

• Lower rolling friction, ideal for high-speed spinners or performance RC

• No seal drag means higher RPM potential

• Easier to inspect and clean

• Not ideal for dirty environments without shields or grease

☑️ Often used in precision spinning toys, micromotors, and RC vehicle mods
